behavior:
if you hit a target with an arrow while holding an melee weapon that has any of the mob_effect affixes, the effects of those mob effect affixes will be applied in addition to any mob effect affixes of a ranged weapon in the offhand

expected behavior:
that melee weapons apply their benefits when you use them to stab things, rather than merely when something gets hurt while you are holding them, or at the very least for one item's mob effects to apply but not the other (preferably the ranged weapon)

(not sure if this would go in apothic attributes or apotheosis itself)

This is a bit weird, though consistent with how vanilla applies things. I can probably make melee weapons only trigger on direct attacks and not run the logic for indirect ones.

worth mentioning that the bug is also fun to mess around with, i just wanted to make sure you're aware of the behaviour
