Veteran of the Watch

One Against Them All. The veteran counts as four creatures of challenge rating 3 for the purpose of encounter building, and rolls for initiative four times, acting on each turn. When the veteran is reduced to 0 hit points, their lowest place on the initiative order is removed, they regain the use of their legendary resistance, and their hit points return to maximum, unless they have no more places on the initiative order left.

Legendary Resistance (1/Day). If the veteran fails a saving throw, it can choose to succeed instead.
