Beast Unit

Not to be confused with Laguz.

Beast Unit is a designation certain classes have that mark them with a vulnerability to anti-beast weapons (e.g., Beast Killer).

Overview
A unit type currently exclusive to Fire Emblem Awakening and Fire Emblem Fates, the beast attribute is associated with any horse- or pegasi-mounted classes as well as certain shapeshifter classes.

Members of the horseback or pegasi-riding classes boast greater movement than infantry units. This grants them exceptional map presence as well as the ability to perform a variety of offensive or supportive functions (e.g., cleanup, shuttling). Members of the beast-like shapeshifter classes possess the exclusive ability to harness various stat boosts from Beaststone weapons and are able to traverse certain terrain tiles without any movement penalty. Perhaps as a balancing mechanic for these assets, the beast attribute can be exploited by certain weapons that deal effective damage against them.
