O yes, I drink 4L of water in a daily basis because I like it, not because my body is addicted to water since I was born. After all, I can quit my addictive vices anytime I want, I just don't want to stop drinking water for now.
Also, since the poison resistance didn't activate (you know it because paramal is affecting him) paramal really isn't a drug, but it also didn't activated his mental corruption resistance, so it doesn't affects his mind in a negative way.
so it's somehow not a poison nor mental magic, and supposedly??? not addictive, but it's... probably addictive, ya know... hopefully it's cleared up by the status reset and healing magic of the waiting room.
