Corrosion at scale. Contagion hits every enemy in a wide zone at once and applies the Contagious status, which turns each affected target into a small bomb when they die. Against dense waves, the chain of death explosions does more work than the initial spell.
StrategyCast it into the middle of a pack and let the Contagious debuff multiply your damage. Clean up the weakened enemies fast to trigger as many explosions as possible before the debuff expires. Surcharge or Fireball into a Contagion-marked group is one of the more efficient burst windows in the game.
Strengths
Wide zone means it reliably hits multiple enemies per cast
Contagious death explosions scale with group size
Excellent synergy with burst spells from other schools
Weaknesses
Long cooldown requires careful timing
Death explosions require actually killing the debuffed targets
Far Far West lets you stack two spell effects on the same surface or enemy. When the second cast lands on something already affected by the first, the game triggers a combo - a separate effect that's usually stronger than either spell alone. Most combos cross schools, so a balanced loadout matters more than stacking five spells from the same school.
Any Acid PoolBubble · Geyser · Rain+FirebeamFire=Tornado
Fire Beam ignites any acid surface (Bubble, Geyser, Rain) and lifts it into a swirling damage zone.
Rain conducts the lightning - chained strikes hit everyone in the rain zone.
Any Acid PoolBubble · Geyser · Rain+★Any VoodooSchool chip=Healing Candles
Voodoo essence consecrates the pool into a friendly healing candle field.
Any Acid PoolBubble · Geyser · Rain+Any Fire or ElecIgniter / Charger=Chain Reaction
Acid surfaces transmit Fire or Elec damage across every connected pool.
★Any CactusSchool chip+Any Fire or ElecIgniter / Charger=Charged Cactus
Cactus summons (turret, wall, mine, decoy, golem) inherit elemental damage when struck by a Fire or Elec spell. The same trick works with elemental gunshots: a Pistolero hit by an Elec-effect bullet starts firing electric rounds.
Cactus summons (turret, wall, mine, decoy, golem) struck by an Acid spell (Bubble, Geyser, Rain, Thrower) inherit acid damage - their shots and contact hits coat targets in corrosion on top of the physical damage. The same elemental-inheritance trick as Charged Cactus, just on the Acid school.
Any Fire or ElecIgniter / Charger+ThrowerAcid=Acid DPS Burst
Hit a Fire- or Elec-affected target FIRST, then Acid Thrower on top, and the acid detonates into a giant continuous damage burst. Reversing the order (Acid first, then Fire/Elec) only triggers a single tick.
Cactus summons hit by a Voodoo aura (Drain, Rescue, Corruption) turn purple and spread that corruption to every enemy they strike - the stain is transferable between summons and detonates for a wave of corruption damage when the effect ends. Especially strong on Decoy and Betty, since both expire by firing, so the corruption wave goes off automatically.
Spells thrown through Elec Portal are duplicated, so Bandito's huge wave gets cast twice. Devastating against tightly-packed groups and the easiest way to scale the spell's already-high damage. Every player now carries their own pair of portals (up to 8 in a four-player run), so keeping one open for this is easy.
Pistolero turret thrown through Elec Portal spawns a second turret on the other side, so two turrets means double sustained DPS until they expire. With every player now carrying their own two portals, you can set this up far more often.
