Reach Sol the Absolute

To reach Sol the Absolute the two Astral Challenges must be completed during the run, and Isaac must enter the Blue Chest. Alternatively, Sol can be found at the top of the Tower of Babel on Ascended difficulty.

Andromeda has the ability to transform regular challenge rooms into astral ones using Gravity Shift! (once per kind).

Mods with special interactions

Highly recommended but not required, without it mini-map icons won’t show properly.

Unlocks for beating Sol with Andromeda and T. Andromeda, plus a special Gravity Shift interaction in regular challenge rooms.

The stars are calling!

Bosses have custom icons and health bars
