Having a Common Game Ability In Normal Life

As long as i can remember, i can see something other people can't see

Yes, on the top right of my vision, i have something that looks like a map, does it useful? how does something that blocks 1/32 of my vision to be useful? Does it have to be useful.. right?

As i get older, this looks like "mini-map" in a video game that i played, so i decided to call this Mini-map

at least I'm not the only one with this kind of thing.. from what I've found, everyone has different ability, for example my little sister can see another person status, there's a person that can heal wounds by eating meat, there's a person that once a day can spin roulette to get reward, there's a person that can jump twice in the air and there's a person that can throw fireballs..... wait a minute!?

the story will be slow, since i just write this to train my english

anyhow the idea of this story will be

if someone can throw a fireball does their hand burns?

if someone can jump for 30m can they survive the fall?

if a bard play a song that can regen their allies, why’s the enemy isn’t regenerating?

if a cleris creates a barrier can their allies attack from inside barrier?

and About the first few chapter

i know the grammar was really bad

but it’ll help me if you guys read the first few chapter and go straight to the last and tell me have i improve or not

P.S i hope The world has “common language” feature so everyone speak in the same tongue lol
