need a triggerer for a little help

I need a triggerer to help me with a hero upgrade type function which upgrades the hero from one type to another but keeping its level, attributes, skill levels, name, etc.

Pm me if you can help, thanks.

Why not use just an ability that switches the hero, but keeping its abilities, like chemical rage and the like?

Its an upgrade the user does... which upgrades his hero to a stronger one.

I tried berserker upgrade, etc. but nothing works.

A permanent metamorphasis would work, just set the duration to 0 and it will never end.

I spent forever trying to figure that one myself. I have heroes that upgrade many times into stronger units. so this is what I am using each upgrade. they are going to a specific location to do so. . . .I am a newbie triggerer tho.

Heres what i got. it might help it might not. I didnt keep skills and levels tho but maybe u can work off of it.

Vexorian helped me out and found a simple way. Create a chaos ability and set the unit to the new unit, and then using triggers give the ability to the unit being upgraded. Works like a charm.
