just another way multiclassing gets the shaft.
I thought the downside was losing out on pre's now they are adding in the ToD nerf whats next.
I think it should have NO save and be based on levels of monk with a cap like the heal spell such and such per level max xxx for somewhere between level 12-14.
at 9 you get the 250 negative energy maybe giving 50 per monk level after that till it caps at 400 at 12 or 500 at 14 this way there is still some scaling but doesn't invalidate multiclassing since it has it's own drawbacks. ie lower unarmed damage no top tier pre no 10dr at 20 no qp.
