Yeah, I've seen Tsukuyomi's debuff a couple of times, and it's quite scary. They might not have elemental advantage, but they have -50% Def while I don't.

I don't know if I can solo Reiki or not. I don't really know do I even want to try. I really don't think I can hit ~12m like nonsensei did, I wouldn't wonder if it was closer to 20m due to lack of debuffs. Seems like a massive waste of time even if successful.
