I’ve played iCBT1, played both CBT1 and 2 pretty hardcore.
1 week in iCBT1 got me to roughly 100.
Torch room was pretty much a 2 hour grind per level.
iCBT1 rates were exactly the same as kCBT1. (Literally the first test, every other test had higher rates)
iCBT2 took 1 week to get to 200.
Torch room grind was roughly 30 minutes per level.
Is it safe to say the rates are much higher then iCBT1? (Which we will assume its 1x because it was “vanilla” rates)
Is there a confirmation as to what EXACTLY the multiplier is? No, does anyone actually care what the exact number of the multiplied rate? No, but people do care that the exp is much higher then 1x. That i can confirm.
Just an FYI, some people dont talk out of their ass, some actually experienced a lower rate then what iCBT2 currently has and when they say its a higher rate, you sure as hell better accept it. You dont need to have IMC tell you rates were increased to know.
Oh and btw, kCBT 1-2-3 had actual exp number rolling up when you kill things. It was from the kCBT 3 reset patch that they decided to hide the numerical amount of exp.
(iCBT1 had the numerical amount of exp)
EDIT: You can still get the exp value per mob killed but that achievement book is buggy. It differs person to person.
EDIT2 : Oh yeah forgot to add more information. You might argue that i had a better group composition for torch room compared to iCBT1. Nope. My group comp in iCBT1 was 2 barb 2 linker and 1 archer rotating all 4 torch rooms. We had the whole 4 torch rooms for ourselves and still took roughly 2 hours per level.
iCBT2 i played with 1 krivis 1 hopelite 1 cyro 1 archer rotating in 2-3 rooms. Took us roughly 30 minutes per level. We even had to fight against 2-3 parties for the spawns during our grind sessions. Pretty damn sure rates are higher lol.
EDIT3: I also forgot to add in, in iCBT1 the blue rare mobs were much higher too! I’ve killed at least 20 blue rare mobs during my grind in tenet gardens. In iCBT2 i saw/killed my first blue mob in Demon prison, level 150ish
