I was wondering if Iron Ram Hauberk is that much better than ACP body, or I could get other things like Patronus Ring or Rose Strap for SAM.
NQ Coral Scalemail is a cheap, servicable body piece for Magic Damage reduction. Unless you can cap your MDR without a body piece, the Coral should be on par with IR Hauberk. If you CAN cap your MDR without a body piece, then the IR body becomes more attractive.
If you already have +5 Enmity on an ACP body, then IR won't be much of an upgrade in the enmity department.
I don't have an ACP body for Pld, so I picked up my Iron Ram Hauberk as soon as I logged in after last update. Function x 2 + Fashion = Win!
