Jagged Peak is a tiny region with big bosses in Elden Ring Shadow of the Erdtree. The area is located east of Scadu Atlus and Gravesite Plain. You will find four bosses in this mini region.
The area isn’t as big as Gravesite Plain which has 13 bosses.
Jagged Peak Drake
The first Jagged Peak Drake is seen right after you exit the Dragon’s Pit dungeon. Head straight into the water, where you’ll spot multiple dragon corpses and a sleeping dragon in the center of the lake.
Attacking this dragon will trigger the boss battle. The Jagged Peak Drake uses both fire and lightning attacks. To effectively combat it, stay on Torrent and focus your strikes on its legs. Defeating this drake rewards you with a dragon heart and Dragonscale Flesh.
Dueling Jagged Peak Drake
Just past the Foot of the Jagged Peak Site of Grace, located up the mountain path, you’ll find two Jagged Peak Drakes locked in combat.
Rather than engaging both at once, it’s wiser to wait for one to defeat the other. Once the battle is decided, take on the remaining drake.
For defeating the victor, you’ll earn a Dragon Heart and more Dragonscale Flesh.
Ancient Dragon Senessax
Continue up the path from the Foot of the Jagged Peak Site of Grace, past the area where the Dueling Jagged Peak Drakes fought, and you’ll find Ancient Dragon Senessax resting in a cave.
This massive dragon attacks with red lightning. The best strategy is to ride Torrent and attack its tail to inflict damage safely.
Upon defeating Senessax, you’ll receive an Ancient Dragon Smithing Stone and a Somber Ancient Dragon Smithing Stone.
Bayle The Dread
To face Bayle the Dread, follow the path up Jagged Peak past the Dueling Jagged Peak Drakes, Ancient Dragon Senessax, and through the lightning storm.
You’ll eventually reach the Jagged Peak Summit Site of Grace, right before Bayle’s boss fight arena.
Bayle is tough, but the battle can be made easier with the help of Igon, an NPC who can fight alongside you and provide additional loot.
Defeating Bayle rewards you with the Heart of Bayle.
