There are 3 variants of the crystal wyvern. The tropical one gets the hydrated buff( more damage, resistance etc) when standing in water like a spino. Even though it gets the buff in water it can’t swim and is found in the white shores area. The blood one breath steals the life force and heals while using it breath attack and is found in the forest with the red trees. The ember crystal wyvern is found in emberfall. It’s breath is more precise and can go further than the normal fire wyvern breath. The breath also has a rage meter with the more you use it the more damage it does. Eventually it will start to get blue flames in the mix. Hoped that helped you
Crystal wyvern easy passive tame. If server allows, run onto its back between the shoulders and feed it crystal in your last slot with [e]. On it's shoulders it will be less likely to drop you. Carry food and drink, have a flyer on follow if you can, and parachutes just in case.
For everyone wondering you must be a level 65 in order to tame these with either crystal or prime crystal. The way to get prime crystal is by knocking a crystal wyvern then pushing triangle or Y in order to get the prime.
If you are farming out taming crystal wyverns to get on their backs its much easier to mount your current wyvern and walk up to the wild wyvern and dismount yiur wyvern and use its neck as a bridge to get onto the wild wyverns back.
U can get the primal cristal by knocking them, once u knock them just pick it up from their back.
Best way to tame is to jump on its back and feed it, u'll get a free ride and an easy tame ( take a parachute in case )
Just figured this out: Heir Wyvern eggs hatch into normal variants of crystal Wyverns, but the level of the eggs relates to “taming effectiveness” when you tame a normal passive tame Wyvern. So, a 225 egg would be the equivalent of a 150 crystal Wyvern with a 100% perfect tame. I’ve found 195 eggs that hatch with 9,445 HP (official servers) and 358 Melee, but not all eggs have “better” stat rolls, it seems random but I’m researching it further. My technique was to build a large cage trap, steal the eggs then fly the parents back to the trap where I thin them out (and heal my blood Wyvern) by draining them of HP until 2 remained, then tranq them out one at a time and take their crystals, then finish them off, head to base to incubate the egg, then run off and passive tame a high level with my 15 crystals. Doing this brought in high level, high stat Wyverns for breed stock.
