Forest Fire
COMPLEX HAZARD 4 -10
A 10‑foot‑by‑10‑foot bonfire spreads to the surrounding forest on each of its turns.
A successful DC 22 Athletics, DC 22 Nature, or DC 22 Survival check from an adjacent square is sufficient to smother one 5‑foot‑square of fire; each attempt is an Interact action. Dousing the flames automatically extinguishes one or more sections of fire, with no check. Water typically clears a 5‑foot square if the amount is small (such as from a spell like create water or hydraulic push). Larger amounts of water, such as a full bucket, typically douse a 10‑foot‑by‑10‑foot area (or 4 squares in some other shape). Throwing a bucket of water on flames requires an Interact action. A waterskin doesn't contain enough water to put out even 1 square of fire. Cold can also put out fire, but only if the cold can affect an area; cold is less effective than water, so a frost vial puts out only 1 square of fire, and a ray of frost is ineffective.

A brimorak urges the fire to spread out of control
The bonfire becomes a forest fire and rolls initiative.
On its turn, the fire spreads into a number of additional squares equal to half the number of squares the fire currently occupies (minimum 1 square). You determine the squares the fire spreads into. Any creature that ends its turn next to the flames takes 2d8+5 fire damage, or 4d8+10 fire damage if it ended its turn within the flames (DC 25 basic Reflex in either case). A creature can take damage from the forest fire only once per round.
