PM me any questions you have, I don't mind :)
During the Tundra event you need to buy charged sticks, so start saving silver. Best way to do this is by adopting or buying animals that can do quests.
You can make charged sticks with granite. Only a lightning-strike roc can make charged sticks.
You use the charged sticks to make portal energy cells. For this you need adamantine, so try to get some now.
You use portal energy cells to go through the green portals on the Tundra biome. Each portal uses one cell and takes you one level higher. The higher the level, the harder it is to defeat monsters.
On level 8 and higher, wild etelia appear. You have to defeat them to get a crystalline ice. You need 20 crystalline ice to hatch one etelia. There's other stuff you need to hatch etelia, like a lykos with Ice breath and Ice aura, three liquid deviants (you need to extract this from deviants during the event, so buy a couple while they're still cheap!) and pure snow. Pure snow is literally the easiest thing to get on the tundra, so don't stress about that.
You find your pristine snowflake on level 10 or above.
My advice is get some pets that have elemental attacks with elemental resistance or robust scales. Otherwise the wild etelia will defeat you too easily.
Musical larynx, Magic horn, and Ice aura don't work on etelia.
It's nice to have venomous skin or napalm or something to lower their hitpoints even more, but sometimes even that doesn't help. Sometimes they have magic mirror!
Whoever calls on the name of the Lord shall be saved.
