Firefern

Actions

Poison Spray (Recharge 5-6). The firefern exhales gas in a 15-foot cone. The effect of this gas depends on enviroment, see regional effects. The gas lingers in its original shape harmlessly for 1d4 turns, and can be ignited to instantly do 1d8 of fire damage and ignite any object not being worn or carried, destroying the gas. Each creature in that area must make a DC 12 dexterity save to take half damage.   Bite. Melee Weapon Attack: reach 5 ft., one target. To-hit and damage depend on enviroment, see regional effects. If the firefern had advantage on the attack roll, it may steal any item not being worn or carried as a bonus action, and makes a Dexterity (Sleight of Hand) check for it.   Pilot Flame. The firefern exhales a small flame towards one entity within melee range as a bonus action. This flame is to small to do damage, but it ignites targeted object if flamable.
