Absorb Chaos is a spell created by Daina, the Dark Sorceress after she delved into the lower levels of the Great Chasm of Magic. The atmosphere was polluted and heavy with chaotic energies far greater than she'd ever dealt with. She created this spell to protect herself when diving into further depths; however, over the years, the true nature of the spell changed. Daina always worked alone. When she made her first friend down in the Great Chasm, she adjusted this spell to accommodate them. 

When you or a creature you can see within 30 ft receives damage from a spell or magical effect, you and up to four other creatures within 30 ft manipulate the chaos around you to allow all creatures targeted by the spell to gain the resistances of all other creatures targeted this way for the duration. You and creatures targeted by this spell cannot share resistances granted by spell effects or magic items.  

At higher levels - When you cast this spell using a higher-level spell slot, the number of creatures that can be affected by this increases by one for every spell level beyond the 5th.
