Kelsaik's Weapon Skin

Kelsaik's Weapon Skin is Weapon Skin available from Corrupted Skynest dungeon, added in February 2020 patch. This dungeon was closed in August 2021, so it's impossible to get the skins any more (unless it's reopened). In addition materials dropped in Partner adventures (materials are found in random loot box called Nightmare Kelsaik's Treasure).

There are two versions of the skin. One has fiery fumes effect and other frost fumes effect, reflecting the duality of Kelsaik. Fumes are even left behind when moving or riding a mount. Effect is probably coolest on classes that swing their weapons in wide circles, like Reaper.

To craft ice version of the skin you need: Design is from smart box Frostbite Kelsaik's Weapon Template Crate that gives template for a class who opened it.
 * 40 Chilling Frostbite Toenail (Left)
 * 80 Burning Ice Fragment
 * design (Frostbite Kelsaik's Template)

To craft fire version of the skin you need: Design is from smart box Hellfire Kelsaik's Weapon Template Crate that gives template for a class who opened it.
 * 40 Scorching Hellfire Toenail (Right)
 * 80 Burning Ice Fragment
 * design ( Hellfire Kelsaik's Template)

Ice Fragments go to bank, but Toenails do not. This was changed in December 2021 patch. If you still have materials on various characters you can make the skin.
