The Shield Knight is the guardian of Blue Protocol’s battlefields — a defensive powerhouse that uses precise timing and strong shields to absorb damage, control enemies, and protect allies from lethal attacks.
If the Heavy Guardian is a pure tank, the Shield Knight adds mobility and tactical defense, combining counter-based gameplay with support auras.
