Green Keeper

Green Keeper is an enemy from Final Fantasy Dimensions appearing in the Cave to Yggdrasil and Yggdrasil.

Battle
The Green Keeper is fought three times. Once in the Cave to Yggrasil and twice inside Yggdrasil (in the Underground level and in the Upper level). All its attacks are the same but they get progressively stronger, dealing more damage with physical attacks and healing itself for more HP.

Strategy
The Green Keeper can be defeated with continuous physical attacks but magic should be avoided because it will always counter it with Osmose. At some point it will cast Haste on itself. It's best to just keep attacking in order to make up for its Natural Healing.
