Sorry if this is the wrong place I'm obviously new haha.
I recently picked up Sacred 2 and with it's size and rather lack of tutorial somethings are rather confusing, I was reading about the Zealous Doppleganger in the wiki and came across this line: "Keeping him as a spell will allow memorizing significant ZD runes number, increasing his combat values without any penalty"
Which raises a question, I under stand that getting runes and using them increases a skills level (and ZD runes means Zealous Doppleganger runes) what I don't understand is it saying the runes will increase his combat values without any penalty if you keep him as a combat spell rather then turn him into a buff (permanent).
So to clarify my question is this: do the buffs recieve a penalty past a certain amoun of runes that the combat cast spells don't?
