History of Well of Radiance

Well of Radiance is the Super of the Dawnblade subclass's Attunement of Grace tree for Warlocks, introduced in Destiny 2: Forsaken. The Warlock thrusts a blade into the ground, creating a 3.5-meter pool that scorches nearby enemies. Guardians standing in it, including allies, gain healing, damage resistance and increased weapon damage, and are protected from Stasis effects. The Super also generates Orbs of Light.

Damage resistance inside the well has been adjusted over time, and it is lower against other Guardians than against enemies. Because it supports the whole fireteam, it is a staple in raids and endgame, including Crown of Sorrow.
