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 :( )
Yes there are baby’s that you can breed to get but also they only eat primal crystal and watch out when shooting the crystal wyvern, because other crystal wyverns nearby will attack you. The best way to knock one would be to make a trap with behemoth gates and there was a bug, I’m not sure if there still is but if you go out of render, the wyvern will teleport out of the trap
Here is a tip that most know, hop on its back and feed it that way, and just hope it does not run into a tree. Primal crystals work the best for taming them and you get them from knocking crystal wyverns, the baby only eat primal crystal
To get Primal Crystals, you must knock out a Crystal Wyvern and harvest Primal Crystals off their back. Once you’ve harvested once, it’ll take about an hour for the Crystal Wyvern to "recharge" and allow you to harvest more.
The number of Primal Crystals that you can harvest from a Crystal Wyvern increases with its level. A level 1 produces 2 Crystals, and it increases by 2 at roughly every 7 or 8 levels.
The Crystal Wyvern has an extremely high torpor depletion rate — one of the highest in the game — so it will not remain knocked out for long. You might consider trapping it in a cage so that you can harvest it again later.
