Simple Q&A (By RAW) III

[Asmodeus]

How do you get 15' reach with a standard human Monk? It's just a reach weapon, so it doubles your natural reach (5' for a medium-sized human Monk). My question was how I can increase that natural reach and still remain a medium-sized human Monk.

My mistake. I was thinking of the Whip, which has a 15' reach.

The only thing I've got left to suggest is to have a wizard research and create a new spell.
