I read somewhere that if you're wielding a barbed bow and use barbed trap, then bleeding caused by the trap last 33% longer. But if you're wielding a staff with +20% vs demons would the traps laid do +20% damage to demons or does it only apply to damage caused by attacks?
damage mods on weapons only apply to attacks with that weapon, nothing else. However, thinks like lengthen bleeeding, cripple, poison, etc. DO affect traps.
