How to beat King Arthur in SWORN
The main Arthur fight is two phases. The dragon is a bonus phase that v1.2 moved into Boss Rush. Morgana is a different boss reached with Lancelot’s gems, not Arthur’s third health bar.
Phase one and phase two
Community fight notes and the boss-order video describe the first phase as Lord of Camelot: sword strings, vertical light pillars, and a grid of projectiles. The second phase is the Grail-Corrupted Tyrant: fire on the floor, tracking dragon-head shots, a sweeping laser, and spider adds. Those names are how players talk about the moves. They are not an official move list, and no source prints phase health or damage.
I would rather leave the numbers blank than copy a percentage from a single clip. If a video shows a health gate, that is one recording.
The bonus phase people search for
Searchers asking for a bonus final phase usually mean one of two fights. Dragon Arthur is the extra form. From Update 2 on 24 March 2026, the official notes place that dragon in Boss Rush. Before v1.2, posts disagreed: some said Boss Rush, some said three gems, some said a high difficulty. I do not collapse those into one old trigger.
The other “final” is Morgana. Collecting three gems and beating Arthur sends the run into an extra arena. That is a new boss, documented in the same video’s last chapter, not a third Arthur phase. Beating Morgana is described by players as bragging rights rather than a Steam achievement.
What to bring
ProGameGuides, writing about v1.2, points Sovereign runs at control rather than pure damage. The build pages that match that sentence are the Shatter frost plan, the Monk Chimes row, and any ranged or damage-over-time setup on the weapon tier list. Five difficulty achievements exist: Squire, Knight, Baron, Duke and Sovereign. Each is a clear of the game at that rank, not an Arthur-only trophy.
Fandom’s King Arthur article is a single line calling him the final boss. I do not use it as the source for phases.
FAQ
How many phases does King Arthur have?
Two in the main fight. Dragon Arthur is an extra phase that, since v1.2, shows up in Boss Rush. Morgana is a separate boss.
How do you trigger the dragon?
On the current patch, Boss Rush. Older triggers are in conflict across posts, so they are not listed as fact.
