Replace unit?? abilities??

I wanted to create an action that would replace a unit with another one, but it would still keep the same spells and it would have a new imported weapon.


I was thinking.

Event - Unit reaches level 5
Condition - Unit is BlaBla
Action - Replace abilities/unit??
??? attach "sword" to hand? of Triggering unit

Oh yeah and the unit is an acolyte ( or a peasant if acoloyte wont work)

Uhh kind of confusing request but try replace unit with unit, then use the trigger add ability to last replaced unit. Then under special effect create the special effect on the unit.
