Empowered might

You increase you Sacrificial Might by being able to add an additional 1d10 damage to yourself boosting your strength stat by +3 (6) This now can be used as a bonus action rather then regular action. (This 1d10 must come from yourself whether you have blood or not) Depending on what your 1d4 rolled you must make an Saving throw with disadvantage with that stat rolled. DC of 15+ saves.

If failed you gain additional -3 to the stat rolled for the pervious stat rolled for the 1d4

Your stat increase ignores stat cap
