If someone is skillless, they don't have any special abilities or talents.
Being skillless is not a good thing because it means you can't do things that other people can do.
Examples:
He is skillless at playing the piano.
She is skillless at fixing things.
The skillless man couldn't find a job.
I am so skillless that I can't even tie my shoes.
The skillless wizard couldn't cast any spells.
The skillless chef burned the toast.
