Some numbers for those interested in potentially breeding these guys; Melee mutations have a gain of 11.8%~ per, Health of 392.5 per, and stamina of 32.5 per. From playing with Blood Wyverns their lifeleech on their breath attack is tied to their health stat and not their melee stat, capping out at 35 healing per second at 10k or better health. Their lifeleech based on eating corpses however is 50% of their bite force (not affected by mate boost bonus but it is boosted by trained melee stat). For numbers of what stat capped looks like (254 points so training is available), health sits at 50k~ before imprint, melee at 1580%~ before imprint.
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 :( )
