Tested out the Divine Intervention: Opulent Revival, and it does not appear to affect allies besides the cleric who casts it.
Text of ability reads: "Resurrect fallen companions with half their hit points, and restore all nearby allies as if they had Long Rested."
Testing this power (in a very late game spoilery battle), it fully restored Shadowheart (the caster), but had no effect on my nearby allies. All the allies were within the circle radius and in line of sight. Has anyone else tried this and encountered a similar issue?
