@Bob: Thanks a lot!

You first explaination did work.
My plan it to make an enemy switch sides and fight for the heros against the enemies. I'm using the transmogrification to change the picture.
Before:
After:
There is now one attack called summon, it's element is summon, it withh change the enemy in a friendly earth-element-monster.
I still want to be able to summon/turn more elemental monsters (fire moster ), I guess i'll need to make an summon attack with the specific element - for example summon(Fire) - for each element-monster, as there seems to be no easy way to do this.
There are many options in many menus to be considered, and sometimes I feel like there are options missing or maybe I did not see them.
So, if you know how to make this in an easier way or if there is wiki-tutorial any help is welcome!
