Battle-Hardened Glacial Wolf: Glacial Soul
Insider's TLDR
Stygian.moe
• About 5s after starting the battle, the Wolf puts up a 24U Cryo shield that can be only damaged through Pyro Swirl and Electro Swirl. Fav and sac weapons are able to be triggered.
• After the shield is broken, the boss will entered a weakened state for 12s, lowering all resistances to -60% except for Anemo. Additionally, 60% of Anemo and Pyro DMG dealt during the shield phase will immediately be dealt to the boss after the shield is broken.
Trait du boss
Ancestral Wolf Spirit: Manifestation
At the start of the combat, the powerful opponent will summon an "Ancestral Wolf Spirit". While the spirit is on the field, the opponent is invulnerable to all DMG. The "Ancestral Wolf Spirit" is protected by a special Cryo Ward that can only be broken by Pyro or Electro Swirl Reactions. Once the Ward is shattered, the spirit will vanish, leaving the opponent temporarily paralyzed and dealing massive backlash DMG. The more DMG the opponent absorbs while the shield is active, the greater the backlash DMG will be; furthermore, Pyro and Anemo DMG will further increase this backlash DMG.

Hydro Tulpa: Turbulent Vortex
Insider's TLDR
Stygian.moe
• Every 30s, spawns 2 mini-tulpas with 12U Hydro shield. Use Cryo to insta kill it. If big tulpa absorbed a mini-tulpa, it heals 12.5% HP and goes into Rage mode, raising all RES to 200%. If ONE small tulpa is destroyed while big tulpa is in the absorption animation then it will stop the animation, correct timing is needed
• After a while, big tulpa will charge its ultimate and get a shield worth of 8.85% HP and ends CDs of all abilities while restoring full energy. If not destroyed, will one shot the on-fielder bypassing I-frames
Trait du boss
Twin Half-Tulpas
Affected by the Ley Line disturbance, 2 Half-Tulpas will emerge during the challenge at intervals. After some time, the Hydro Tulpa will absorb Half-Tulpas to enhance itself: It will heal a large amount of HP and grow larger, its ATK will increase, and it will launch more dangerous attacks. Use attacks or Elemental Reactions to destroy the Half-Tulpas in time or Freeze them to interrupt this absorption.
Torrential Flurry
Affected by the Ley Line disturbance, the Hydro Tulpa will deploy a Ward during the challenge and enter a charging state as it prepares to launch Torrential Flurry. If it is successfully unleashed, your current active character will be immediately defeated. When the Hydro Tulpa deploys its Ward, all party members' Elemental Skill and Burst CDs will be reset, while their Elemental Energy, Fighting Spirit, and Serpent's Subtlety will be restored. Breaking the Ward before the Hydro Tulpa can charge up will interrupt Torrential Flurry.

The Open-Eyed: Overbearing Contempt
Insider's TLDR
Stygian.moe
• The boss will have Recording Phases that last for 6s each. The first starts at 1:54 and the second at 1:43.
• During the recording phases, hit the boss with a PHEC element. The first record needs 5 hits (not application). In the second recording, using the same element takes 15 hits, while using a different element only takes 5 hits.
• After recording, the boss summons Elemental Stars. You have 17 seconds to break them. Each star is infused with its recorded element and is immune to that same element. Breaking a star launches at the boss, the first star deals 3% + 3% HP while the second deals 9% + 9% HP
• Recording two different elements makes the stars much easier to break while allowing their damage to trigger reactions like Melt or Vaporize.
Trait du boss
Oversight of Vigil
When combat begins, the Open-Eyed will enter the monitoring state: It tracks the number of times it takes Pyro/Hydro/Electro/Cryo damage. When the number of hits from any one element reaches 5, it will exit this state and record that element as a monitored target. If no element is successfully monitored, the record will remain empty, and it will instead deal a single instance of Geo DMG. After the first "Oversight of Vigil" ends, the enemy will re-enter this state again after a set interval. Due to the effects of the Ley Line Disturbances, the second monitoring phase lasts longer, and elements that have already been recorded will require a significantly higher number of hits to be monitored again.
Phenomena's Delirium
After completing two rounds of Elemental Monitoring, the Open-Eyed will take to the air and begin preparing "Phenomena's Delirium." It will release the previously recorded elements and summon two corresponding Active Elemental Stars. If no elements were recorded, it will instead summon Inert Elemental Stars with high resistance to all elements and Physical DMG. If the enemy summons two Active Elemental Stars of different elements, both stars will become easier to destroy. When an Active Elemental Star is destroyed, it deals a large amount of damage to the enemy based on the recorded element. If an Inert Elemental Star is destroyed, it instead deals Geo DMG to the enemy. Destroy all Elemental Stars to interrupt the preparation of "Phenomena's Delirium." If both stars are not destroyed within the time limit, they will explode, dealing massive AoE damage.
