Rat King vs Vyper

Do

• Plan for Divine Barrier Divine Barrier 6,400 souls Tier 4ArmorPress +45s Cooldown +0.2s Cast Delay +1.5 Out of Combat Regen +6s Buff Duration +600 Barrier +10% Ability Range +10% Radius Builds from Guardian Ward — know which tier it sits in so you are not improvising at the shop.
• Know what Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits looks like. It is the cooldown this lane revolves around.

Avoid

• Walking to lane on the same path every wave against a hero with Vyper's engage range.

Do

• 780 HP with no heal, no barrier until Slither Slither A permanent passive that lengthens her slides, lets her slide uphill instead of stalling, and lets her turn much more sharply while sliding. Mobility +15% slide distance base, +20% more at T1; Defensive T3 grants a 180 barrier for 4s on slide, with an 8s internal cooldown before… 1 +20% slide distance 2 +2 stamina 5 on slide, gain a 180 barrier for 4s (8s internal cooldown); T3, and no damage reduction anywhere
• Lethal Venom Lethal Venom 10m Range28s Cooldown Injects a target with venom that detonates after a short delay. Damage 20 minimum (about 0.65x spirit scaling) up to 140 maximum (about 2.79x… 1 +31.5 maximum venom damage 2 -40% healing reduction and -12s cooldown (28s base) 5 bullets also build up Lethal Venom is only 10m at base, so she has to actually be in the enemy's face to use her best damage tool
• Scrap Grenade Scrap Grenade 26s Cooldown Rat King throws a bouncing lump of scrap that goes off three times where it lands. Crowd Control 20% movement slow for 4s (scales slightly with Spirit). Damage 70 bullet damage per detonation (+0.6 weapon-damage scaling), three… Defensive The slow is his peel: thrown at his own feet it stops a diver from following… 1 -8s cooldown (26s to 18s) 2 +70 damage per detonation 5 one extra, bigger final detonation — 300 damage, 14m radius, 40% slow clears a trooper wave in three hits and slows anyone farming in it, so he wins wave tempo early

Avoid

• Four base stamina plus Slither Slither A permanent passive that lengthens her slides, lets her slide uphill instead of stalling, and lets her turn much more sharply while sliding. Mobility +15% slide distance base, +20% more at T1; Defensive T3 grants a 180 barrier for 4s on slide, with an 8s internal cooldown before… 1 +20% slide distance 2 +2 stamina 5 on slide, gain a 180 barrier for 4s (8s internal cooldown); gives her more dodge and reposition resource than most laners, so she wins movement-based trades
• The Rattler's no-ammo-while-sliding quirk means she can pressure continuously without reload downtime

Do

• Their first real spike is Screwjab Dagger Screwjab Dagger 10s Cooldown Throws a dagger for spirit damage and a movement slow. Crowd Control -28% move slow on first hit, -12% more per stack, lasting 10s Damage 50 base (about 0.8x spirit scaling) plus 25 per stack (about 0.4x scaling)… Defensive The slow is her only way to break a chase 1 +1 charge 2 on hit, -8% bullet resist and an additional -6% bullet resist per stack 5 +2 max stacks, -2s charge delay, and on hit refund 55% of the charge cooldown T2 — respect it from that point, not before.
• Your spike is ult unlock: Rule, Ratannia! Rule, Ratannia! 10s Duration160s Cooldown Rat King raises the banner of Ratannia. Crowd Control Knockup and a 40% slow on the slam, plus Rat Swarm from the rats it… Damage 200 bullet damage on the slam (+1.2 weapon-damage scaling), 20m radius (cut… Mobility +3 m/s movement speed for him and nearby allies for up to 10s while the… 1 +2 m/s movement speed (no cooldown reduction since 5 October) 2 +5s banner duration and +8m radius 5 +150 slam damage and +10% damage reduction turns him into the team's fight-starter: slow immunity and speed on the way in, a 20m Knockup on arrival

Avoid

• Taking an even fight against Vyper on their spike timing when you could take the same fight ten minutes later on yours.

Do

• Watch for Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits . It is a thrown projectile with visible travel — sidestep the direct hit and you take only 50 damage and a 1.5s slow instead of 180 and a 2.2-3.2s petrify
• Root or immobilise her — Warden's Binding Word Binding Word 15m Range34s Cooldown Curses a targeted enemy hero. Crowd Control 1.75s immobilise (T2 adds +0.75s, so up to 2.5s) if the target fails the… Damage 110 (about 2.44x spirit scaling) when it lands Defensive Rooting a diver in place is a strong self-peel 1 Warden deals +20% bullet damage to trapped heroes for 5s 2 +0.75s immobilise duration 5 -14s cooldown (34s base) and silences the target until they escape or are immobilised , Venator's Hex-Lined Snap Trap Hex-Lined Snap Trap 28s Cooldown Kicks out a trap that arms after a short delay and then sits on the ground for up to 30 seconds.

Avoid

• Spending your own escape before Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits is on cooldown.

• Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits Ultimate

  Once this lands the fight is usually already decided — 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); -40% movement slow for 1.5s in the area.

  • It is a thrown projectile with visible travel — sidestep the direct hit and you take only 50 damage and a 1.5s slow instead of 180 and a 2.2-3.2s petrify
  • Spread out so a direct hit can only land on one person; pre-T3 the area component is a slow, not a disable
  • If you are petrified you take no damage, so the correct use is to treat it as a forced defensive window — have your team disengage or reposition during it rather than trying to fight
• Screwjab Dagger Screwjab Dagger 10s Cooldown Throws a dagger for spirit damage and a movement slow. Crowd Control -28% move slow on first hit, -12% more per stack, lasting 10s Damage 50 base (about 0.8x spirit scaling) plus 25 per stack (about 0.4x scaling)… Defensive The slow is her only way to break a chase 1 +1 charge 2 on hit, -8% bullet resist and an additional -6% bullet resist per stack 5 +2 max stacks, -2s charge delay, and on hit refund 55% of the charge cooldown Ability 1

  Not lockdown, but it makes disengaging cost more than it should: -28% move slow on first hit, -12% more per stack, lasting 10s.

  • Break line of sight for 10s and every stack falls off, resetting her whole combo
  • The dagger is a travelling projectile — strafing and using cover during her approach denies the stacks she needs
  • Buy Bullet Resist deeper than she can shred ( Metal Skin Metal Skin 3,200 souls Tier 3ArmorInstantCast +24s Cooldown +5s Duration +12% Bullet Resist -20% Dash Distance , Bullet Armor) so the T2 resist reduction does not open you up to The Rattler
• Slither Slither A permanent passive that lengthens her slides, lets her slide uphill instead of stalling, and lets her turn much more sharply while sliding. Mobility +15% slide distance base, +20% more at T1; Defensive T3 grants a 180 barrier for 4s on slide, with an 8s internal cooldown before… 1 +20% slide distance 2 +2 stamina 5 on slide, gain a 180 barrier for 4s (8s internal cooldown); Ability 3

  It is her movement identity. Combined with her gun not consuming ammo while sliding, Slither lets her circle a target at speed, never reload, and enter and exit fights from angles that other heroes cannot take.

  • Fight her on flat or enclosed ground — Slither's uphill sliding and long slides are worth far less where there is no slope and no room to build speed
  • Root and immobilise effects (Warden's Binding Word Binding Word 15m Range34s Cooldown Curses a targeted enemy hero. Crowd Control 1.75s immobilise (T2 adds +0.75s, so up to 2.5s) if the target fails the… Damage 110 (about 2.44x spirit scaling) when it lands Defensive Rooting a diver in place is a strong self-peel 1 Warden deals +20% bullet damage to trapped heroes for 5s 2 +0.75s immobilise duration 5 -14s cooldown (34s base) and silences the target until they escape or are immobilised , Venator's Hex-Lined Snap Trap Hex-Lined Snap Trap 28s Cooldown Kicks out a trap that arms after a short delay and then sits on the ground for up to 30 seconds. Crowd Control 1.25s immobilize (T2 pushes it to 2.25s) Damage 80 spirit (about 2.2x spirit scaling); Defensive Acts as a tripwire behind Venator so flankers cannot reach him unpunished 1 -11s cooldown (28s base) 2 +1s immobilize duration 5 +1 charge and +30% damage dealt to revealed targets , Vindicta's Stake Stake 40s Cooldown Throws a stake that embeds where it lands. Crowd Control Tether for 1.75s (T3 adds +0.75s) restricting movement to a 9m leash, plus a… Damage 40 spirit base, scaling with Spirit Power; Mobility none for Vindicta 1 +45 damage 2 -22s cooldown (40s base down to 18s) 5 +0.75s tether duration and +2m capture radius ) stop a slide dead and remove both her mobility and her infinite-ammo state
  • The T3 barrier is only 180 for 4s on an 8s internal cooldown; burst through it rather than chipping at it

1. 1 Petrifying Bola Petrifying Bola 115s Cooldown Throws an explosive bola. Crowd Control 2.2s petrify on a direct hit (T3 adds +1s, up to 3.2s); Damage 50 area damage (about 0.74x spirit scaling); Defensive Petrifying an incoming diver removes them from the fight for over two… 1 +49.5 petrify damage 2 -20s cooldown 5 +1s petrify duration and petrifies all enemies in the area, not just direct hits

   Petrifying Bola first — 115s cooldown post-09-16-2026 is the longest cooldown in her kit and her only Hard CC; force a miss and then take the objective

2. 2 Lethal Venom Lethal Venom 10m Range28s Cooldown Injects a target with venom that detonates after a short delay. Damage 20 minimum (about 0.65x spirit scaling) up to 140 maximum (about 2.79x… 1 +31.5 maximum venom damage 2 -40% healing reduction and -12s cooldown (28s base) 5 bullets also build up Lethal Venom

   Lethal Venom second: it is her execute and her anti-heal in one, and at base 28s (16s at T2) making her spend it on a frontliner buys your carry a full rotation of safety

3. 3 Screwjab Dagger Screwjab Dagger 10s Cooldown Throws a dagger for spirit damage and a movement slow. Crowd Control -28% move slow on first hit, -12% more per stack, lasting 10s Damage 50 base (about 0.8x spirit scaling) plus 25 per stack (about 0.4x scaling)… Defensive The slow is her only way to break a chase 1 +1 charge 2 on hit, -8% bullet resist and an additional -6% bullet resist per stack 5 +2 max stacks, -2s charge delay, and on hit refund 55% of the charge cooldown

   Screwjab Dagger third: charges regenerate quickly and T3 refunds 55% on hit, so do not spend resources baiting it — break line of sight to drop the stacks instead

• Essentially no defensive kit: 780 HP and a 180 barrier at Slither Slither A permanent passive that lengthens her slides, lets her slide uphill instead of stalling, and lets her turn much more sharply while sliding. Mobility +15% slide distance base, +20% more at T1; Defensive T3 grants a 180 barrier for 4s on slide, with an 8s internal cooldown before… 1 +20% slide distance 2 +2 stamina 5 on slide, gain a 180 barrier for 4s (8s internal cooldown); T3 is the entire package Strong evidence
• Everything meaningful happens inside 10-33m, so she is helpless against long-range poke Strong evidence

• Her entry — she is a flank carry with no engage tool, so catching her on the approach before she reaches slide speed removes her whole plan Strong evidence
• Your weapon has travel time and Vyper is fast enough to make that matter. Lead into where their movement is constrained rather than where they are — the closer the fight, the less your projectile speed costs you. Strategic
• When Vyper puts up a barrier, do not reset the trade and wait for it to drop. Overflow damage carries through to health, so a single large hit spends the barrier and keeps going in one action — there is no wasted remainder. What does get wasted is chip, because barriers decay on their own and small hits are exactly what a temporary pool absorbs for free. Either commit your burst through it or disengage entirely; the middle option gives them a free absorb. Strong evidence

• Confirming and denying a soul orb is a hit-check, not a damage-check — one bullet or one pellet takes it regardless of how much damage it does. That is good news for you in the abstract and bad news against Vyper specifically, because your projectile has travel time and their hitscan does not. On the contested floating orb you have to pre-fire: start the shot before the trooper dies and lead the orb's spawn point, because if you both react at the same instant they win every time. Strong evidence

• Vyper will be their Urn runner and you are the one who can stop it. The Urn cannot be voluntarily dropped — it comes loose only on melee, a Stun, or death — so chip damage and slows do not deny a delivery, your Hard CC does. Hold it for the carry rather than spending it on the approach fight, and note the favoured team gets +50% Bullet and Spirit Resist in a 60m bubble while carrying and depositing, which is why trying to burst the runner down usually fails. Documented
• There is a hard behavioural change at 20:00 in this matchup: respawn goes from 35 to 38 seconds as of 09-16-2026, and you are the hero Vyper can pick off without a fight starting. Three seconds does not sound like much until you price it against the Rift's 7-minute cadence and the Urn at 20 and 25 — a single death now reliably costs you presence at the next objective. Past 20:00, stop taking the solo camp that is one rotation from their side of the map. Documented

• Stacking a second damage-reduction debuff onto Vyper is close to a wasted slot: since 05-22-2026 total damage-reduction debuffs stack diminishingly rather than additively. If someone on your team already brings one, your souls buy more as anti-heal or as resist shred, both of which sit on different multipliers. Coordinate this before the game rather than discovering it in the fight — two players independently buying Inhibitor Inhibitor 6,400 souls Tier 4ArmorPassive +150 Bonus Health +5s Debuff Duration -30% Damage Penalty +10% Weapon Damage -40% Incoming Healing -40% Incoming Healing against their carry is a common and invisible waste. Documented
• You have peel and Vyper is the dive threat, so your job in the fight is not damage — it is being in range of whoever they are jumping on. Position between their entry point and your squishiest teammate and hold your peel tool for the moment they commit, not for the moment they appear. Strategic

• Vyper wins by choosing where the fight happens. Take your position before the zoning goes down, not after — once the area is committed you are fighting on their terms, and walking in to contest it is exactly the mistake the kit is built to farm. Strategic

• Vyper dives, and you do not have an exit in your kit. This is the clearest item priority in the matchup: buy a movement or escape active before you buy your next damage item. A damage item does not help you if the fight starts with you already dead. Strong evidence

• The specific error is walking into Vyper's area denial after it is already down, because your team is in there and you feel late.

Arrive before the zone or arrive from the other side of it; arriving into it is how this matchup is lost even when your team wins the fight. Strategic
