I'm not saying definitively that Giorno needs the arrow for Requiem, I'm just saying that it's the theory with the least assumptions, and therefore what we should probably use for further theorizing.

The arrow straight up fuses with Gold Experience to create GER. The arrow then falls off of GER later, and we don't see Giorno use GER again. In the manga, it's clear that Giorno doesn't just have the arrow, but that it falls off when he retracts GER. Why else would Giorno keep the arrow around, if he didn't need it?
