Rating
Mosquito Swarm is an A-tier evolved ball from the Vampire line. On landing it instantly splits into multiple independent mosquitos, each of which selects a random enemy and deals its own hit. A single throw delivers multiple attacks across the field simultaneously.
The key mechanic is the life-steal on kills: if any mosquito last-hits an enemy, you gain HP. In waves with many weak enemies, this can translate into significant healing from one well-timed throw. It's a natural fit for HP-sustain builds.
The randomized targeting is a meaningful limitation — you cannot focus all mosquitos on the boss, so Mosquito Swarm underperforms as a single-target tool. It excels instead at clearing large waves of weak enemies while recovering HP in the process.
When to Pick
- Wave-heavy stages with large numbers of weak enemies to kill for life steal
- HP-sustain builds that want life steal as an active mechanic rather than passive regen
- AOE-focused builds that want simultaneous multi-enemy coverage
- Vampire-line synergy builds stacking multiple blood-drain effects
Best Characters
| Character | Synergy | Reason |
|---|---|---|
| HP-sustain builds | S | Large weak-enemy waves provide many kill opportunities for HP recovery |
| AOE spread builds | A | Scatter attack covers many enemies simultaneously, complementing other AOE |
| Vampire-line builds | A | Stack with Vampire, Soul Sucker, and similar for maximum life steal output |
Recommended Passives
| Passive | Synergy |
|---|---|
| Life steal enhancement | Increases HP gained per mosquito kill |
| Mosquito count increase | More mosquitos per explosion means more simultaneous hits and more kill chances |
| Per-mosquito damage up | Higher individual hit damage increases kill chance per mosquito |
| Kill-heal amplification | Boosts HP restored per enemy death from mosquito attacks |
| Scatter range increase | Wider mosquito spread covers more enemies per throw |
Tips
- Target dense weak-enemy groups — the more enemies mosquitos can kill, the more HP you recover per throw
- Use as HP recovery tool — time Mosquito Swarm throws against large incoming waves to maximize heal opportunities
- Avoid relying on it for boss DPS — random targeting means poor single-target boss focus; use other balls for boss damage
- Pair with Vampire-line balls — running multiple blood-drain balls together compounds life steal significantly
TL;DR
Mosquito Swarm splits into multiple HP-stealing projectiles on landing, each attacking random enemies and recovering HP on kills. A-tier wave-clearer with life sustain. Strongest in large weak-enemy encounters.
