Special Abilities

Detonation (Ex) When the detonation ooze is reduced to 0 HP, the destabilized chemicals that make up its body trigger a violent explosion. The ooze detonates in a 20-foot burst, dealing 2d10+13 fire damage (Reflex DC 16 half) to creatures within the radius, including those currently engulfed. The explosion can’t be prevented entirely, but the damage can be mitigated. If at least 30 points of cold damage are dealt to the ooze over the course of the encounter, the volatile chemicals cool and partially stabilize, making the final detonation instead deal only 1d10+13 fire damage (Reflex DC 16 half). Unstable Expansion (Ex) A detonation ooze is made of highly unstable chemical compounds that begin to break down as the ooze takes damage. As a reaction when a detonation ooze is reduced to 100 HP, its size increases to Huge. When it expands, it can attempt to engulf any Medium or smaller creature in the new squares it grows to occupy; it can't grow to occupy squares that are occupied by Large or larger creatures, and if there is no room for the ooze to expand, unstable expansion fails. The process repeats when the detonation ooze is reduced to 50 HP, except that its size increases to Gargantuan if it was already Huge, or Huge if it was still Large.
