Arknights Welfare CF-EX-7 Clear, Challenge Mode

A Flurry to the Flame level CF-EX-7, Birth of a Hero, Challenge Mode, cleared using only Welfare operators.

I am quite surprised that this run worked, since I made a mistake fairly early on. I was a bit late in starting Kroos the Keen Glint's skill on the second flock of Fowlbeasts and she got destroyed by the dead Oxmane. I decided to keep going and was able to pull it together. The key for this level was a heavy use of Wiredrones. Vigil was repositioned to attack enemies at the lower left (this was supposed to be Kroos' job at this point). Heavy Rain was moved to the lower left to block the enemies amassing there. And Tachanka was repositioned to attack along the bottom lane. When Kroos was ready to be re-deployed she was added to keep up the pressure on that lower left corner. Gladia was left to handle the right side, which she managed to do.
