Reyna is a tactical leader role. Her glove, commander glove, can both buff allies and debuff enemies.
Her main gun though is her pistol that you use with the right trigger/left mouse and it deals physical damage as expected.
Her commander glove is used with the left trigger/right mouse and shoots a slower projectile that removes shields.
Her abilities from GI
Overwatch – This support-focused ability allows Reyna to emit a charge from her Command Glove that automatically targets a nearby teammate and provides them with an overshield. This is especially useful for characters who have smaller shields, or no shields at all, like Thorn.
Priority Target – Similar to Overwatch, Priority Target sends out a charge from Reyna’s glove, only this one seeks out an enemy. Once hit, a percentage of all the damage dealt to that foe will bypass their shield for a short period of time, regardless of whether Reyna or another teammate is doling out the pain. As you can probably surmise, this ability would be wasted on a character like Thorn.
Rally The Troops – Reyna’s passive ability increases her movement speed for every shot she lands on an enemy with her pistol. This effect is stackable and also buffs nearby teammates, giving them an incentive to stick close to their commander.
Nick Of Time – Reyna’s abilities and upgrades revolve around helping out her fellow teammates, and Nick of Time ensures she’s always in the right place at the right time. The ultimate ability allows her to instantly warp to any ally’s location. In addition to supporting a teammate in need, Nick of Time also gives Reyna an exit strategy should she run into trouble of her own.
Like miko we have another support character but it looks like reyna can be in the mix quite a bit more. She will be another target but between her UA and passive ability she might be hard to nail down.
