The crown is not bad but would be a lot better with CtC Frost Nova. Perfect enhanced defense for the level is 65%.
The shield is not too good. Pallies will use the paladin specific shields, amazons and assassins will want base DTM on their shields (and assassins will likely want to stick with bone shields). A throw barb could use it if he uses non-eth tspears, they'd likely prefer DTM base as well though, however it wouldn't be as important for them I guess. Necro uses shrunken heads, sorc would want base DTM again. Melee druid would use Pelta I guess for the FBR.
