Winter's Mount

( Frostburn, p. 50)

[General]

Your special mount is native to the frostfell.

Prerequisite

Special mount ability,

Benefit

Your special mount gains the cold subtype. It gains immunity to cold, but has vulnerability to fi re, which means it takes half again as much (+50%) damage as normal from fi re, regardless of whether a saving throw is allowed, or if the save is a success or failure. Your special mount is also hardier than a nonfrostfell version; it gains a +2 racial bonus to Constitution.
