Laguz Unit work

Laguz Basics
The introduction of Laguz units into Fire Emblem Heroes required the addition of several odd mechanics, clarifications, and rule and effect change to accommodate their relative complexity.

Class References and Symbology
Laguz are introduced into the game via weapon types, similarly to dragons/manaketes. There are 3 classes of Laguz, each its own distinct weapon type and symbol: Beast, Bird, and Dragon. Skills that reference "Laguz" reference all 3. The symbol of each has a box with an emphasized border/outline and a central item in it, either a cat's head, two wings (of different shape than the flier symbol) and a bird's head and long neck, or a dragon's head, respectively. That central item extends past the boundary of the box in the upper right corner. Within the border in the bottom left corner, there is an "L" etched.

Laguz units are all colorless. Weapons like Raven tomes now specifically exclude Laguz units, or specifically mention it when they do include Laguz units.

Transformation Mechanics
There are 3 Laguz states: Un-transformed, Transformed, and the in-battle "transition" from the latter to the former, Exhausted. Laguz transform prior to, during, or after battle, depending on circumstance. The transformation status of Laguz is documented using the new 2-Counter Charge system of specials.

When a Laguz unit is transformed, the symbol used is not the charged/ready symbol of other specials, but rather a T. Thus, usually a transformed Laguz will see something like this with their special: ~_~_.

Laguz units all use infantry movement as the base movement. Their weapons convey movement changes in the un-transformed state and/or the transformed state. Weapons like Poison Dagger now often specifically exclude one or both classes of un-transformed and transformed Laguz. Skills like Infantry Pulse may or may not exclude Laguz as well.

Exhausted State
Some skills specify that the un-Transformed state is synonymous with the Exhausted state, other state that any post-combat un-Transformed state is synonymous with the Exhausted state.

Herons
Herons are an assisting class of Bird Laguz

Galdrar is a skill that combines the refresh ability of Sing and Dance with Laguz mechanics. Sing and Dance themselves now specifically mention that they cannot be used on units with a Sing, Dance, or Galdrar skill. This incidentally prevents these skills not only from being used on Herons, but also on units with special Sing, Dance, or Galdrar skills. (Special singers and dancers with boosted assist skills are also on this wiki, see _, _, or this category page.)

Incidentally, each Heron itself has a special Galdrar skill that it can use.

Miscellaneous
Exhausted state is technically one of the few status conditions present in Fire Emblem Heroes that amounts to more than just a stat buff/debuff. Certain odd skills can transfer this status to non-Laguz units, and certain odd skills penalize this status.

Certain skills outside of a countering capacity relate to Laguz but don't have to be borne by them. Laguz Aid is an assist that helps desirably maintain the transformation of Laguz units.
