Heya, this is already looking very good! I like the idea of the parasite. A creepy addition to a Norm. I’m not very well experienced here myself, but I played some RPGs and stuff. So I guess, harvesting power means something like a stereotype of Mana Pool the character would have. A Power he leeches from, or a drains life or anything.
And for the clericon i think weakening means, he decreases some of the enemies abilities, like strength, armor or stuff. But how this looks and how you explain it works, is left wide open i think!
I looking forward for the next updates!
One thing, as the rules say no mix, I’m a bit concerned that the parasite would be regarded as “physicly” connected to the clericon, which would make him a mixed char. But also this could be some kind of magical artefact, weapon or armor… so, the rules are a bit vague to me here too…
