Probably asked before... (Morphing)

... but I just searched for 5+ minutes and couldn't find a thread on this sooooooo:

I have a skill where a character morphs and he acquires mana degeneration while morphed. When he hits 0, guess what? He is forced to morph back!... only the problem is I can't seem how to figure out how to do this without a timer checking his energy every second.

Any other way besides a timer to do this?

Only way I know of--that doesn't use timers--is World Editor Unlimited which has an event called "Event Unit State".

Honestly timers wouldn't be that difficult to code or take up alot of processing, even in GUI.

WEU works fine, I just don't know what units to put, since it needs to be multi-instanceable. (This is the only type of unit on the map with energy anyways.)

timer or periodic event is the only way to do this

WEU has a method to detect the energy, just I'm not sure which unit variable stuff to use. Help would be great =)
