A Loot Box is an item which, once opened, will award a player with items by chance. A loot box will always give a player the item that is guaranteed, but the second item is completely random.

Wording is En Masse loot boxes goes something like: "Box is guaranteed to give a Semi-Enigmatic Scroll, and it may give the costume item you actually wanted." SeanDynamite killed costumes loot boxes when he became TERA Product Manager on En Masse. After that boxes give the you costume you wanted, instead of useless consumable.

Gameforge afaik never made loot boxes for costumes, or least never made them tradeable between players at least.

Loot Boxes currently exist for mounts: Dragons, Drakes, Dinomounts, Shibas, new Gryphons, Phoenixes, Frost Monarch. In game, loot boxes are marked with prefix "Surprise Box:" in trade broker.

Since february 2022 change these boxes give tokens Ancient Mighty Bones, so when you've opened enough, you're guaranteed to get the mount.

There are some other sources of RNG 'thou. GF does not directly sell all the pets in game, instead you buy a box and get a random pet, which you can trade with other players. Same goes with some costumes and weapon skins.

Most costumes in game are only in sale for a limited time and are in Wheel of Jackpots in TERA Store. You roll a wheel of fortune and get a random reward, which may be something you wanted. If it was not, you can sell it to other players.
