[2020] Cure for Brain-shock

Open the character status menu and read the description of the debuff. If it can be cured, it will tell you how it can be cured there.

Originally posted by Teresa: Brain-shock is not a vanilla debuff, so it must be modded. If so, you should ask in the thread for that mod in the modding subforum.

Might be a translation thing- Brain-shock could be the translated form of Concussion.
