Let's say 3 SP regen every 3 seconds and you have 800+ SP. So in order for you to recover all 800 SP, you would need to be in game for 88 seconds. A match is 120 seconds, which leaves the first 32 of fighting which I highly doubt you'd get exo by that time. Boss mode, there's SP recovery and also when you die, you gain all your SP back cause we get verdas and ****. The only BM I would maybe think would fully utilize SP regen would be things like Vladimir's Castle. Is it even worth it? I was going for Sejul clothes for the SP regen + being able to use it for all classes + genders but I'm starting to think it's not needed.. I might just put gems on Aquarius Clothes since both the shirt and the pants are all genders + classes. They just don't have SP regen.
I mean all BMs give you ways to replenish SP plus ya boy stay strapped with the pots. I think 400sp + regen is enough unless you're entirely exocore dependent and spam them brainlessly but I think regen is worth it. I have an Avalon with the gems that give sp/hp forgot what they were called. It wasnt as nearly as fun as I'd thought it would be
