Blizzard Servant — Winter's Advance

At 6th level, a winter child strengthens the bond between her and her companion, imbuing it with her own power. Her blizzard servant gains the following benefits: Medium size, +2 bonus to Strength, +4 bonus to Dexterity, +2 bonus to Constitution, and cold resistance 10. If the Winter Child already has an animal companion, it only receives half the bonuses and does not increase in size.
