Custom Hero Chaos

What happens when a Pro Gamer who he thought was dying, wakes up with the message: [Choose your hero: Shadow Fiend, Medusa, Storm Spirit] [Choose your talents: Magus, Blitz Strike, Grand Librarian] Note: English is not my native language, I apologize for any inconveniences. I am also not a pro novel writer but a 3.2k hours dota 2 gamer who likes fun stuff. I do expect non dota players to read this so It will be non dota friendly. This work is heavily inspired by Dota 2, Custom Hero Clash [Dota 2 Custom Game], Eleceed, I Alone Level Up.
