Chibi-Gasbag

One pet, two spellings

This chibi-pet goes by Chibi-Gasbag in ARK: Survival Evolved and Chibi-Gasbags in ARK: Survival Ascended. The ARK Wiki keeps the singular form, which it says is how the game spells the item, and notes Chibi-Gasbags as the more expected spelling. Whatever the name, the item text describes what it does: "Earn XP from Alpha creature kills when equipped, to increase its level and earn additional max-levels for your Survivor!"

An Extinction requirement

According to the wiki, a player must own Extinction to equip this chibi. Our records place it on Extinction and Lost Colony. The wiki ties it to ARK: Winter Wonderland 4, says it has been available in every event since, and gives 304.1 as the version that added it.

How the levels work

With the pet equipped, kills of certain predators feed it experience. It can level up five times, and every level-up permanently lifts the maximum level of the survivor wearing it by 1, for at most 5 extra levels. Among the creatures that count in both games are the Alpha Deathworm, Alpha Karkinos, Alpha Raptor, Alpha Skeletal Raptor and Enraged Corrupted Rex. Steam players in ASE also have targets like the Alpha Chrysaora, while ASA adds creatures such as the Astral Mammoth and the Enraged Lightning Triceratops.

Slot, loot and weight

ASA has a Chibi slot for it, while ASE players put it in the off-hand slot; on a mount it rides in the survivor's lap. It is an item rather than an unlocked skin: it drops on death and is lost unless the survivor gets that inventory back. Our records list 3 crate types that can contain it, the Valentine's Fishing Items and Fishing Meat crates and the Raptor Claus Gift. It weighs 0 and stacks to 1.
