Does life steal work against ancients, by that I mean items with life leech mods or skills with life leech properties. In that same venue, do mercs deal reduce damage against ancients? Lastly much defense should one have if one decides to wield a big 2-hander weapon long enough to lifesteal and tank the ancients? Also in the same venue, how much health should one shoot for assuming one wants to do hell ancients on hardcore... untwinked... in a single-pass? Thanks in advance.
