Sylph of Life as buffer tho is the worst. We don't know all details of Maid of Life ressurection mechanics (not like Jane developed her powers a lot) but. All stats of SoL are suddenly outlandish. They HEAL AND DON"T DIE. Oh and the worst - they can "buff" the bacteria in your guts. You know, the ones who would cause you a painfull death if they ever manage to get to blood. Fear the healer pjs. They are scary.
I mean, don’t think of it in Jane terms, Jane has her own interpretation of the Maid of Life. A Buffing Sylph of Life could assist the group to Make and Improve Agency, letting them go through with their plans by holding back the enemy, or ensuring they can pull off whatever tactic they’re trying to. They could also Buff Life as in, accelerate the body’s natural healing capabilities, or enhancing biological functions to strengthen themselves and others. Never say ‘X would be the worst’, you never know when you will be facing against one of them. ;p
