Lavos Prime · The kit

Imbue, probe, prime, catalyze

Lavos has no energy bar. Cooldowns are the cost. Hold to mix, tap to spend. Catalyze is the nuke. Valence Formation is the gun. Flow is a dead mod. Never slot it.

Alchemist's Vial

Energy and Universal orbs grant Lavos a few seconds of status immunity — that is what orbs are for, because he cannot spend them on a pool he does not have. Hold any ability to load its element into the mixing vial (Toxin / Cold / Electricity / Heat). The next tapped ability spends that extra element as bonus damage and status. Mixing two basics makes a combo (Heat + Toxin = Gas, and so on).

Ophidian Bite

Cooldown · hold = Toxin imbue

Lash a cone of snakes, eat the target, heal. Hold 1 to put Toxin in the vial without casting. Swift Bite (augment) refunds cooldown when you hit a pack and adds range. This is the heal button and the Toxin ingredient for Gas Catalyze.

Cooldown: Short
Hold: Imbue Toxin
Swift Bite: Cooldown refund on multi-hit

Vial Rush

Cooldown · hold = Cold imbue

Crash forward, leaving broken Cold vials. Enemies on the trail freeze and slip. Hold 2 to load Cold. Duration is trail lifetime. Most nuke configs replace this with Nourish or Sickening Pulse. Keep it if you like moving.

Cooldown: Short
Hold: Imbue Cold
Helminth: Default dump slot

Transmutation Probe

Cooldown · hold = Electricity imbue

Launch a roaming probe. Health and energy orbs become Universal (both). Ammo becomes universal ammo. Nearby enemies get shocked; each one hit reduces Lavos' other cooldowns (Efficiency fattens the shave). Hold 3 to load Electricity. This is the engine. A Synth Fiber pet picks the orbs through his pickup delay.

Cooldown: Medium
Hold: Imbue Electricity
Shave: 1.5s per shocked enemy, Efficiency-scaled

Catalyze

Cooldown · hold = Heat imbue

A ring of catalyst probes races out, coating everyone in Heat (plus whatever you imbued). Damage doubles for each unique elemental status already on the enemy. Prime, then 4. Hold 4 to load Heat. 30-ish second cooldown after they finish traveling — Probe exists to eat that timer. Archon Vitality doubles the Heat proc. Valence Formation also fattens matching status DoTs.

Cooldown: ~30s after travel
Hold: Imbue Heat
Multiplier: ×2 per unique elemental status
