Ok I can help if you have a crystal blood wyvern with all leveled hp well just so happens spit your special attack on a giga while your blood wyvern is still recovering from hp also keep away from giga all costs and then just watch your blood wyverns hp go up high I havnt tried it yet but I know it good
way for getting him hp
Tropical wyverns spawn near the beach and have a water buff, like the spino, blood wyverns spawn in the forest that has red trees and also the red trees can give charcoal and blood wyverns can drain life from other creatures/ tames/ people and give your blood wyvern health if it is hurt at all. Ember crystal wyverns just breathe fire, blood and ember crystal wyverns are better for pvp. I recommend, if you have it, use the bone wyvern skin so they can’t tell what type of crystal wyvern it is. Good luck on taming them! (I play on Xbox so I can’t tame them :( )
