@RiverMaiden 2 things!
1) As Cenco said, you gotta tone down the magic. Everyone is pretty weak at the beginning, but don't worry, we'll get stronger! So if you would, just add a little blurb about what they can do right now. Try using other sheets as a guide!
2) In order to have both darkness AND decay, your butterfly needs to be completely black. Also @Cenco wasn't there a 2 person limit on the darkness/decay and light/healing people? Obviously we can't enforce it now since we never mentioned it but I remember that being one of Inkd's rules.
Aside from that, looks good.
EDIT: After reading the OPC, I remembered something. She's a caster, correct? I'd see the tentacle being more of a combat class thing. You're allowed to mix the two classes, but doing so weakens them both. Just a heads up! (If I'm understanding this wrong, please tell me)
Yes, there was a limit of 2 for decay, and 2 for healing. I thought of that when looking over the sheet, but Callum's magic is different enough from the other decay characters that I didn't feel it was that big of a deal. The guidelines for magic is really vague, which let's everyone get creative with how they'll use it, so having 3 decays is okay by me.
And as
@RiverMaiden mentioned above, I agree that the Callum and Zilla fall under Caster rather than Combat. As I understand it, the tentacles are basically magical constructs -- so they're basically a 'spell' that's out constantly, which feels like a Caster thing, since what defines Combat characters is that they primarily use their body to fight, so punches, kicks, elbows, and knees.
