The Pyro Regisvine is a Normal Boss in the Liyue region, located in a circular arena-like structure between Luhua Pool and Tianqiu Valley. It takes on the appearance of a large version of the Pyro Whopperflower. There is a glowing core at the center of its base, and the boss cannot take damage when its shell is intact.

When defeated, the player must consume 40 Original Resin to claim its drops, which consists of Artifacts and Character Ascension Material for Characters using the Pyro element.

Description

A giant vine that has absorbed the ancient flame that rages within the Ley Lines.
It is restless, as if filled with an endless fury.
Poets, bards and even some academics believe that elements also contain emotions and hope. If this is true, then one can only wonder what emotions cause the Pyro Regisvine to burn eternally, writhing like one longing to be free of the confines of the earth...

Abilities and Attacks

See the Attack Gallery for pictures on the Regisvine's moves.

Opening Phase

Upon either attacking it from range or after entering its arena, the Pyro Regisvine will unfurl from its resting position and stand outright. A short animation will take place, and the Regisvine's shell cannot be damaged until the animation begins. Take advantage of this, as it will not resist your attacks during this animation.

The Regisvine, if not knocked out during this phase, will continue to use the following attacks until you do so:

  • Faceplant: The Regisvine will slam its face into the ground after locking into your current position, sending Pyro tremors through the ground in the direction it faceplants.
    • The Pyro Regisvine locks on to your current position once it starts shaking its head. Do not dodge before this animation, as it has not locked onto you yet. Maintaining a medium distance just a few metres/steps away from the Regisvine allows for quicker dodging.
  • Rapid Fire: Using its buds (arms, in a sense), the Regisvine will fire small fireballs at the player in rapid succession.
    • You do not need to sprint when dodging this attack; dashing once or twice when you're about to be hit will do. Unlike the faceplant, this move is better dodged on the edges of the arena, although the medium distance used for dodging the faceplant is sufficient, as long as you remember to dash when the fireballs start to catch up. A quicker method is to stand still for a moment, and dash towards the shots when they are close to you. Don't do this too late, as they will not be high enough above the ground to dash under.
  • Flail: The Pyro Regisvine will slam its head on the ground and sweep it 180 degrees, knocking back any characters.
    • Dashing around the Pyro Regisvine's base (only achievable if you are very close to the base) will allow you to escape the radius of the attack. Dashing backwards is less viable, as you may be too close to the base to escape, but it allows you to deal damage to it (and to its shield/gem). In addition, use of polearm users' Charged Attack (Xiangling's, Zhongli's, Xiao's Elemental Skill) allows you to dash through the base, escaping the radius easily.
  • Fireball: After a short charging period, in which the Regisvine gathers Pyro in its buds/arms the Regisvine hurls a massive fireball at the player.
    • This attack can be easily dodged by running to the Regisvine's base. If doing this beware of subsequent attacks that you may be vulnerable to. Dashing sideways is a valid option as well, but make sure you maintain at least a medium distance or closer (5–6 metres).

Waking/Transitioning Phase

During this phase, the Pyro Regisvine will regain consciousness from being knocked out, which can be achieved by destroying its Pyro elemental shield. After fully awakening, it will immediately perform a triple flail.

  • Triple Flail: The Pyro Regisvine will slam its head on the ground and sweep it 180 degrees, knocking back any characters. It will do this one more time, then, after a very short delay, it will sweep its head in a 300 degree radius.
    • Dashing around the Pyro Regisvine's base (only achievable if you are very close to the base) or using a polearm user's Charged Attack (or Xiao's Elemental Skill) will allow you do escape the radius of the attack. This will work for the first two flails, but not the third. Dashing backwards and using a ranged character to deal damage is ideal, and it allows you to deal damage to it (and to its shield/gem).

Inner Ring Phase

This phase occurs after the Pyro Regisvine's awakening phase, and it will only happen if the Pyro Regisvine was knocked out by destroying the Pyro shield on its base. When this phase begins, the Regisvine will immediately perform the Eruption move. Sometimes, it will perform a single Flail before doing this. The Eruption move can only be performed once during this phase.

During this phase the Regisvine will use the following attacks:

  • Eruption: The Pyro Regisvine will point its corolla upwards, along with its buds, as if it were in the idle animation, and cause Pyro energy to erupt from the ground. More Eruptions occur near to a player, and eruptions are almost entirely absent near the base.
    • As eruptions are rare near the base, you can run (not sprint) in circles around the base. Do not perform any moves that have extended animations, as you could still be caught by an Eruption.
  • Triple Faceplant: The Pyro Regisvine will shake its head, locking onto your current position and slamming its face into the ground, sending Pyro tremors through the ground in the direction of the faceplant. It will repeat this 2 more times (3 in total), each in rapid succession (the targeting period in which it shakes its head will become noticeably shorter in the last 2 faceplants). After the third faceplant, it will rest its head on the ground, allowing you to deal damage to its head.
    • Take advantage of the third faceplant to deal Hydro damage to its head if needed. As with the normal faceplant, maintaining a medium distance is ideal. Because the last 2 faceplants have much shorter targeting periods, staying closer will greatly help in dodging them. Remember, don't dodge until it shakes its head.
  • Double Flail: The Pyro Regisvine will slam its head on the ground and sweep it 180 degrees, knocking back any characters. It will do this one more time, in a 180 degree radius, and occasionally, a 300 degree radius.
    • Dashing around the Pyro Regisvine's base (only achievable if you are very close to the base) will allow you to escape the radius of the attack. Dashing backwards is less viable, as you may be too close to the base to escape, but it allows you to deal damage to it (and to its shield/gem). In addition, use of polearm users' Charged Attack (Xiangling's, Zhongli's, Xiao's Elemental Skill) allows you to dash through the base, escaping the radius easily.
  • Pyro Spin: A circle of Pyro will appear around the Regisvine, indicating the radius of the attack. It will then flatten and stretch out its petals and spin, dealing large amounts of damage within the previously marked radius, knocking any characters back and infusing the ground in the radius with Pyro. The infused ground will deal continuous Pyro damage until it dissipates.
    • This attack cannot be dodged, save for the use of Elemental Burst invincibility frames, but can be easily avoided by dashing outside of the radius. The Pyro infused ground is not removable (it will only dissipate by itself), so be wary of your characters' health.
  • Faceplant: The Regisvine will slam its face into the ground after locking into your current position, sending Pyro tremors through the ground in the direction it faceplants.
    • The Pyro Regisvine locks on to your current position once it starts shaking its head. Do not dodge before this animation, as it has not locked onto you yet. Maintaining a medium distance just a few metres/steps away from the Regisvine allows for quicker dodging.
  • Rapid Fire: Using its buds (arms, in a sense), the Regisvine will fire small fireballs at the player in rapid succession.

  • Flail: The Pyro Regisvine will slam its head on the ground and sweep it 180 degrees, knocking back any characters.
    • Dashing around the Pyro Regisvine's base (only achievable if you are very close to the base) will allow you to escape the radius of the attack. Dashing backwards is less viable, as you may be too close to the base to escape, but it allows you to deal damage to it (and to its shield/gem).

Outer Ring Phase

This phase occurs after the Pyro Regisvine's awakening phase, and it will only happen if the Pyro Regisvine was knocked out by destroying the Pyro gem on its corolla/head. When this phase begins, the Regisvine will immediately perform the Triple Faceplant move. As with the Inner Ring Phase, the Eruption move can only be performed once during this phase.

During this phase the Regisvine will use the following attacks:

  • Triple Faceplant: The Pyro Regisvine will shake its head, locking onto your current position and slamming its face into the ground, sending Pyro tremors through the ground in the direction of the faceplant. It will repeat this 2 more times (3 in total), each in rapid succession (the targeting period in which it shakes its head will become noticeably shorter in the last 2 faceplants). After the third faceplant, it will rest its head on the ground, allowing you to deal damage to its head.
    • Take advantage of the third faceplant to deal Hydro damage to its head if needed. As with the normal faceplant, maintaining a medium distance is ideal. Because the last 2 faceplants have much shorter targeting periods, staying closer will greatly help in dodging them. Remember, don't dodge until it shakes its head.
  • Double Flail: The Pyro Regisvine will slam its head on the ground and sweep it 180 degrees, knocking back any characters. It will do this one more time, in a 180 degree radius, and occasionally, a 300 degree radius.

  • Fireball: After a short charging period, in which the Regisvine gathers Pyro in its buds/arms the Regisvine hurls a massive fireball at the player, after which a flaming flower will spawn at the target location.
    • This attack can be easily dodged by running to the Regisvine's base. If doing this beware of subsequent attacks that you may be vulnerable to. Dashing sideways is a valid option as well, but make sure you maintain at least a medium distance or closer (5–6 metres).
    • Destroy the flaming flower to avoid it erupting and creating a patch of Pyro energy.

Strategies/Tips

When fighting the boss, prioritize reactions like Cryo reaction Melt or the Hydro reaction Vaporize, as it is weak to this type of damage. Do not, however, rely on Pyro damage, or use Pyro characters, for their usefulness is limited here.

Using a Hydro character like Barbara or Xingqiu to quickly break its shell, as this stuns/knocks it out in the process.

  • The shell takes a while to reform. To knock out the Regisvine before the shell reforms, target its head/corolla with Hydro. This can be done using Childe's aimed-shot. If you don't have him, wait until the Regisvine performs the triple faceplant, as on the third faceplant, there is a long pause where its head remains on the ground. Another opportunity for this is just after the Regisvine awakens, as it will always perform a sweeping attack, so step back and use a ranged Hydro user like Barbara to whittle down its head while it performs the attack.
