Similar to an issue Faceless Void's Time Walk used to have (where Time Walk traveled only in 100 range distances, so if you targeted 440 range, you'd only go for 400, and if you targeted 460 range, you'd go for 500).

Skewer can only move Magnus in 31.666666666 range distance, so when targeting any distance which is not a multiplier of that, it rounds down, making the distance always being off by up to 31.6

This also results in its maximum range being (31.6666 * 28/31/34/37 = ) 886.666/981.666/1076.666/1171.666, instead of 900/1000/1100/1200, being short by 13.333/18.333/23.333/28.333 range.
