I need answers

Are 100T on The Lev side of the bracket or the G2/SEN side of the bracket? If sen win tmr, does that also guarantee lev spot at champs?

Depends if 100T win or not. Knockout games are group 4th v 5th and 3rd v 6th (according to liquipedia).

If sen win tmr, does that also guarantee lev spot at champs?

this i have no clue
