If you are able to have enough dps, which is currently easy to achieve due to the stacking enchanments bug, you can kill a super -dummy and gain and unreasonable amount of exp. This happend to me during one playthrough because I wanted to test dps with one of these wepons. One dummy got me to lvl 92 pre-hardmode. This will probably be fixed with the stacking enchanments.
