ESO added three new skins, but they are only available through Crown Crates

From time to time ESO adds new skins to the game that the players can use for their characters. Sometimes the skins are obtainable through quests, dungeon completion or trial completion. However, sometimes they also drop exclusively in the Crown Store or within Crown Crates.

The three new skins came with the new Crown Crate Season Wraithtide:

Magmaheart Skin

Brineglow Skin

Shallowbay Nereid Skin
