holy shield isn't an aura.
select HS, cast it, select conc aura and HS will stay active for quite a while (~7 mins or so)
the quote just means that you always want HS to be active, when it fades, simply recast it and then kill things for another ~7 mins. Without HS active your chance to block should fall right down from 75%.
Ahh I see. Thought of it as an combat skill like smite or something... So it works like frozen armor then =)
Another thing, when I place points in concentration my hammer damage doesn't increase. Just hit level 27 and placed one more point on concentration and it did absolutely nothing to my dmg (its like level 12 now btw). However when i switch of the concentration aura my dmg drops like hell (like it should). So why didnt the damage increase?
If you were in a party with another conc user, and their conc aura was a higher level than yours, then your Lying Character Screen (LCS) would have been showing your damage with their conc aura. So when you increased your conc aura by 1 then assuming the other persons aura was still higher (or equal to your new level) then the LCS won't change.
If you weren't in a party then i dunno, but the chances are that you hit level 27 in a baal run or somewhere in a party.
Actually I was not in a party... or yes I was but only with my friend who is playing a sorceres. It's the same thing with vigor. I have an amulet that gives +1 to defensive auras, and I should get a 14% dmg increase when I put it on since it adds points to Vigor which is a synergy but the dmg stays the same. Or doesnt it work that way?
