Weird Dance is learned by several monster companions such as the Goodybag. MP reduced is 1~2, being the weakest of it's skill group. This set the standard for all monster versions of the skill.
Weird Dance is learned by advancing to either rank 3 of the Dancer vocation or rank 4 of the Merchant vocation. In this installment the skill received the same upgrade as Drain Magic, meaning that magic absorbed is the user's level/4 +5.
Weird Dance is learned at rank 3 of the Dancer vocation in the PS1 and 3DS versions of the game. In the original it uses the level-based calculations as in VI, but in the remake it merely drains 5~12 MP regardless of level.
Used as a dance by certain enemies like the Bag o' laughs.
Enemy bag o' laughs are capable of using Weird Dance in battle. When used, they will project a magical field surrounding them that will drain the MP of any character that happens to be caught within.
