What’s more useful? is it megaphones, soul crystal, warp scroll, or repair kits?
I’d stockpile soul crystals until you always have atless 5 on yourself then you can buy phones whit the rest.
I’d prioritize Soul Crystals first. Followed by Warp Scrolls.
soul crystals and warps scroll in my opnion are the best…
i go 1 soul crystal and 1 megaphone everytime i reach 5 TP
it restores 1 TP every 4 hours. so just spam one whatever you need.
