Torchlight III · Dusk Mage Light skill
Holy Bolt
Holy Bolt fires a ranged bolt for weapon damage, with later listed bonuses for every third cast and Harmonic Form.
How it works
The class guide lists Holy Bolt as an active Light skill costing 2 Mana and dealing 250% weapon damage. At skill level 3, every third cast fires a larger bolt that deals 50% more damage. Level 6 adds 20% Light Skill damage, and level 10 fires two Holy Bolts while in Harmonic Form. The passage does not state a cooldown.
