Mid battle skill change

[unknown-77]

Hi, I was wondering how I can change skills in the middle of battle? Like if An actor uses one skill under a certain condition that skill would change into a completely different skill. For example: If you use a fire spell and then you have a wind weapon equipped the skill would then become a lighting spell instead and you'd use that instead. or something similar to that. Thank you in advance.

You can make it add a state which seals that skill and adds the new one..

Or if its weapon based, you can make the weapon seal the old skill and add the new ones.
