Inventober #5 One eyed staff

 

    If this staff is taken and kept overnight, you will have a terrible dream of horrors, ending with you hanging from a tree. You wake up blind in one eye but gain a bonus on all spells cast through the staff and knowledge of an ancient language and one at random. You cannot part from the staff or else you lose your mind slowly (-1 wis per day separated, at zero go insane).
