A unit equipped with at least one of the skills below will have an additional action option called Rally.
Awakening & Fates
Upon activation, all Rally Skills on that user will activate, granting stat boost to all allies within a 3-tile (2 or 4 in Fates) radius of the user. This command will end that unit's turn after they activate the Rally Command.
A unit may have multiple Rally skills equipped and all will activate once the Rally Command is used. Thus, a unit with Rally Speed, Rally Magic, and Rally Defense will boost Speed, Magic, and Defense upon activation. Multiple units may activate separate Rally Skills and still have the compounded effect. However Rally Skills do not stack upon themselves. Therefore if two units activate Rally Speed in the same area, all allies in the range of both will only get +4 Speed, not +8. Rally Spectrum and Rally Heart's stat boost do stack on other Rally Skills's individual stat boosts. This gives a maximum of +14 to Luck, +2 to Movement, and +10 to all other stats if all 10 Rally Skills are used simultaneously on one unit.
Rally is a separate command in battle and allows a unit with at least one Rally skill to give a stat boost to one ally. Rally skills are tied to Authority and certain characters learn Rally skills as their Authority improves. If a unit has multiple Rally skills equipped, they will apply all applicable ones when the Rally command is used.
A unit equipped with any Rally skill equipped in their Support Skill slot will be able to interact with an single ally. Upon doing so, they will apply their Rally boost to said ally unless the ally has visible buffs that exceed the total of the stat boost their rally skill would provide.
