How to beat Seviper in Pokémon GO
Seviper is a single-type Poison raid boss in Pokémon GO. The fight takes 180 seconds; Premier Balls drop based on damage dealt and surviving mons. Lead with super-effective attackers — Pokémon GO multiplies damage by 1.6× for single SE, 2.56× for doubly SE. Bring six top counters plus three backups for the revive cycle.
Lobby size
Seviper sits in the tier-3 raid range. Solo-able by a well-prepared trainer with level-40+ top counters; otherwise two players is more than enough.
Power-up priority
Build at least six of the top three counters to level 35+ before attempting solo or duo lobbies. Pair charged-move unlocks where the listed best-moveset includes a second charge. For raid builds beyond this boss, see the tier list for general attacker rankings, or the raid counter tool to plug in any boss interactively.

How to pick raid counters in Pokémon GO
Raid efficiency comes from one number — damage-per-second multiplied by survivability. Both depend on type matchup, moveset, and stat product (CP × HP). This tool ranks every candidate in your meta against the boss, surfaces the top six, and explains why a counter scores high so you can decide which one to power up next.
The PoGO damage multipliers
Super-effective: 1.6×. Doubly super-effective: 2.56×. Resisted: 0.625×. Doubly resisted: 0.39×. Weather-boost: another 1.2×. Stack these and a doubly-SE weather-boosted attacker hits for ~3× a neutral attacker. That gap is why typing dominates raw IV.
From counter to squad
Pick the top six by score, confirm each has the right charged-move unlock, and verify level (40+ ideal; level 50 for Master League carry-overs). Build a backup squad of three more in the same type for re-entries — most T5 raids take two squads minimum, plus the revive cycle. The in-app screen pulls these from your real collection so you see exactly which six to bring.

FAQ
How are raid counters ranked in this tool?
Each candidate gets a composite score: meta-tier (S / A+ / A …) × type effectiveness against the boss × movepool quality. A Shadow Mamoswine with Powder Snow + Avalanche scores higher against a Dragon boss than a regular Garchomp with sub-optimal moves. The S / A+ / A bucket comes from cross-referenced community tier lists (Pokebattler, GamePress, TheSilphRoad).
What's the difference between 1.6× and 2.56× damage?
Pokémon GO uses 1.6× for single super-effective and 1.6 × 1.6 = 2.56× for doubly super-effective (when both of the target's types are weak to your attack). Resisted is 0.625×, doubly resisted 0.39×. Doubly super-effective counters are nearly always the right pick for time-to-win.
How many counters do I need to solo a tier 5 raid?
Standard rule: six top-tier counters at level 35+ with matching movesets, plus a backup squad of three more in the same tier. Weather boost extends the soft cap. For mega bosses (T6) and Primal raids, you need ~9 high-IV counters or a coordinated 2-3 player team. Use the in-app raid-counter screen to pull your actual collection rather than a generic list.
Why do my hundos still take longer than the timer suggests?
Tier and movepool matter more than IVs. A 14-attack with the recommended fast + charged move pair (Shadow Bonus / Mega-boost) outperforms a hundo with sub-optimal moves. Build the recommended moveset on each top counter before stocking up on hundos.
Does weather change which counters work?
Yes — boosted-type attacks get a 1.2× damage multiplier AND the attacker is treated as 5 levels higher (CP up ~10 %, HP up ~5 %). Cloudy + a Fighting attacker against a Normal boss is the textbook example. The counter ranking shifts accordingly. Check the in-game weather forecast before locking in your squad.
