#1) The game's less than linear gameplay means you can spend as much time as you like leveling up your skills. Throwing rocks around to skill up your throwing is rather easy. Just hold down enter (with the rock Icon, or with "throw rock" typed up)
#2) The goblins never learn. You can spend days fighting them, earning cash and skilling up your fighting. (Easily earning more than enough to cover your potion costs, and still make a profit).
#3) The safest places to sleep to ensure survival are as follows: The Dryad's, Erana's Peace, 'Enry the 'Ermit's cave, the Hero's Tale Inn and the Stables. Anywhere else is certain death. (But don't worry, you'll sleep through the whole thing.)
#4) More to come later! Any suggestions can be mailed to josh @ legendsofglory . com (no spaces, of course!)
