Acelin the Stalwart is a Legendary Spirit champion from the Banner Lords faction with a Defense role. His entire kit revolves around Shields: Behold the Banner spreads defensive coverage across the team, and the passive Knight of Knights amplifies that protection by reducing incoming damage for shielded allies. Shield Shatter then turns accumulated Shields into team-wide healing before converting them into offensive pressure. He is typically run as a protective tank in Shield-stacking compositions, valued in Arena for soaking burst damage and in Banner Lords Faction Wars. His output scales directly with his HP total, making an HP- and Defense-focused gear set essential to unlocking his full potential.
