The druid is sneaking through the camp site and a few soldiers start walking towards her general direction.

Druid: Uhhh I TURN INTO A TREE.

DM: The camp you’re sneaking through is in an open field.

Druid Player: Shit.

Soldier: Has that tree always been there?

Druid: I’ve been here for weeks!

DM: Roll bluff.

Druid Player: Crit.

Soldier: Well the tree would know better than us I suppose!
