Rune Arm

Rune Arm (or Arm Cannon) is new kind of equipment implemented with Update 11 and the Artificer class. It goes into secondary weapon/off hand slot and requires Artificer Rune Arm Use feat (class feat) to use.

How it works

 * Can be worn together with 1 handed weapons and crossbows (not bows)
 * Tapping the Alt button will start charging it up, tapping it again fires it.
 * You can use the rune arm use feat on your actionbar to make it keep autocharging.
 * Damage will be affected by Artificer level and charge tier.
 * Rune Arms will give a bonus elemental damage to the weapon in your main hand.
 * Prevents you from blocking.
