So, before using a charge of Forged Metal Of Artifacts to enhance my super duper bow with Bloodwood for an added 16% Hit Life Leech and HPR2, I copied all the stuff to TC1 to try. The bow didn't had HLL in the first place, so there was no issue of stacking/non stacking the property, it just added it flawlessly. But then I actually TRIED the bow, and then came the bad surprise: Doing 100+ damage to a mob I still leech 0 Life, nada, not even 1 HP. The other leeches I had imbued (Mana and Stamina) work perfectly, just not the added Life Leech. Is this a known bug?
