Time energy radiates from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centered on you. Each non-hostile creature in the aura (including you) gains a +1 bonus to their AC, reduces damaged done to them an amount equal to your spell casting modifier, and has advantage on death saving throws.
