Sadly I don't own a hell reaper, so I did all calculations with coryn club. According to those Hell Reaper can now do more damage (~10%) than player crafted halbs (only non elemental ofc) while maintaining more crit rate (~115 with lv. 7 food) and more MP (~2300 with Lv. 7 food, yes 2300 is useful because gsw reduces max MP by 300). I can share the equipment I used for the calculations later, I am only on mobile right now.
