I hate the 27f plus disk crabs. There are only a few characters that are in my party that can OHKO them reliably(Certain NEET, 26F, Nitori lolol, MarisaSpark, maybe 24F on a good day), and only a select few can even damage them (Patchy [Silent Selene and possibly Undine], Rumia, probably Yuugi and Suika if buffed) How much magic will Rumia need to OHKO them with DSotM? 24F is inefficient, NEET runs out of SP Hourai Barraging other stuffs very quickly, and the other options are single-target and expensive.
