They can't carry as many creatures as the original wyverns can, but that's really the only significant difference, and they're perfect for stealing wyvern eggs. A high level one will take less damage than a griffin, fly faster than a snow owl, and have more stamina than a pteranodon. I also use mine to kill alpha raptors and carnos for loot and xp.
More Crystal Wyvern Utility Tips
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 :( )
