Gundyr was once a champion like the Ashen One, but when he arrived at Firelink Shrine to assume his duty, it was too late; his Fire Keeper was long dead and the flame had already faded. When he was defeated by an unknown warrior, he became a sheath to the Coiled Sword to test future champions as the Iudex Gundyr, Judge of Ash.
The battle will commence once the player approaches him. Champion Gundyr fights in a similar manner to his present self, although he is far more aggressive, hits harder, and has a larger moveset that covers a wider area, leaving very little openings for the player to attack.
All moves he shares with Iudex have been enhanced in some way. For example, when he slams his halberd into the ground, he does this in an attack that consists of two stages, the first when he slams the weapon and the second when he raises it again, in another attack that has slightly more reach.
Two of the most noticeable attacks added to his repertoire are a round-back kick he performs if he detects the player is next to him after finishing a combo, and a shoulder bash that practically teleports him from any place within the arena to the player's position, knocking them back while dealing medium damage.
In his second phase, he will become even more aggressive and will start using some devastating combos and juggles. All of his attacks are then enhanced in one way or another and he can chain combos almost immediately, harassing the player without taking breaks while performing wide swings and punches. He also resorts to his back-round kicks and shoulder bashes more often and is able to reach the player's current position from all across the arena in just an instant.
However, perhaps his most dangerous enhancement is being able to perform counter-combos. He has a few powerful combos designed to trigger if he finishes one and detects the player is attempting to attack at that moment.
Gundyr can be parried and riposted, greatly trivializing an otherwise difficult fight.
The fight will start as soon as Gundyr is approached in his arena. He is vulnerable from the first moment and the player should take this opportunity to score as many hits as possible. It's not recommended to rush at him for this purpose, though, and instead conserve as much stamina as possible for when the battle properly starts.
Gundyr's most distinctive characteristic is his ability to dominate the immediate area around him. He has a vast repertoire of wide attacks and backward counter moves, and can also close the distance to the player in an instant. The main problem in this fight is Gundyr's excellent tracking, which allows him to unleash all of his attacks almost with perfect accuracy at the player, even if they roll away or are standing right behind him.
In his first phase, Gundyr will attack much like his previous incarnation, although his moves will now be faster, his combos longer, and he will try to perform his grab attack more frequently. Additionally, he will sometimes delay the finishing attack of some of his combos to trick the player into rolling early and ensure they get hit.
In his second phase, however, things will become much more complicated, with Gundyr unleashing very damaging - almost infinite - combos and chasing the player non-stop. Trying to stay in his vicinity is very risky. What the player is advised to wait until he starts performing a combo and run away as far from him as possible. When Gundyr tries to reach the player again, he may perform one of his two jumping attacks (the shorter consists of two hits), where the player may score a hit or two while he recovers.
Players should also be very cautious of not letting themselves be caught by Gundyr's juggle attack, which may outright kill them instantly if they are not careful.
Gundyr will react immediately if he detects the player is trying to heal and will cancel any combo or attack to quickly lunge at the player and stab them with his halberd. To heal, try to do so while standing behind him after evading his attacks and just after he is finishing a combo. Another method is to gain as much distance from him as possible and heal while he is performing a combo; however, since he will cancel it and rush to attack, the player should consider this and make sure they will have enough time to finish the healing process before he arrives to their position.
- Sword Master: If the player has defeated him at the Firelink Shrine, the Sword Master can be summoned for this fight. His summon sign can be found at the entrance to the arena, to the right.
Soul of Champion Gundyr
- Can be parried and riposted.
- Summons may get stuck in the large coffin in the back of the map.
- If any summon is stuck in the large coffin and Gundyr targets them, he may fall under the map and be defeated.
- If the player is killed by Gundyr, he may immediately run to the exit of his arena and attempt to escape through the fog wall. This is most likely due to him targetting the Black Knights on the other side.
