Sword off Baron, SoD has a 2.5 sword with 26 ap and “equip: drains target for 2 shadow dmg every 1 sec and transfer it to the caster, lasts for 30 seconds.”
This effect is not triggering, nothing in combat log, no buff or debuff on enemy. Probably not working at all.
Edit: after further investigation, this sword’s drain proc does work BUT only works when you EQUIP the sword in melee range of your hostile target. Equipping it mid combat is the only way to get the drain to work.
