- Disclaimer: Exorcism is only necessary under special circumstances, as most ghosts don't harm the host under possession.
- Mental composure majorly affects success of exorcism, with it becoming more difficult as the host's mental composure worsens.
- Forcefully rendering the host unconscious forces the ghost to leave. However, it is not recommended as it necessitates inflicting harm upon the host.
- Elements in opposing to the one the ghost is affiliated with can weaken their ties to the host, at the unfortunate expense of the risk of harming the host. Examples include darkness and light, and fire and ice.
- Religious faith mostly works similarly to mental composure in its success of influence. Only notable things to be found is that this applies to anyone of any religion, and it works separately from mental composure.
- Salt is the most influential tool in exorcism; applied on the body, it can dehydrate generated ectoplasm, severing the host's link to the ghost, at the unfortunate expense of hurting the latter.
- Success is also contingent on amount of ghosts within the host; other ghosts are unaffected by the exorcism of one and can repossess the host if desired.
- Good news: I think it's possible to exorcise myself after all.
- Bad news: Too many ghosts have possessed me by now.
