Changing Damage Type

[tacotorch]

Ok im working on a arena map and i want to make it so the players can buy an item to change their damage type from hero to chaos. Ive tried using a trigger to give them a metamorphisis ability when they buy the item but the problem is i dont want their model or range changing. Is there a way to trigger this without metamorphisis?

 

[Numerion]

just make metamorphosis with model of changed unit=your hero(or make for each hero own metamorphosis
and then make
trigger1
event:
unit acquires item
condition:
item being acquired equal to your item
triggering unit equal to your hero1
action:
add metamorphosis to triggering unit

make this trigger for all your heroes

trigger2
event:
unit drops item
condition:
droped item equal to your item
action:
remove metamorphosis from triggering unit

there is maybe another way how to do it but i dont know it
