Records of the Fall is a Genshin Impact Wonders of the World Achievement. You can unlock it by applying Pyro onto the Dendro Hypostasis' Vine Shell while it's performing a Plunging Attack. To get this Hidden Achievement, you must first have access to the Dendro Hypostasis, located in a cave south of Dar al-Shifa.
How to get the Records of the Fall Achievement in Genshin Impact
The Dendro Hypostasis will turn into a ball called a Vine Shell and perform a series of Plunging Attacks after the first exposure of its core. Your goal is to wait for the precise moment it lands and then attack it using any Pyro skill.
The Dendro Hypostasis will make a huge jump to prepare for a Plunging Attack. A green circle will appear on the ground for a second or two, indicating where the boss will fall. Stay close to the green circle (but not on top) and wait for the Dendro Hypostasis to fall to the ground. Once that happens, immediately apply Pyro to unlock the Wonders of the World Achievement called Records of the Fall. Since the Dendro Hypostasis makes multiple Plunging Attacks, you have plenty of opportunities to try to get this Hidden Achievement in each battle.
