The elemental alchemist, Orokin executioner, serpent whisperer - Lavos!
Passive: Lavos cleanses all active negative Status Effects and gains status immunity for 10 seconds upon collecting an Energy or Universal Orb. Picking up an Energy or Universal Orb has a cooldown of 5 seconds.
Ophidian Bite - Lash out with a toxic serpentine strike, consuming the target to heal Lavos.
Vial Rush - Dash forward, crashing through enemies and leaving an icy trail of broken vials.
Transmutation Probe - Launch a probe that converts Health and Energy Orbs into Universal Orbs that provide both, and ammo pickups into Universal Ammo Pickups. The probe shocks enemies in close proximity. Each electrocuted foe reduces other ability cooldowns by one second.
Catalyze - Catalyst Probes erupt from Lavos and douse combatants in a fiery gel. Damage is doubled for each element afflicting an enemy.
Acquisition: Main and component blueprints are available from Father with Entrati standing.
Besides the design flaws that others have pointed out already, I can’t play Lavos since his ability chording gives me hand pain after prolonged sessions, and I can’t use my mouse buttons for them without redoing binds or creating a completely separate Lavos-only button profile.
Cooldown-based abilities are also not my thing; I’ve played enough classic MMOs to tire of the timeline optimization meta-game.
