Some of us already hired an aide, and I think all of us did so without looking into what that particular aide does.
I found out late (had him sailing a ship already) that my aide was actually an adventure aid, that also comes with adventure skills.
If you want those skills then it's all good, but it would have been better to check that out before I hired him.
If you want to hire aides with the right skills for you, check this
out before you hire one.
