[PSO2 JP] Remnants of Other Worlds [Depth 150] 1-damage trick

Depth 150 has a very interesting gimmick. Masquerade's damage multiplier is increased like by an order of magnitude or so, turning most of his moves into insta-deaths, but it's a little-known thing that his base ATK stat is also lowered a lot at this stage.
Apparently, having DEF stats of at least 1900 would match his ATK stats, such that his damage output will drop to 1. This means his damage multiplier is totally negated, since 1 multiplied even by 100 is still 1!
