This is the "tutorial boss" for Dark Souls 3. He must be fought to access Firelink Shrine, which means the player cannot level before defeating him.
This boss fight is mandatory.
Strong Sweep: he will sweep his halberd in front of him. The attack is delayed, so delay your roll so you aren't caught out.
Jump and Smash: when the player is too far from him, he will jump forward and smash his halberd at the player's position.
Fast Sweep: similar to Strong Sweep but faster. Used as a recovery move.
Jump and Pierce: similar to Jump and Smash, but he will pierce the ground rather than smash it. Recovery from this move is slow, so use it as a opportunity to attack.
Rapid Slice: slices the ground in front of him quickly, multiple times. Used as a follower from Jump and Smash.
Upon dropping below 50% health, Iudex Gundyr will mutate into a dark, serpentine creature, with a massive claw and tail. He will attack with both of his appendages, which greatly extend his reach.
Sweep: he will use his tail to sweep across the arena. Get behind him to avoid the sweep.
Overhead Smash: he will jump towards the player and smash his tail down. Dodge to the side to avoid this.
As the first boss of the game, blocking is a poor strategy due to the player's lack of Stamina early on. Dodging through his sweeping attacks will greatly increase your odds of success. He is parryable during his first phase.
For his second phase, it is best to roll forward through his sweeping attacks, avoiding his grab and utilising invincibility frames to survive.
Keep at a distance and attack during his recovery phases. During his second phase be careful of his extended reach.
Using Firebombs or similar fire consumables will help deal damage to him during his second phase.
- Must be defeated before the player can reach Firelink Shrine and to receive the Coiled Sword, the item allowing instanteous travel between bonfires.
- "Iudex" is Latin for "Judge."
- His armor set bears a strong resemblence to Old King Dorian from Demon Souls.
- His crown is similar to that worn by Ludleth of Courland.
