I agree with the third point, edited. The fourth point is just a personal preference, though I also agree. I never said "you need to do Hard Magnus only once per week", I just got lazy and said "whatever I said at Chaos Root Abyss, ditto with Magnus". I will be retouching both descriptions to make the reset part more clear I guess.

C Nebs I remember clearly can't yield decent effects at all and are a lost of nebs. B I need to recheck the list of effects and decide with that, I don't remember were I'd see for last time the list though. The list of effects that only A Tier can yield surpass whatever B can archive by a very massive margin, and the rank up B>A is not really that bad neither. Still, I need to recheck data, I might edit that part likely.

I messed up a bit the part with the Tyrants (after writing all that, the last part is a mess as a whole, I focused in the mid-game). 21% stat, then 7-8 stars, then 24%, then 10 stars, then 27%, then 11-12 stars, then 30-36% stat. Editing that now.
