My thinking is, you only have to do the quest using your summon once, but then once you do, the skill is given to every summon after that.
Quest: Summon must kill 1 Raknoc, then you give one Raknoc eyeball
I think that the fact that the summon has to be the one to kill the creature is both new, and challenging!
The Raknoc eyeball is just bc...well, we need some use for all those raknoc eyeballs that we've all got jumbling up our inventories! :-p
