Shackle Me, That I Might Willingly Be Destroyed is a Genshin Impact Challenger: Series VIII Achievement that can be obtained by using Coppelius' attack to make all the Dirge's whirlwinds undergo Elemental Conversion. It must be done during the climax of the Dirge of Coppelia.
The prompt for this Achievement is tricky to decipher, so I'll show you exactly what you need to do to complete it.
How to make all the Dirge's whirlwinds undergo Elemental Conversion in Genshin Impact
This Achievement is tied to the "Icewind Suite" boss. Initiate the battle by speaking to Maillardet and choosing Dirge of Coppelia. I strongly recommend bringing a shielder or healer, as you'll get hit quite a lot while trying to fulfill Elemental Conversion.
Upon starting the battle, Coppelia and Coppelius will perform on the dance floor and barrage you with attacks. If you have a strong team, refrain from attacking the boss as you might defeat the pair before the climax. The climax of the dance occurs when the boss summons three Anemo pools, pictured above.
The goal is for Coppelius to attack each of the Anemo pools, which will only happen when you physically stand beside it and act as aggro. So you must stand beside an Anemo pool and wait for Coppelius to barrage you with Cryo attacks. Doing so will transform the Anemo pool into a Cryo pool, completing the Energy Conversion. Do the same for all three Anemo Pools until they all become Cryo.
Since you'll take damage over time while standing beside the Anemo pools, it helps to bring a healer or shielder to ensure survivability. Once all three have been converted to Cryo, you'll automatically unlock the Shackle Me, That I Might Willingly Be Destroyed Challenger: Series VIII Achievement.
