Spring Drakeling buffs

Aspect Of Spring: +1% / +15 health regen, -10% stamina consumption

Native Biome Boost: +10% XP and +10% loot quality

Draconic Knowledge(if on your shoulder): "Drakelings store a percentage of experience while mounted. Can be used to boost another creatures experience, with higher value boosts also granting a 'Dragon Hoard Key'."
