Here in this scenario you are nuked by truck kun transmigrating into gudako or gudao (per your choice), even if you never played fgo or even have not know about it, you'll automatically know everything about fgo storyline,facts and many more even having in an incredible photographic memory remembering even the smallest things a bonus if I had to say, fact is you've got a cheat to help specifically being three only able to choose two.
Unbroken sword: your mind is unbreakable, even if you are tortured in the most painful ways you would be unaffected (downside: this makes you forcefully Stoic, meaning you never show your pain or show any emotion as well it has a good effect or is it even a good effect let's say if a servant tries to use charm or fear it would be non affective).
Affinity: you have a higher affinity with every race that is said, not with any animals or anything like that or plants or objects only with races like humans,servants ,Fae or dead apostles and true ancestors,anything like that, the affinity is 70 percent of love or affection meaning the more you spend time with an individual the more the become in love let's say you've spend time with the Chaldea team going through the fuyuki or reaching the second singularity the Chaldea team would start to become obsessive and possessive this doesn't spare even our eggplant mash,(downside: being that sooner or later every individual whether dead apostle, human,Fae or even archetypes, enemies as well and even if a servant is killed they'll still remember everything would still have the effect on them).
Magus isolation: you'll gain magic circuits that have a greater quality than touko aozaki while also having the most magic circuits known to the modern day, (downside: being that you'll be seen as a selfish and evil person 50 percent and does not cancel out the affinity downside).
What combination would you make, how'll you clear the singularities and lostbelts?
