PSA: You only have one shot for the ARC-XD step with the rocket relic on Totenreich

Something I assumed but opted to go in and unfortunately test myself when trying to run the EE on cursed. There's only one location that I'm aware of to pick up the ARC-XD and you are still able to use it despite the rocket relic but once you use it that's it. No second chances.

I even tested to see if it respawns at the same location in the square but went 4 rounds and it still hadn't respawned. So, if you want to use the rocket relic just be confident about the step 😄
