Saint understood she lost all her skills and is trying to think of a plan, she knows her end if is discovered she got nothing.
Sadly as everyone but MC she is retarded and instead of taking her money from the bank account and running in a church to take repair or another country faraway where no one knows her she is staying with the group of people that have doesn't see people with bad skills as humans (she was one of them and had the highest morals somehow)
Mage is fully gone, she lost her intelligence
to who is wondering why they didn't realize what they lost, they got used to the power and a lot of passive skills, so many they forgot about it, the active skills were for dungeons instead so they didn't use them yet
their confidence is so massive they aren't even chekcing out the changes, after they got poisoned for losing 1 single skill
Tank guy most likely had some stamina and weight lended skills, without them he is suffering the weight of the armor
Seems like this world doesn't have level ups on people but only their skills
