The one gold is what our NPCs buy them for! I guess that's a perspective issue! Sorry about that.
I rewrote that part about "energy" to clarify it. I used the term that players had used to talk about it. The issue has to do with Stamina, and how often the character gets hungry or equipment shatters. Although items in other classes are on the list of things that deplete stamina, there aren't any archery items included.
The "stamina" or "energy" bar is purely decorative. It's dark when you're holding down tab but goes through a series of color changes as it "refills". The difference in the responses in a char with 1 Stamina and 20 HP or a char with 101 Stamina and 9999 HP is a matter of literally milliseconds. There isn't any difference based on equipped items, either - having "nothing" equipped (for punch, for instance) has the same effect as a Pharaoh Sword.
Thanks for noticing those things!
