Grants Atk+3. Enables【Canto (２)】during turns 1 through 4. If unit initiates combat or is not adjacent to an ally, inflicts Atk/Res-6 on foe during combat and unit makes a guaranteed follow-up attack.
After an attack, Assist skill, or structure destruction, unit can move ２ space(s).
(Unit moves according to movement type. Once per turn. Cannot attack or assist. Only highest value applied. Does not stack. After moving, if a skill that grants another action would be triggered (like with Galeforce), Canto will trigger after the granted action. Unit's base movement has no effect on movement granted. Cannot warp (using skills like Wings of Mercy) a distance greater than ２ space(s).)
In Norse Mythology, Brokkr is a dwarf and the brother of Eitri who helped him forge Draupnir, Gullinbursti, and Mjölnir. While Eitri used magic to forge the weapons, Brokkr would work the bellows so the fire would be hot enough for the magic. The name Brokkr also means "the one who works with metal fragments; blacksmith."
- Similar to how Breidablik is said to resemble weapons of the real world (mainly a pistol), Grim Brokkr also resembles a real world weapon (specifically a shotgun). It's possible Eitri based her weapon based on the former's design.
