“Summer 2013” experimental season. Online ranked games (reports, discussions).

I haven't looked at the save files, but I don't see any reason to be surprised. Judging by the report, there were about 10 angels there. Judging by the maximum console command used on level 122, it's clear that there were some hidden units/parameters/experience boosts.

We close in on the tactic using angels and knights, with an additional layer of cover on top. We cast a spell like mass shield. While the archers are dealing with the cover, they are shot down by the knights, and the angels take down the stack of archers in one hit. The battle is quite simple, with approximate losses of something like: all the cover units, a few knights, and maybe 1 angel.

And there were probably not 20 archers there, but a little less.

I see the difficulty not in breaking the Guardian of Order, but in the maximum console command on level 122; after that, it's just easy.
