I thought about something you know in Naruto there is clan called kurama clan that have bloodline that make them very skilled in genjutsu and every hundred of years someone will be born with the ability to make the genjutsu real what if a player spend all his point to get this bloodline and then grind more points to get to one piece to get Observation Haki and Conqueror's Haki observation haki will be used to get info from his surrounding and conquer haki to strengthen his bloodline ability using conquer haki as domain and then go to hxh world to learn nen and make hatsu that will make his conquer haki domain smaller however in his domain he can have semi-reality warping ability and without using hatsu his domain is back to it size but he can only effect the anything that can get in the genjutsu without changing reality
