They can make ice bridges.

So first you have to toggle skills to the ice bridge, and then activate it and build as you would build a structure. Take caution, as when you build a bridge the old one disappears. This could also be useful to defend from rival players, as you could run up a bridge and make a new one so the old one disappears, rendering the enemies’ melee useless. The bridge ability also has a short cooldown. Also, you will never fall whilst building a bridge because the base is always under you. You can walk off a bridge AFTER building it, though, so be careful.

If you taxidermy them they’ll look like a cryptid.

Can slide, self healing ability that last like 2 seconds, damage increase ability that gives it increased damage on the next hit, ice cone ability that does good damage, can climb up walls, and the final ability is an ice bridge that you can build mid air with and you can place an ice bridge on another and so on to have an infinite path but you can only have one ice bridge placed at a time.

Solywyn:

Feed a Veilwyn vulpite to gain this lighter fully grown version of the tame.

Provides protection from the cold, it can create bridges made out of ice for traversal and can climb sheer cliffs. Utilises an advanced healing factor to heal both itself and the rider and has an ability that allows it to empower its next strike using cryokineses with a surge of strength and speed.

Hey guys, just found out how to 100% Veilwyn buff "Adventure!".

- Veilwyn companion mode

- cryo sickness 2 baby carcha

- unclaim them

- kill them with your weapon (they take A LOT MORE dmg when cryo sickness) not your dino

- BAM 100%

not sure of its a glitch or not, but using the Solwyns Ice Bridge ability, you can basically fly by placing one bridge on another at the end of the first.
