How to let the Electro Regisvine perform its charged electrical collision in Genshin Impact

Just like other Regisvines, the Electro Regisvine's core will move between its corolla and roots. Whenever the boss switches between the two, it will summon a triangular node, which can be removed by attacking it. If you're attempting to get this Achievement, you must not attack any of the nodes.

The first triangular node (pink) will appear shortly after the battle starts. Do not destroy it. Instead, wait until the Electro Regisvine's core forms at its roots, which will cause another triangular node (purple) to appear. Likewise, do not destroy it.

Once there are two nodes, wait for them to collide and knock you back with a massive explosion. Get hit by the attack to immediately obtain the Hidden Achievement called When Autumn and Dew Meet. If you accidentally destroy the nodes, you can try again by engaging in battle with the boss again.
