Genshin Impact - Electro Regisvine Boss Guide

gamespot.com:

The Genshin Impact version 3.0 update has added yet another plant boss to Teyvat: the Electro Regisvine. Sumeru's Regisvine is slightly tougher than the ones found in Mondstadt and Liyue, but you won't need to change up the strategy too much. Here are some tips for how to defeat this giant, electric plant.

This Regisvine is found within Sumeru's northeastern region, the Mawtiyima Forest. It's sitting inside a cave, just like its Pyro and Cryo counterparts. However, this cave entrance isn't located near the boss's map icon. Instead, the entrance is directly north of the icon. You'll know you're in the right spot when Electro Slimes and an Abyss Mage appear. Here's where to look:

Nothing the Electro Regisvine does should surprise players who have already fought the Pyro and Cryo versions, save for the core explosions. These bosses can't even move to avoid your attacks, so this fight should be a relatively simple one as long as you have good dodges, healing, or shields to keep the team alive.
