I'm looking at using the Mythic Rules published so far to give my players a bit of a boost (the party consists of a ninja, samurai and witch) and would like feedback on the following feat for the Witch:
Extra Hex (Mythic):
Prerequisites: Extra Hex, 1st Mythic Tier
Benefit: Whenever you could select a mythic spell, you may instead select an extra hex known. Additionally you may expend one use of mythic power to activate a hex as a swift action.
Due the campaign they will gain both levels and mythic tier at suitable plot points.
