How to Conquer Siora, Blade of the Mists in Path of Exile 2

Path of Exile 2 (PoE 2) is renowned for its challenging boss encounters that test players' reflexes, build optimization, and strategic thinking. Among the game's pivotal interlude bosses, Siora, Blade of the Mists, stands out as a corrupted fey warrior whose lightning-infused attacks and mist-shrouded arena demand precision and adaptability.

Unlike optional bosses that offer side rewards, Siora is a mandatory encounter for progressing through the "Recruit the Ezomytes" interlude quest. Defeating her not only advances the campaign but also frees her from the Blackwood's curse, earning you the fey's aid in navigating the region's darkness. This guide breaks down everything you need to locate, prepare for, and conquer Siora, Blade of the Mists. At the same time, you will also receive more rewards such as POE 2 Currency.

1. Locating Siora: The Stones of Serle

Siora resides in the Stones of Serle, a location you'll reach after defeating Isolde of the White Shroud and Heldra of the Black Pyre in the Scorched Farmlands. This ancient, rune-adorned area is home to several runed megaliths-your key to spawning the boss.

To trigger the encounter, you must first activate all the runed megaliths scattered throughout the Stones of Serle. Once all megaliths are active, head to the center of the area and step into the glowing runed circle. This action will summon Siora, who emerges from the mists to defend the stones she has been draining of energy.

Note that the Stones of Serle is also populated by regular enemies like Werewolf Prowlers, Skeleton Spriggans, and Lightning Wraiths. Clear these foes first to avoid distractions during the boss fight-being ambushed mid-battle can quickly turn the tide against you.

2. Siora's Basic Info: Strengths, Weaknesses, and Damage Types

Understanding Siora's core traits is critical to building a counter strategy. As a fey corrupted by the Blackwood's curse, she wields dual lightning-infused sickles, blending fast melee strikes with ranged elemental damage.

Siora's damage profile focuses on physical and lightning damage, and she can apply debuffs like "The Blade's Storm" and shock, which slow your movement and increase damage taken over time. Early PoE 2 versions listed no clear resistances or immunities for Siora, though later updates confirmed she has moderate evasion, making hit chance a consideration for melee builds.

Her primary weakness is fire damage-focusing on fire-based skills or gear will significantly boost your damage output and shorten the fight. Unlike some bosses, Siora has no phase-specific health regen, but her fast attack speed and area hazards can make sustain a challenge.

3. Siora's Key Attacks and How to Dodge Them

Siora's attacks are relentless but predictable, with clear visual cues to help you dodge. Mastering these patterns is the difference between surviving and being overwhelmed, especially in the arena's cramped space.

Sickle Swipe and Spinning Combos

Siora's most common attack is a rapid sickle swipe, delivered in a straight line in front of her. When you're in close range, she will chain these swipes into a spinning combo, hitting all targets within a small radius.

The dodge here is simple: sidestep to her left or right, as the swipes only cover the area directly in front of her. For the spinning combo, back away slightly-she cannot extend the combo's range, so a quick retreat will keep you safe. After the combo ends, she has a 1-2 second cooldown, which is your window to land a few hits.

Lightning Line and Lightning Bolts

When you're at a distance, Siora will cast a straight line of lightning, which travels across the arena and deals heavy damage on impact. This attack has a bright blue visual cue-watch for the ground lighting up, then move perpendicular to the line to dodge.

As the fight progresses and her health drops, she will summon random lightning bolts that fall from the sky. These bolts leave small AoE zones of damage, marked by yellow warning circles on the ground. Keep moving to avoid standing in these zones, as they stack shock damage if you linger.

Mist Shroud and Darkness Phase

Siora's most dangerous ability is her Mist Shroud, which she activates periodically (usually when her health drops below 90%). She shrouds herself in a damaging black mist that fills the entire arena, reducing visibility and inflicting minor chaos damage over time.

To survive this phase, immediately locate the shining runed megalith in the arena's center. Stay within its circle of light-the megalith's aura dispels the mist and blocks the chaos damage. If you step outside the light or fail to reach it in time, the mist will quickly drain your health, especially if you're already weakened by shock debuffs.

Arena Boundary Hazard

One easy-to-miss danger is the arena itself. The Stones of Serle's boss arena is cramped, and stepping outside its boundaries inflicts continuous chaos damage over time. Never backpedal blindly-always keep an eye on your position relative to the arena's edges to avoid this unnecessary damage.

4. Best Strategies for Beating Siora

Siora's fight is a balance of dodging hazards and capitalizing on her vulnerabilities. The best strategies focus on movement, target positioning, and build synergy-here's how to optimize your approach.

Positioning: Stay Behind, Stay Mobile

Siora's attacks all face forward, so positioning yourself behind her is the safest way to deal damage. Use quick movement skills (like Dash or Leap Slam) to circle around her after dodging a swipe or lightning line.

Avoid staying in one spot for too long-her lightning bolts and mist phase reward constant movement. Even when attacking from behind, take 1-2 hits then reposition to avoid being caught off guard by a spinning combo or sudden mist activation.

Build Recommendations

While any well-optimized build can defeat Siora, some archetypes fare better than others:

Fire-based builds: These are ideal, thanks to Siora's weakness to fire. Fireball, Flameblast, or Fire Strike (for melee) will melt her health bar faster than other elements.

Ranged builds: Bow or spellcasters have a natural advantage, as they can attack from a distance, avoiding her melee swipes and easily dodging lightning lines. Use hit-and-run tactics to stay out of her reach while dealing consistent damage.

Melee builds: If you prefer melee, prioritize high evasion or armor to tank her swipes, and use a fast weapon to capitalize on her cooldowns. Avoid slow, heavy-hitting weapons-you need to attack quickly and reposition.

Consumables and Preparation

Before the fight, stock up on essential consumables: Healing Flasks to counter her damage, Mana Flasks (for spellcasters), and Shock Removal Flasks to clear her debuffs. If you have access to Fire Damage Potions, use them to amplify your damage against her.

Upgrade your gear with resistance mods-lightning resistance will reduce the damage from her lightning attacks, while chaos resistance helps with the mist and arena boundary damage. Even a few points of extra resistance can make a huge difference in sustain.

5. Rewards for Defeating Siora

Defeating Siora is primarily a quest progression boss, but she offers valuable rewards for your effort. The main reward is advancing the "Recruit the Ezomytes" interlude quest, which unlocks new areas and NPCs in the campaign.

While she doesn't drop unique items consistently, she often rewards rare gear, crafting currency (like cheap POE 2 Orbs of Alteration or Transmutation), and experience points-critical for leveling up your character before later, harder bosses.

After defeating her, Una (an NPC in the Stones of Serle) will appear to speak with you, guiding you to the next step of the quest: returning to the Scorched Farmlands to face the darkness there.

Final Tips for Success

Siora is a test of patience and reflexes, not brute force. Here are a few final tips to ensure your victory:

Watch for visual cues: Every attack has a tell-blue light for lightning lines, yellow circles for lightning bolts, and black mist for her shroud. Learn these cues to dodge instinctively.

Don't overcommit: It's better to land 1-2 hits and dodge than to stay in range for a full combo and take heavy damage. Siora's cooldowns are short, so you'll always get another chance to attack.

Clear adds first: Even if you think you can handle Siora while fighting adds, the extra damage and distractions will make the fight far harder. Take 2-3 minutes to clear the Stones of Serle before summoning her.

With the right preparation, positioning, and knowledge of her attacks, Siora, Blade of the Mists, becomes a manageable encounter. Use this guide to refine your strategy, leverage her weaknesses, and claim victory-one lightning-dodging step at a time. Good luck, Exile.
