Volatile Reagents

COMPLEX HAZARD 2

Description Potion bottles, alembics, and potent ingredients violently explode when jostled and accidentally combined.

Disable Three DC 20 Acrobatics or DC 20 Crafting checks to sort and separate the bottles of volatile ingredients into groups

AC 18; Fort +10, Ref +8
HP 10 (BT 5); Immunities critical hits, precision

Explosive Catalyst
Trigger Slick drinks Gattlebee's growth serum

Effect The giant lizard bumps into lab tables and workbenches, causing dangerous ingredients to intermix and detonate. The hazard rolls initiative.
Routine (1 action) A random 10-foot square in Gattlebee's laboratory explodes, dealing 2d6 damage to creatures and objects in the area (DC 18 basic Reflex). The damage type is randomly determined each round: acid, cold, electricity, fire, slashing, or sonic.
Reset The lab contains enough ingredients for this hazard to last 1 minute before all materials are expended. Alternatively, the hazard resets once Slick shrinks to regular size.
