May some generous soul make Table List of rank 1 and rank 2 …rank3? status effects and a detailed mechanic explanation on how the status effects work. aswell as counters(consumables and skills) to the status effect.
or one of the fansites. or even better an official IMC list of buffs and debuffs.
example(not from tree of savior):
advance thank you! <3
iirc they are listed with a level in the data of the game, so in teory you could just datamine them.
But for now the closest thing I’ve gotten was when talking around with a guy from my guild, we reached the conclusion that statuses that appear in classes between rank 1 to 3 are ‘‘Lv1’’ statuses and between Rank4 and 6 are ‘‘Lv2’’ with Rank7 having ‘‘Lv3’’ statuses. This was reached taking in count when kills that heal certain levels begin to appear, with Plague Doctor being able to become immune to Lv1 and 2 and 80% on Lv3 with the reasoning that it’s on the class level as the class is centered around status efects and it’s the only class that mentions this level this far.
AFAIK, all status ailments that are accessible from c1 classes are rank 1 status ailments.
All status ailments that are accessible from c2 classes are rank 2 status ailments, and so on. But this isn’t confirmed yet.
Level 1 examples that I know :
Sleep, from wizard c1
Freeze, from cryo c1
Bind, from linker c1, squire c1, corsair c1
Telekinesis, from psyco c1
Petrify, from elementalist c1
Stop, from chronomancer c1
Stun, from quarell shooter c1, barbarian c1, rodelero c1
Poison, from wugushi c1
but @Jariu theory makes sense.
So TLDR
C1 = R1 status
C2 = R2
C3 = R3
k, though some fansite would still me want to include a table for status/buff effects.
Have you tried Google before you post?
You can simply add the Rank from it. If you are too lazy to even do that, then I am not sure you deserve it.

Note: Rank 7 and not all Rank 6 are included, I believe.
Kind gentlemen, Mr. Indeed, thank you for your education on my incompetence.
May I ask? do you have the spare time to turn the information into a spreadsheet table as the thread suggested? for I am unable to do as I am preoccupied with 
celebrations. I would truly be thankful.
I shall gift you with prayers and blessings on that behalf.
Nope, I still need to work tomorrow. And I don’t deserve it neither. Thanks for the salvation.
