On_Equip casting mode

Created by: Ithirul

Is your feature request related to a problem? Please describe.

I am trying to run skills after a full set of items has been equipped. For example, a skill that makes you glow purple during night, and white during day. Another example would be a set that passively damages mobs around the player. The possibilities are endless really. However, with the casting modes available right now, such thing is not possible, since I would have to click a button or be attacked for that skill to run.

Describe the solution you'd like

An on-equip casting mode that is used like the other casting modes.
