So this Tower Challenge event is pretty awesome. From when I started playing, there's this element I really like where they mythologize popular characters and just have extreme interpretations of their ideologies interact and clash with one another. This event is basically that distilled, without being bogged down with all the plot (because honestly I haven't cared about the whole end of the world thing or Chaldea or, maybe specifically, all those inconsequential interruptions from Mash and Romani).
Unlike most other events where the Servant just goof around and do dumb things, I feel all the major characters here become cool. They even made Gilles seem kinda cool! More events like this, please.
