Ok this is what I have

common event parallel process
<>branch if taz leather armor equip
<>variable oper : [0009:armor] set,taz armor no. this is to keep the armor on
<>var. oper : [v[0008]] set, taz experience
*
<>change sprite association : taz hero 5-3
<>change class taz hero c , no level change, no skill change, no change in statistics
<>change face assoc. : taz new faceset-3
<>change equip: taz v[0009] equip
<>change exp. : taz exp. v[0008]add
*
the chara loses his exp with the new armor and will not gain new exp.
I try your way and same thing.
I have a new problem when the new armor is equip his sword is nolonger equip I tried to use
a var. oper where the stars are but I got event error.
