"0.30.2.1 - Module 1 Patch 4 - Release Patch!"
Cleric
Clerics have two new spells at level 4, Blessing of Smiting and Hymn of Smiting. These buffs allow the cleric to sanctify the weapons of their group, causing them to occasionally channel holy power into their strikes.
Blessing of Smiting blesses a single ally for 35 minutes. While it's active, their melee and ranged attacks have a chance to strike with Sanctified Weapon, dealing Holy damage to their target. Hymn of Smiting grants the same blessing to your whole group with one cast.
Sanctified Weapon grows stronger as the blessed ally gains levels. The two blessings don't stack with each other, so use whichever fits the moment.
Can only presume this will be more on the level of the conjured hammer holy damage than the cleric's own orbital strikes. Neat.
