# Inferno *Generic Hazard* Whenever an uncontrolled fire spreads, it can create an inferno that quickly engulfs creatures, objects, and vegetation. An inferno consists of at least four contiguous 10-foot [Cubes](/Rules/Source/variant-rules/cube-area-of-effect-xphb.md) of fire. Each of the inferno's 10-foot Cubes can be doused with 10 gallons of water. Exposure to a strong wind for 1 minute causes the inferno to grow, adding `dice:1d4|noform|noparens|avg` (`1d4`) new 10-foot Cubes to its volume. An inferno deprived of fuel burns itself out after `dice:1d10|noform|noparens|avg` (`1d10`) minutes. An inferno damages any vegetation or object that isn't being worn or carried that it touches, dealing `dice:4d10|noform|noparens|avg|text(22)` (`4d10`) Fire damage immediately and again at the end of each minute. Any creature that enters the inferno for the first time on a turn or starts its turn there takes `dice:4d10|noform|noparens|avg|text(22)` (`4d10`) Fire damage and is burning. *Source: Dungeon Master's Guide (2024) p. 76*
