Chibi-Wyvern

A miniature wyvern that lifts your level cap

The Chibi-Wyvern is a Chibi-Pet in ARK: Survival Evolved and ARK: Survival Ascended. Chibis are mostly cosmetic, but they also bring a level cap increase, which the item text explains: "Earn XP from Alpha creature kills when equipped, to increase its level and earn additional max-levels for your Survivor!" The ARK Wiki notes that equipping this one requires owning the Scorched Earth DLC.

Wearing it

In ASE the pet goes into the off-hand slot, while ASA gives chibis a dedicated slot of their own. Once equipped, the wyvern stays at the survivor's front left and follows the way they move and face. On a mount it rides in the survivor's lap, and when the survivor lies in bed it sits close by.

Levelling the chibi

A chibi can level up five times, each time from kills of certain predators made while it is equipped. Every level permanently adds 1 to the maximum level of the survivor wearing the pet at that moment, for up to 5 extra levels in total. The wiki's list of creatures that give chibi XP includes the Alpha T-Rex, Alpha Raptor, Alpha Megalodon, Alpha Fire Wyvern and Enraged Corrupted Rex. Some are marked as exclusive: the Abyssal Alpha T-Rex and Alpha Water Wyvern to ASE on Steam, and the Astral Raptor, Alpha Ossidon and Enraged Lightning Rex to ASA.

Where it comes from

The wiki ties the Chibi-Wyvern to several ASE events: ARK: Love Evolved, ARK: Turkey Trial 4, ARK: Fear Evolved 4, ARK: Winter Wonderland 4 and ARK: Eggcellent Adventure 5. Our records add 2 loot sources, the Fishing Items (Valentine's) and Fishing Meat (Valentine's) crates. Chibis are ordinary items rather than unlockable skins: on death they drop with everything else the survivor carries, and they are lost unless the death cache is picked up again. The pet weighs 0 and stacks to 1.
