Act 2 Normal or Hell difficulty Defensive mercenary will provide Defiance aura. Act 2 NM difficulty one will provide Holy Freeze. The mercenary won't automatically turn the aura on, he will only do so when he needs to choose an attack. Let him kill stuff and he will activate his aura in a bit. As mercenaries level up, the chances they will activate the aura goes down. --- I play D2:LoD OFFLINE. Spellcheck is a gift, embrace it!
Thanks a lot. I guess he just didn't turn it on yet. So does the chances of him turning it on only increase if I level him up, or is it basically just the higher the level, the better the chance? (For example, if I purchase one at a high level later instead of leveling up the same one.) --- www.rpgdreamersforum.com
As your mercenary levels, the chances of him activating the aura decrease.
"Act 2 Merc Aura Activation
Act 2 Merc aura's do not automatically activate when you hire them, or do they become active when you leave town. The Desert Warrior requires a little stimulus to use his aura and this means getting him involved in the action.
Basically, the Act II merc will only activate his aura when he has to pick an attack. The chance of activating his aura decreases every level up, to around 2.5% at lvl90+. So if your character kills everything before the merc gets a look in, the aura won't activate.
It can be a little more complicated than what is stated above and there do seem to be instances where a hired mercs aura will simply not turn on, or at least take a very long time to do so. Simply returning to town and then letting your merc kill more monsters should normally solve such problems."
