From my testing, completing the
first Upper or Lower Mechagon of the week in Mythic+, will drop a Vision of Perfection related item equal to a Normal Mechagon Clear:
- Rank 1 Vision of Perfection
- 图纸:完美同步的差速齿轮 if you already have Rank 1
- One 序列链轮 for those players who currently have Rank 2, similar to completing a Mythic Operation: Mechagon run.
