No one fighting within 400 feet of yourself - Total control of the Quantum Field within 2 light-years of yourself.

Excuse me?

Everyone got a Skill Tree when they turned 15. Caveats certainly weren't uncommon, but such a strong caveat on every single skill, leading up to that, well...

No one fighting within 400 feet of yourself - ability to spontaneously create any material anywhere in the universe.

No one fighting within 400 feet of yourself - No one CAN fight within 400 feet of yourself, but yourself.

No one fighting within 400 feet of yourself - Go back in the Skill Tree and multiskill.

The powers kept getting more and more OP. But reading the last one, then reading the many other alternatives, I knew what to do.

I would become the most skilled being in the galaxy. Time to multiskill. After I got multiskill, though, I wanted to go for the inability to fight one. Best to keep my mutliskill skill.
