Calofisteri (Final Fantasy V)

Calofisteri is a boss from Final Fantasy V that watches over the forest part of the Cleft of Dimension, she appears when the player presses the "switch" one of the trees located there.

Strategy
She uses Reflect quite a lot, either to reflect Bio, Poison, Stop and Old off her or to reflect Haste, Regen and Protect off you. She also has high defense, so you should focus on reflecting magic off yourself. She counterattacks with Drain so do not attack unless you're going to deal a substantial amount of damage.
