does venom work on traps (are traps a weapon)
Depends on the trap. The light and fire traps do not work with venom, but Blade Sentinel, Fury and Shield do work with venom.
Only the following bonuses are applied, in all their variations (Based on Character Level, % Enhanced Maximum Damage, Against Demons/Undead) and regardless of source:
- Magic Damage, Fire Damage, Lightning Damage, Cold Damage and Poison Damage
