Stress from Forking
Credit to Codebreaker on the official forums
Stress from Forking – Every time someone creates and runs either an Alpha or Beta fork of their ego they risk suffering stress damage. Every time they create a fork they must roll either WILL*3 (For creating a Beta fork) or WILL*2 (For creating an Alpha fork). If they succeed they do not suffer any ill effects. If they fail the suffer from either 2SV (For creating a Beta fork) or 1d10/2SV (For creating an Alpha fork). We didn’t think that the possibility of someone being able to constantly fork themselves with no consequences (other than the social) was thematically fitting for our table, so we changed it. We explained it away by suggesting that the process of creating and running a fork would be mentally stressful to both the fork and the original ego. The stress damages inflicted are low enough that for someone who just creates a Beta fork every few days they do not really have to worry, but high enough that if someone wants to create an army by farming their own mind they are going to run into troubles.
