I would suggest gaining Miasma, Bane and Fester from the soon-to-be-defunct Shadowbringers SMN and using Fester as the new Energy Drain. 100 potency with no dots on your target, 200 potency for one dot, 300 potency for two. Would be a major upgrade in DPS life for SCH and gets rid of Energy Drain which is even more underwhelming in Endwalker.
