Yeah SEN doesn't qualify if they lose single elim to 100T and then LEV loses both their series, taking the 4th seed champs points slot. Unlikely, but possible.
Leviatán is guaranteed to qualify.
Points go LEV > SEN > 100T so the last spot will go accordingly.
G2 must win one series to qualify since they have a bye.
C9 and KRÜ must win two series to qualify, starting with themselves, so only one can make it through.
