You can fight forums that are any number of levels higher. I am 99% sure that you bottom out your attack at 10%. If you are willing to spend the time and consumables, you can go after whatever you want. (I don’t advise the high end hard hitters though, since you will not be able to heal fast enough to kill them.)

Btw, Episode 2 is worth it, grab it when you can. Maybe enter some of the contests that are giving away BPs.
