A very simple question. Under what situation will the 'event - A unit Learns a skill' run? If a unit has passive skill and then he cast mirror image, it will trigger this event?
When the hero has a point remaining, he can go into the Learn Skills menu and choose a new skill to learn. When he chooses one, it will fire this event, and you will have the Triggering Unit (Learning Hero) as well as the Learned ability event responses.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
