Liechi Berry

Raises Attack in a pinch.

Liechi Berry activates when your HP falls below 25%, raising your Attack by one stage! It's gone after use but can give you the boost you need in a tight spot.

This berry works well on physical attackers that can take a hit or two. It's also good with Substitute if you think about it since you can wear yourself down to activate the berry while still being protected. Compared to the Choice Band, you get flexibility but less raw power.
