there are 6 Resource Mythics. Blood Magic Set is considered a Resource just like Blood Magic Mythic is. you can only have one Resource on a Build at one time. if you have 2 or more Resources on your Build, only one will work and the other 2 are just taking up space doing nothing.
Blood Magic (Mythic & Set), Equivalence, Fury, Energy, Discordance, & Alchemy are the 6 Resources.
this was an idea I had awhile ago for making Blood Magic Set a little different from Blood Magic Mythic and usable with some other Mythic Resources.
