Prerequisite: Small or Tiny Size*

• You can move into a space occupied by an ally of at least one size category larger than you, and they don't count as difficult terrain.

• You can end your turn in a larger ally's space (but only one creature can hide in this way in an ally's space).

• You can take the Hide action to hide inside a larger ally's space.

• If the you or the ally moves or you otherwise reveal yourself, you are no longer hidden.

*Halflings, gnomes, goblins, and kobolds are always small. Aasimar, changelings, constructs, genasi, and tieflings can be small or medium.
