You evoke the greater powers of good, and your beard stiffens, turning metallic and reaching halfway down your chest, giving you greater protection.

Your beard grows and turns to pure and magically hardened silver, providing you with a +2 sacred bonus to AC. If you do not have a beard, you grow one for the duration of this spell (even if you are a creature that cannot normally grow a beard, such as an elf or a female human). You get a +2 circumstance bonus on Diplomacy checks against dwarves.
