Trigger: On hit
Cooldown: ~0.75 sec (shorter at higher domain tier)
Research time: 20 min

Overview

On hit, sprays oil from enemies. Oil sticks to tiles or enemies and can spread further.

Research note

I'm going to need a substantial amount of detergent.

Mechanics

While active, any projectile hit applies On Fire for about 2 to 5 seconds depending on domain layers. While cooldown is ready (about 0.75 seconds base, shortened by domain layers), a hit spawns an oil blob from the impact point, up to 6 plus domain layers on field.

Oil can stick to tiles or enemies and may drip after about 3 seconds. Nearby fire projectiles, or enemies with On Fire, Hellfire, or Cursed Inferno, ignite oil for about 3 seconds. While burning, it deals decaying damage about every 0.25 seconds in range and applies Hellfire.

Tips

Lay oil first, then follow with fire attacks or burn debuffs to detonate. Enclosed terrain helps oil stick and chain ignites. At cap, wait for old oil to fade before adding more.
