Overall
Oku is a retaliatory tank built around Thorned Volition — a resource that accumulates every time he takes a hit, scaling with the attacker's power. Every skill he uses expends a portion of this stored charge as bonus damage on top of its base hit, then partially replenishes what was spent. The natural decay of Thorned Volition converts into self-healing, and skill expenditure also heals him, making the resource double as both offense and sustain. His taunt forces enemies to feed him more charge while he takes heavily reduced damage during its window. His ultimate punishes shielded or control-immune enemies with massively increased damage and knocks them to the battlefield edge. His beetle companion strips Tenacity with each multi-hit combo. As he accumulates Thorned Volition, he permanently reduces all incoming damage, and if enemies stun or debuff him, he reflects those same effects back.
