Cosmo is an unreleased creature in Ark Survival Ascended. It is expected to appear on the upcoming Aberration map. Cosmo is a shoulder-mounted spider that is scared of players and will run away when it sees them. A tamed Cosmo can:

1. Scare off enemy creatures with its light.

2. Replace the grappling hook and possibly move like a Bloodstalker (though this is uncertain).

3. Dance.

Overall, it’s a good replacement for Sinomacrops, as they have very similar abilities. This information may not be accurate, as the spider is not yet released. The tentative release date is September 4, 2024.
