Foe to frog is a 5th-level wizard daily attack power. It transforms a creature into a Tiny beast, dazes it, and restricts its actions to moving or shifting. Foe to frog's effect ends if the creature takes damage. On a hit, foe to frog loses its one-turn duration and instead ends on a save.[HotF:94]
A version of foe to frog called slimy transmutation appeared in the Red Box, as a level 1 daily power.
