The final act of The Chalk Prince and the Dragon event begins in Genshin Impact. It will see you confront the Resurgent Cryo Regisvine, a plant that we've already encountered. However, this version is a tough cookie, one you'll need to overcome if you want that all-important Miraculous Essence. Here's how to take it down.
Resurgent Cryo Regisvine Fight Details
Before going straight to kill the plant boss, you must complete the Uninvited Guests story quest, the fourth in The Chalk Prince and the Dragon series. Without it, you won't be able to start the final act.
The questline shouldn't really give you too many headaches, allowing you to progress to the Frostborn Miracle challenge.
Head to the location marked above to start the fight, which can be done either in solo or co-op modes.
How to beat the Resurgent Cryo Regisvine
The Resurgent Cryo Regisvine is a relatively tough opponent, but not too difficult. The difference here is that it has Frost Thorns that give it a shield. Killing the mobs that spawn will grant you Scarlet Quartz, that you can then use to destroy three of the Frost Thorns.
Then, the Regisvine will summon a deadly blizzard, in which you'll need to monitor your cold levels. Even so, once taken down the weak spot will be exposed, during which you should hit it with everything you have — even expending Scarlet Quartz to end this stage as soon as possible.
Here you'll need to be aware of the Seeds of Winter that will spawn near Ruin Braziers. A massive snowstorm will be incoming, one that could end a character in just three or four ticks. These Seeds will offer protection from the storm in the form of another shield, but not the follow-up strikes that will come.
In the final phase, there'll be several blasts of ice and another blizzard, before the entire cycle starts over once more. Just repeat the above until the boss is defeated.
