I have Ryu-Oh and Sphinx. Yes, Sphinx is weaker than Mordred's debuff, but it is unknown by how much. Also, Mordred's version of Black Propaganda most likely has a higher base chance of success than Ryu-Oh's. Still, it's not like I'm running entirely without them...
But yeah, having Cthulhu would truly be a huge boon. Not only for the added damage from C Def (and extra reliability from having an extra Def debuff), but also from the extremely powerful Overdrive Reduction.I swear to god, every single time I run without combo- the very first thing that happens in wave1 is that all three mobs do double/triple attack on the same character and it's instant KO. Well, except against my Thunder team which has so much Defender stat they laugh it off, usually.
Anyway, I just hate running without it as long as I can help it. If I'm lacking B or either A, I'll bring that over it, but.There's no Pride stat, by the way. If you have slvl20 in a Pride weapon, it's just flat out 10% Assault plus the Pride base effect.
