Boss: Knight of the Greatsword

The culmination of your efforts within Castle Ensis will lead to a confrontation with the formidable Knight of the Greatsword. This boss is a master of heavy weaponry, wielding a colossal greatsword with devastating reach and impact.

Boss Strategy: Knight of the Greatsword

Weaknesses: The Knight of the Greatsword is susceptible to Frostbite and Scarlet Rot buildup. Exploiting these status effects can significantly shorten the fight. Its attack patterns, while powerful, are often telegraphed, allowing for well-timed dodges.
Recommended Loadouts: Weapons with good reach and quick attack chains are beneficial for punishing openings. Consider a loadout that allows for rapid status effect application. Spells or incantations that can create distance or interrupt attacks can also be invaluable.
Key Attacks to Watch For:
- Greatsword Swings: Wide, sweeping attacks that cover a large area. Dodge *into* the swings to get closer to the boss.
- Stomp Attack: A ground-shattering stomp that can stagger players. Jump attacks can often avoid the initial impact.
- Charge Attack: The Knight will often charge forward with its greatsword. This is a prime opportunity to dodge to the side and counter-attack.
- AoE Slam: A powerful overhead slam that creates a shockwave. Sprint away or dodge through it at the last second.
Combat Tips: Stay mobile and don't get greedy with your attacks. Focus on dodging and finding small windows to strike. Guard counters can be effective against some of its less aggressive swings, but be mindful of stamina.

Key Rewards

Upon successfully defeating the Knight of the Greatsword, players will be rewarded with a significant item that aids in their journey through the Shadow Realm.

Greatsword of the Knight: A powerful new Greatsword weapon that scales well with Strength and Dexterity, featuring a unique Ash of War.
Knight's Greatsword Ashes: A unique Remembrance that can be exchanged with Enia at the Roundtable Hold for a powerful weapon or spell.

In addition to the boss rewards, thorough exploration of Castle Ensis will yield valuable items such as Runes, crafting materials, and potentially a Scadutree Fragment or a Revered Spirit Ash, which are crucial for enhancing your character's power and your Spirit Ashes.
