Mystery Cache Achievement on Normal (Fate's Unpredictable Favor) Imaginarium Theatre

Completing the Mystery Cache achievement on Normal difficulty in the Imaginarium Theatre in Genshin Impact. This took a few tries.

00:00 Rolling for Mystery Caches
03:50 Actual run begins
15:00 When the magic happens
17:40 Achievement Get

My basic strategy was just:
Get extra refresh dice for the end
Get characters as fast as possible so they're removed from the pool
Get as many Flowers as possible for more rolls (this I got very lucky in)
