Very Rare, Requires Attunement
Description
Granted for service to Vanalir and her Mistress, the Codex Aetheris is a much coveted spellbook. Crafted within its pages are secrets to Graviturgy magic, allowing even the unitiated Wizard to learn its power. It serves as a spellbook and spell focus for a wizard, granting +2 to spell saves DCs and spell attack bonuses.
But there is an odd celestial magic to it as well...when a celestial evocation wizard is in Revelation and chooses to sculpt a spell, they can forego the extra damage they would usually deal. As a bonus action, they can instead allow up to a number of allies equal to half their proficiency bonus that they chose to sculpt to spell around to regain hit points equal to their proficiency bonus. This ability can be used up to twice per long rest.
