Elden Ring Shadow of the Erdtree Bayle Boss Guide: Jagged Peak Preparation

Bayle the Dread waits in a crater at the top of Jagged Peak, and he's arguably the meanest optional boss in Shadow of the Erdtree. Somewhere north of 40,000 HP, heavy resistance to every element, and a second phase that turns the whole arena into a hazard map. The climb to reach him is its own little boss rush of drakes, too. The good news? The road there hands you the tools to win, including one very loud man with a greatbow who's waited his whole broken life for this fight.

Reaching Jagged Peak

Getting through Dragon's Pit

The trip starts at the Castle Front grace in Gravesite Plain. Ride southeast and take the road that climbs the cliff face up to Pillar Path Waypoint. You'll hear the next step before you see it, because there's a man screaming in the dirt on the road just south of that grace. That's Igon. Talk to him and exhaust his dialogue now, since that kicks off the quest you'll want finished before the boss.

From the waypoint, follow the path southwest and a hostile Ancient Dragon-Man invades you along the way. The cave entrance sits behind him, marked with torches. That's the Dragon's Pit, and it's the only door into Jagged Peak.

The pit is a cave of skeletons and a Lesser Magma Wyrm, with some solid loot tucked into it (an Ancient Dragon Smithing Stone, among other things). The confusing part comes at the end. You reach a huge dark hole with a message beside it: "Be brave, show no fear." The game means it. Jump in. The fall looks lethal but won't kill you.

Boss mist waits at the bottom. Behind it is the Ancient Dragon-Man again, this time swinging the Dragon-Hunter's Great Katana. Beating him drops that very katana, and it comes with a built-in anti-dragon effect. So the game basically hands you a dragon-slaying weapon one region before the dragon capital. Take the big double doors past his arena to the Dragon's Pit Terminus grace and you're through.

The climb to the summit

Head east out of the terminus past a lone Jagged Peak Drake (sprint by on Torrent if you'd rather skip it), follow the cliff path around, ride the Spiritspring up, cross the bridge, and you land at the Foot of the Jagged Peak grace. From there it's one long line up the mountain:

The basin lake holds a sleeping Jagged Peak Drake. It has to die to open the way forward.
South of the lake lies a colossal dragon corpse. That's the Grand Altar of Dragon Communion, complete with a priestess and its own grace. This becomes your home base for the region.
Back at the basin, go east over the rope bridge. Two drakes wait there. Only one has a boss health bar, but the other won't leave when its buddy dies, so finish both before moving on.
The route up runs through two more Spiritsprings, a tunnel that rolls boulders at you, and Ancient Dragon Senessax. She's optional, but she drops an Ancient Dragon Smithing Stone and a Somber Ancient Dragon Smithing Stone. Hard to say no to that.
Past her you'll find the Jagged Peak Mountainside grace, a trail of dragon corpses, a pitch-dark cave full of electric slimes, and a final Spiritspring that pops you out at Jagged Peak Summit.

Through the stone arch is the crater. Walk in and the old dragon wakes up.

Prep before you drop in

Bayle is a stats wall as much as a skill check, so a little shopping pays off. Game8's suggested baseline is rune level 170+ with a Scadutree Blessing at +13 or higher, and between the two the blessing matters more. It's flat damage dealt and taken, and fragments are scattered all over the southern map anyway.

For your weapon, bring something that stabs. His absorption is 35 against physical, 40 against every element, and just 10 against pierce, so spears, great spears, and thrusting swords get the most done. Dragonslayer gear works too. The Dragon-Hunter's Great Katana you just looted qualifies, and fextralife's top armament pick is the Dragon King's Cragblade from Placidusax's remembrance.

Coat whatever you carry. Dragon Communion Grease adds 38% damage against regular dragons (28% against ancient ones, per the wiki) and lasts a short while. The recipe comes from Igon's Cookbook [1], costs one Knot Resin and one Sharp Gravel Stone per pot, and you can loot ready-made grease off the dragon corpses around the mountain. The base-game Dragonwound Grease is the weaker cousin at +30% and +20% for 60 seconds.

On defense, run Flamedrake Talisman +3 and Boltdrake Talisman +3 together, because his breaths hit as a fire and lightning mix. Flame, Protect Me stacks on top of both. And grab the Map: Southern Shore if you haven't, so the region actually shows on your map.

Igons Quest and Summon

So who is this guy? A battlefield scavenger who ate dragon hearts, took the Drake Warrior path, challenged Bayle, and got absolutely wrecked. Now his limbs don't work and he hates that dragon with everything he has left. His quest is short and almost all of it happens on the road you're already walking:

Find Igon on the road south of Pillar Path Waypoint and exhaust his dialogue. You'll pass him on the way to the pit, so there's no extra trip.
Clear the Dragon's Pit and reach the Foot of the Jagged Peak. The sleeping drake in the basin has to go.
Visit the Grand Altar and talk to the Dragon Communion Priestess. Choose to devour the draconic essence and she hands you an Ancient Dragon's Blessing, a one-use consumable that bumps all damage negation by 15% for 70 seconds at the cost of some FP. Genuinely useful for the boss. Ask her about Igon and Bayle too, since she explains the whole feud and how Bayle wounded the old Dragonlord.
Kill the drake duo east of the basin, over the rope bridge.
Igon appears near that arena once the duo is dead. If you can't find him by ear (his voice carries, to put it mildly), open your map and look for the NPC marker. Talk to him and he gives you Igon's Furled Finger, the key item that makes his summon sign show up at all.
Climb to the summit, start the fight, and summon him.
After the win, warp back to the foot of the mountain. His body rests where you left him, and you can loot Igon's Greatbow, his full set (Helm, Armor, Gauntlets, Loincloth), and Igon's Bell Bearing. Give the bearing to the Twin Maiden Husks at the Roundtable Hold and they'll stock Igon's Harpoon greatarrows.

One branch to know about before you climb: the priestess has her own storyline. If you give her Thiollier's Concoction at night, a delivery chain that starts with Moore and Thiollier back near Belurat, her ending changes and so do her rewards. More on that at the bottom.

The summon itself is a steal. His gold sign appears once the fight actually starts, on the left as you enter the crater, and only while you're carrying the Furled Finger. He doesn't count against your co-op player slots, he doesn't add a single point of HP to Bayle, and you can still bring a spirit ash on top of him. He parks at range and fires greatarrows for the whole fight, does real damage, and pulls the boss's attention now and then.

He also screams the entire time. Lines like "Curse you, Bayle!" and "Behold, a true drake warrior! And I, Igon! Your fears made flesh!" with a promised "hail of harpoons." His actor, Richard Charles Lintern, described the recording as going from naught to 5,000, and it shows. Even if you're a solo-purist sort of player, summon him at least once. It's the best audio in the DLC.

Reading Bayles Attacks

First, the numbers, because they shape everything else. Bayle has 41,612 HP on a first playthrough, 120 stance, and no parrying, though he does take a critical after you break his stance. He deals standard, fire, and lightning damage. Absorptions sit at 35 physical, 40 across every element, and 10 pierce. Stack that with his weakness to dragon-type damage and the plan writes itself: a piercing weapon slicked with anti-dragon grease, or a dedicated dragonslayer armament.

Status effects are mostly a dead end. Bleed, poison, rot, and frost all need 745 buildup for the first proc, and he's flat immune to sleep and madness. A cold-infused pierce build still gets something out of chill procs, more or less, but don't rebuild your character around it.

Where to hit him

Bayle's body is a map of his backstory. He jumped Dragonlord Placidusax ages ago, they mauled each other to a standstill, and it shows. His entire left leg is gone, most of both wings is gone, and two of Placidusax's severed heads are still clamped onto his neck, biting down forever. Grim, but useful: the head, the leg stump, and the exposed bone at the wing stump all take 50% bonus damage.

He props himself up on his wings since he lost that leg, so he fights hunched and lower to the ground than most dragons. That makes him awkward to slip under, and the wings can block your angles, so come at the leg stump from the front or the side. One small mercy: as of patch 1.12.3 his tail has no hitbox at all, so it can't clip you while you work the back leg.

Phase 1 move list

Two habits carry phase 1. First, the camera: lock-on only grabs his head, and he moves so much that the lock will fight you when he crowds in. Lock for spells and arrows, then unlock when you go in for the leg and free-aim your pokes. Second, the rhythm: his quick claw strings aren't worth punishing, while the big commitments (breaths, the leap, the grab) leave long openings. Bait the grab when you can, since that orange mouth-glow telegraph is generous and the head is right there waiting after a whiff.

It's an attrition fight, plain and simple. Casters should know their damage is getting shaved by 40% off the top, so slow, heavy spells like Comet Azur fit best during his long channels, and Great Glintstone Shard does steady work the rest of the time.

Surviving the Second Phase

At roughly 60% health, the fight changes shape. Bayle stops, stands still, and channels. Molten marks spread across the ground around him, then he and every mark detonate, and he comes out of it sprouting spectral wings. That channel is called Bayle's Tyranny, and it's your warning bell for phase 2. Run out of the marks and, if you have a bow or spells, punish him while he just stands there glowing. Free damage, no strings.

He'll usually follow the transition with an aerial attack: a half circuit of the crater spitting flame shots at you, ending in a dive-slide through your position. Don't watch the dragon, watch the projectiles. Sprint perpendicular to their lines, then roll into him as he slides past. Into, not away.

The meanest change is timing. His old moves come back wearing new delays:

Fatal Crush now erupts from the floor after impact. Glowing spots mark the blast zones, so keep your eyes down.
Lightning Spear sends a line of secondary strikes out from the slam. Roll them or, in some cases, just jump.
The aerial slam that needed one last-second roll in phase 1 now needs a second roll for the follow-up blast. Roll, take a step, roll again.
As a rule, count one full beat before punishing anything that touches the ground. Roll spam kills more runs here than Bayle does.

Then there are the genuinely new problems. Burning Skies has him fly a full pass across the arena breathing fire below, then loop around for a second, tighter beam pass whose path explodes after it goes by. Watch the ground, not him, on the first pass and roll through the wave. On the second, roll through the beam itself and then move perpendicular to its path before the delayed blast catches you.

The big one is Bayle's Flame-Lightning. He raises that right claw like Lightning Spear, but his wings come out, the charge runs longer, and the slam spreads cracks through the ground that detonate in a massive second explosion. Roll the slam, then jump or roll the secondary. Jumping clean over the shockwave works, and honestly it feels fantastic.

Keep your resists up the whole way. Flamedrake +3 and Boltdrake +3 together cover his mixed breath, Flame, Protect Me adds a layer, and that Ancient Dragon's Blessing from the priestess is worth 15% negation for 70 seconds if you saved it. If you're still hitting a wall, the Scadutree Blessing is the knob that actually moves the dial, so go fragment hunting before you go respec-ing.

Rewards and Dragon Communion

The kill pays out 490,000 runes (980,000 in NG+) plus the Heart of Bayle. The heart works like a remembrance with worse fine print. Trade it at the Grand Altar of Dragon Communion for one of two incantations, and that's the whole menu. You can't consume it for runes, you can't duplicate it at the Remembrance Duplication Coffin or a Walking Mausoleum, and only one drops per playthrough. Want both spells? That's an NG+ trip.

So, the choice:

Bayle's Flame Lightning channels the dread dragon's form over your right arm and smashes enemies with an exposed talon bone coursing with flame lightning. A big, slow, close-range smasher of an incantation.
Bayle's Tyranny is a roar with a heatwave burst that sets off violent fire eruptions around you. More of a mid-range area spell, and it counts as magma, which matters more than you'd think. The Talisman of the Dread, found on a corpse in Elder's Hovel back in Gravesite Plain, raises magma potency by 15%, and the wiki confirms that boost applies to Tyranny.

The altar's little shop has one more thing worth a look: Ghostflame Breath, a dragon incantation, for 3 Dragon Hearts. If you cleared the mountain properly you're sitting on a pile of those hearts already.

Next, loop back to the Grand Altar for the priestess. If you never gave her Thiollier's Concoction, she'll be gone when you arrive, and her last spot holds the Priestess Heart plus the Flowerstone Gavel weapon. The Priestess Heart is a reusable transformation toy that turns you into a humanoid dragon, which is mostly for fun. If you did give her the concoction, she instead rewards you with the Ancient Dragon Florissax spirit ash and the Dragonbolt of Florissax incantation. Neither set clearly beats the other. The Florissax route gets you a summon, the quiet route gets the transformation and the gavel, so it comes down to what your build wants.

Last stop is Igon. His greatbow, his four-piece set, and his bell bearing all wait on his body at the foot of the mountain, and that bearing unlocks Igon's Harpoon greatarrows at the Twin Maiden Husks. Gorge on the heart at the altar before you call it done, though. The priestess calls it the purest form of communion, and it's the only one of its kind you'll see this run.
