In the .entity files, Abilities usually call buffs which have an effect inside the game.
Buffs can call other buffs.
I think that if a buff-call line can trigger not only buffs, but also Abilities, it will allow for more flexible interactions. Stuff like Targets would have to be forwarded to the called Ability and such, but it would be nice.
This way we could have combo-abilities which could be casted at once and upgraded individually.
