Shield AC for a caster

[starkind]

Yeah ac starts to suck anyway for casters post 35 as their skills are pretty much capped in sync with like lvl 20s mobs.

Still a great item and could mean the difference between dying in one round to a lvl 50 mob quadding or lasting two rounds and getting a heal, mob rooted and backing off.. boils a bit down to luck but the AC makes that luck possible.
