Lumin Paragon: 3rd-Level Encounter Powers

Dazzling blast is a controller-ish close blast power. It's deliberately pegged to be not as good as the 3rd-level wizard encounter power color spray, although it's more selective with respect to its targets.

Radiant bolts is a striker-ish ranged attack that focuses on dealing damage. Since the healing surge augmentation increases the damage dealt to each target instead of the damage dealt by each attack, it moderates the amount of damage that this power can deal to a single target.
