I've seen people claiming that only super low level wyverns can be tamed without primal crystals, but that simply isn't true.

All you have to do is jump on their back (can be done from the ground), center yourself up where the wings meet the neck, start pumping it full of regular old crystals, and enjoy the ride. I tamed 4 of them that way today, and not once did I get thrown off or have the progress bar start to drop.

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.

Lvl 1: 2 Primal Crystals

Lvl 10: 4

Lvl 20: 6

Lvl 30: 8

Lvl 40: 12

Lvl 50: 14

Lvl 100: 28

Lvl 150: 52

Lvl 200: 54

Lvl 300: 80

Lvl 400: 108

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.

Crystal isles is definitely the map for running drops! With one of these guys (preferably tropical because of their hydration when they hit the water which buffs their speed) you can get loads of good blueprints super easy by just flying around the map picking up all of the drops you see! Using this method I easily got loads and loads of amazing blueprints in just 1-2 hours, including a mastercraft crossbow blueprint and an ascendant flak chest blueprint, among loads of good saddle blueprints! Please spread.

Knockout:

1. Build a wyvern trap

2. Agro it and lead it into the trap

3. Knock it out with tracks and go up to it to grab the primal crystal

Taming:

1. Find a good wild wyvern

2. Use a grapple and shoot its neck

3. When you’re hooked on, start feeding it the primal crystal

4. You now know how to tame a 140 crystal wyvern in 10 minutes

There are two variations of Crystal Wyverns:

1) The Crystal Wyvern hier is a highly aggressive variety of Wyvern that spawns in that Wyvern cavern on the Isles, they are untameable but you can get primal crystals from them, they also spawn in the Wyvern Queen fight.

2) The standard Crystal Wyvern can spawn in the sky above areas that match their variety they can be tamed PASSIVELY with crystals and Primal crystals.

THESE MIGHT BE COMING TO MOBILE SOON!!!

Ultimate survivor is coming to mobile starting with the island and scorched (hehehe mobile players gonna have microraptors)

Probably not the until late 2025 though for this map but the game should be coming this year (2024)

if you want to tame a wyvern within the first couple hours of your playthrough I recommend doing easy island note runs, getting to level 65, going to crystal isles with atleast 200 weight to hold the reg crystals, make a metal hatchet, get atleast 110 crystals, hop on the back of a crystal wyvernt then going prone near the head, and just keep feeding it and your done! (for extra help I recommend getting parachutes, just incase you fall)
