Cosmo — Detailed Guide
Cosmo is a small jumping spider that came to ASA in 2024 with the Steampunk content of Bob's Tall Tales. It works as a living grappling hook: its webs let you swing, pull yourself in and cross gaps, and it rides on your shoulder between uses.
Where to find it
It is an uncommon spawn on Aberration, Valguero, Genesis: Part 1 and Astraeos in ASA.
Taming
- Method: a passive, non-violent tame. It is skittish, so approach carefully.
- Food:
Chitin is enough, and
Plant Species Z Seed, its preferred food, gives much more progress. - Signals: move in and feed it while it glows green. Stand still while it glows red, or it shoots charged webs and runs.
Breeding
It lays eggs that hatch in about 1 hour 26 minutes at 4 to 12 °C. A baby takes about 3.9 days to mature at 1x.
Uses
- Movement: swing mode with web lines you can pull in, reel and release.
- Combat: shooter mode fires web balls that slow targets.
- Aberration: it glows when
Nameless are near, and its Charge Infused Webs strip the armor of light-weak creatures such as Nameless and
Reapers.
Tips
Equip it through the
Cosmo Wrist-Shooter. Its carried weight counts as half while it sits on your shoulder, and a glider suit or parachute makes web travel much safer.
