Anthem™ | ToS Guide to 17k crystals in 15mins

This method is to be used on top of the usual method of obtaining multipliers in advance and killing the stage 1 MB at 8x ASAP.
If you have a squad where members communicate with each other, you can use this to efficiently earn 17k crystals in Temple of Scar.
I learned of this glitch first from ‪@KNOCKOUTxPSYCHO‬'s video:    • Anthem™ | Temple of Scar 20X method  
Subsequently, I learned that Playstation players knew of this earlier. ‪@Shuri_guratan‬ from Playstation shared this in    • Anthem™_ ToS glitch
