ok so here's a small guide for how to get all four bars full on hero
1. attack - 2 halberds
2. defense - 2 chest armor
3. magic - 2 big potions (careful here not the medium ones)
4. range - ok this one is a little tricky you can do it in the smallest space with sling shots but that takes 4 and 40 ammo hard to come by in a single run. you could use muskets and it would only take 3 with full ammo that's 18 bullets, not as hard to get in a single run but costly in terms of space. the best way I've found is to use one of each fully loaded.
good luck and good hunting
