Is there a way to tell how many temple crystals you have without consuming 6 of them?

It does preload the map and consume 6, but run won't start till you hit run temple (if you have 60 capacity that means you can store 11 runs). I'm not sure how or why it triggers it but occasionally it displays the total charges(46/60) instead of 6/6 in maps, I think it has to do with how far away to it you are when all monsters die

It shows for exactly 1 frame when you collect a crystal how many you have out of your max.

Not joking, there is a steelmage clip out there showing it.

It would say */30 above the open temple button. There's no way to keep track bc sometimes get 2 or 3 per map running t15 corrupted. Just gotta go check in temple.

Just one thing I'd like to add: you can teleport to the temple from any waypoint, you don't have to go through a beacon entrance in a map.
