Leveling Abilities

Is there a way that when an ability is learned/level I can sense it and set a variable accordingly.

If not, is there a way I can tell the skill level of a certain ability?

Condiction:
Interger Comparisen;
(Level of XSkill for (XUnit)) Equal to XLevel

Just to add to this, can you tell which slot an item is in?

FT... make a separate thread for that.
