Location: Heide's Tower of Flame
Strategy: The Dragonrider is a relatively simple boss. Before the fight, activate the two pressure plates in the arena to expand the platform, preventing him from knocking you off. Stay close to him, circle strafe to his shield side, and attack after his combos. Be wary of his shield bash and spear thrusts. He is susceptible to Magic damage. Summoning Masterless Glencour can provide a distraction.
