===Does OW from another player/hireling override the 1st OW?===

No. If another player or hireling hits a target that is under the influence of OW, the timer is reset to 8 seconds, but the life loss will still be that one calculated for the first player/hireling that hit it. That means, when your mercenary triggers OW on a monster which you already hit and triggered OW before, the timer will be reset to 8 seconds, but the monster will still receive the same damage it received from you triggering OW.

===Can OW be countered by replenish life or absorb?===
