Extra Weapon
The Punch is a powerful undocumented weapon, especially useful against creatures that destroy weapons. On the Options screen, choose the WEAPON icon and discard your equipped weapon.

Maximum Armor
Pick up two short bows then equip them one after the other to get a 99 AC without ever wearing armor.

Quick Kills
If you want to kill a creature in about 1 hit you must do a VERY sharp turn right into the creature. The key to this trick is all in the timing!
