Compared to other unique items, Doombringer's properties are actually quite straightforward.
With rather large added damage, Doombringer is great offensively and, unless an enemy is immune to physical damage, it dishes out consistent amounts of damage.
Doombringer doesn't just end at its offensive-oriented affixes, however. Defensively, Doombringer also offers a chance to cast Weaken, reducing damage taken to the hero. It also gives a very useful bonus to maximum Life. For physical fighters, who tend to have high Vitality, the maximum Life % works wondrously.
