so , you better do inside dungeon to find Leaf cats (HIT WITH FIRE ARROW. ) leaf cats have more job experince compared to other monster same level . Base level not so much, if you want faster to up you job level you can kill leaf cat.
That or get better arrows and head to toy factory lvl 2
I've done both. I find that hunting Leaf Cats made me level up faster than the TF; just (as someone else mentioned) stay away from the "monkeys" (wootang fighters). At level 55 or so, I was able to handle them, but only by spamming meat while I double-strafed.
If you go to TF, use at least iron (or better, steel) arrows. Hit-and-run with Chepet, and try not to let more than one Cruiser target you at a time. Stay away from the Stormy Knight (well, duh).
