IMPORTANT TIP!!! First of all, Tropical Crystal Wyverns get boosts (like spinos) when they get in water (but they still can’t swim). Second of all, Ember Wyverns shoot fire and they fuel a sort of rage meter that after a while of landing hits with the fire, they shoot blue fire and their stats are greatly increased. Lastly, the Blood Wyvern is the deadliest and have a blood attack that if it lands, they steal health from the aftermath bleed damage. Hope this helps!
