Redeemer is good for fast/no farm and budget setup, the dmg drop from AP isn’t that big, again it’s a minmax thing, so for peak max potential you want something else, otherwise its fine, it’s been used before by others before/for a long time
Crittrain had a setup with it too
Banana used it in his levelling guide/budget BM
etc etc
