Talk:Radiating Orb (Condition)
Find stacking Radiating Orb is very strong in combat. I'll document sources of it for posterity and in case anyone else finds this useful or can suggest more:
Coruscation Ring combined with Guiding Light on a Magic Missile spamming mage (using Gale for this with the Psychic Spark necklace for +1 Missile) gives a ton of stacks per cast.
Luminous Gloves apply Radiating Orb when dealing radiant damage, equipped on a Paladin with The Blood of Lathander and the Holy Lance Helm, gives multiple stacks per turn. Lots of undead miss when blinded and misses trigger the Helmet reprisal effect. You can also get more radiant damage on every attack with the Lathander's Light buff doing d4 radiant damage on every attack as well as the Smites paladin gives.
Back these up with Bane from a debuffing cleric or the crossbow Harold and most bosses can't touch you.
