I'm asking about daggers specifically due to vistani restrictions.
I've used barovian daggers from 10-20. With +5 and 3d6holy, 3d6 fire and undead bane on top. I can't outcraft it.
At 20 I see:
Sacrificial dagger, but this too, seems to have less average dps. Vampirism could be nice in non-reaper settings.
At 21:
Blade of the high priestess. I like the idea of paralyzing, but I worry that DC 25 won't do much. Wounding is pretty well nerfed due to stat regen. But! The slay living might be fun if it works.
crafted: +6, 2[1d4], 5d6 force or light, 5d10 bane. Better than barovian for anything you want to put a bane on. I'm looking at you Reapers (and oozes)!
At 23:
Agony... +8, 2.5[2d4] 3d8 bleed, 2d6 untyped, disintegrate, imp deception. Against anything that bleeds, I see this as the first clear winner over the level 10 barovian daggers.
At 24:
thunderforged options start.
What do you all like?
