Literally 1st try (with BG, and 2nd try overall), so whole run is not that well thought out.
This was already done by a number of Servants, however
1) These Servants were usually lvl100 2k/2k NP5 10/10/10
2) This challenge is harder for Moon Cancers, 6th wave is just bullshit.
Also accidentally stopped recording at the end of 6th turn, so sorry for that.
