Benefit
In cold areas (temperature at or below 40° F), creatures native to cold environments and creatures with the cold subtype summoned by you are more powerful and agile than normal. The summoned creatures gain a +4 enhancement bonus to Strength and Dexterity for the duration of the spell that summoned them. In areas of extreme cold (below -20° F), any summoned creature affected by this feat has maximum hit points when summoned.
