It's probably too late to ask you to add this in if it's not already included, but are you going to have rules for how an Artifact increases in power?
One thing i was wondering: does it gain in power with each level up? or with each increase in Divine Rank? if it's each level, can you bank powers? for instance, if I'm a level 30, and i gain a level, that means that my artifacts gain power as well. but that's only a +1 or so. Can i wait till i've earned enough levels till i can add a Divine Ability?
Or do they work in a totally different fashion?
