It's been a whole entire year since I updated. May God and the Universe forgive my sins for conducting Intranquil Spirit experiments on "innocent" people for the past year. They may be deserving being bad or abusive people in relationships, but still... one's magical abilities should not be misused.
Then there are the other observations universal in magic. Magic/IS cannot take a person's free will away/make them do things of which they don't really want to do etc. However I can say though, one thing is very certain about the IS on the victim. If evoked correctly it will surely cause suffering in the victim, whether or not the victim gives in to what he or she is forced to do. Suffering is guaranteed. The victims almost always make some form of contact, whether to beg or insult the caster.
On a personal note I have had enough of the Intranquil Spirit, at least for now. It is most certainly not a good idea to be used for reconciliation I will even go so far as to say in most cases it is useless for reconciliation (unless the victim was dumped not the other way around, as stated in my other post about IS), but very good as a revenge love spell in which the caster does not want the ex-lover back. The ex-lover will really, REALLY get it from this spirit.
