Genshin Impact: How to destroy the Electro Regisvine’s Waxing Stamen and Waning Stamen

Genshin Impact‘s Graven Innocence event not only gives players the chance to witness Sumeru‘s countless wonders; it also challenges them with its many dangers. Such is the case with the Behemoth Observation sub-event, where players must destroy the Waxing Stamen and Waning Stamen of the Electro Regisvine.

Unless you’re a newer player and trekked to Sumeru from Mondstadt to get Collei for free, you should have already fought a lot of Regisvines at this point. However, you must have wondered what stamens the game wants you to destroy and how.

These stamens are easy to spot and destroy. Here’s how you can do that.

Here’s how you can destroy the Electro Regisvine’s Waxing Stamen and Waning Stamen

To destroy these stamens, you will need to attack them with the Pyro or Cryo element. The Waxing Stamen is the one that appears as soon as the battle with the Electro Regisvine begins.

On the other hand, the Waning Stamen appears a little later in the battle.

Take note that when both stamens are present on the battlefield, they will unleash an Electrical Explosion. Therefore, you should destroy the stamens as soon as you can. Preventing this explosion is also one of the objectives of the Behemoth Observation challenge with the Electro Regisvine.

Like all Regisvines, the Electro Regisvine will also have its core at its corolla and roots, and destroying them will paralyze it. Therefore, after destroying the Waxing Stamen and Waning Stamen, destroying the cores should be your next goal. If you wish to quickly destroy the core at its corolla, you may consider bringing a Cryo or Pyro bow user such as Ganyu or Yoimiya.

Destroying the core at the bottom (the roots) is another thing you need to do to reap all the rewards of this challenge. If you’re bringing a melee Main DPS with you, destroying this core will be much easier than destroying the corolla one.
