Mercenary's "Doom" Giant Thresher

[Nicator]

If the item requirements aren't the problem, does the merc have any other items that are generating auras?

Nope, Stealskull (helm) and Gladiator's Bane (armor) come from 1.09. Of course, a Might mercenary has Might Aura, but that's as far as his versatility goes :)

I'm not very familliar with aura order, but do paladins have trouble with conflicting auras?

Not at all. The worst that can happen is, when several sources of the same aura, a lower slvl replacing a higher slvl aura every 3 (or 4, not sure) seconds.

Sorry I couldn't be more help...

Oh, don't be, you're giving me a hand after all. ;)
