Refusal of Thorns is a Genshin Impact Challenger: Series VII Achievement that you can get by using Pyro to burn all the thorns created by the Dendro Hypostasis during its Ring of Thorns attack. I thought that this was really easy to do as long as you bring the right characters and know what the Ring of Thorns looks like. Here's everything you need to know about how to get this Achievement.
How to burn all the thorns created by the Dendro Hypostasis during its Ring of Thorns attack in Genshin Impact
Start by paying a visit to the Dendro Hypostasis in its cave under Dar al-Shifa. For this particular Achievement, you need to bring a Pyro character. We also highly recommend bringing an Anemo character that can trigger Swirl to guarantee that the Pyro spreads quickly. Amber and Sucrose are sufficient free-to-play options.
Upon starting the battle, you need to wait for the Dendro Hypostasis to trigger the Ring of Thorns attack, which starts by summoning a tree, pictured above. This is usually the boss' fourth attack. If you defeat it too quickly, you won't be able to trigger it—so consider waiting instead if you have a strong team.

Once the tree has been summoned, attack it with Pyro to trigger the Dendro Hypostasis to summon thorns surrounding the area. This is the Ring of Thorns attack, and your goal is to burn all of the thorns with Pyro.
The best way to do so is to attack the tree with Pyro, then use Anemo to Swirl the Pyro. Doing so will cause the fire to spread from the tree to the thorns, burning them all away. As soon as all the thorns are burnt, you'll get the Challenger: Series VII Achievement called Refusal of Thorns.
