Slight Change For Various Mob And Boss Battle Rooms

As A guy who played multiple times as an archer, arrow shield "rain" can greatly help in many situations, however, this requires a space, space that sadly doesn't exist in such important places such as tower of ascension (even floor 7), Qira hive (all divisions lvls that aren't boss) and basicly any room you can recall that feels too small for being a good arena.

The suggestion should sound simple, because it is really is, just expand those rooms enough to let arrow shield "rain" to work correctly.
