Got another question

Hire a helper.
Should I work on leveling one up or wait?
And is there a quick way to level I try ed to start on a lower level and have my main as a flower and I started floor 1 on m3 and was getting like .1 exp.

Well what I did to get my non farming warr up to lvl 50 was used him as a hireling. An did floor 200 a few times. An if u want more exp. Restart the map till you get the experience shrine.
