Stealth
Stealth allows a character to move silently while maintaining invisibility, but it becomes much easier to detect such a character compared to Hiding. This skill also counts towards your ability to perform Special Moves. A character must have at least 50,1 in Hiding to be able to use Stealth. Otherwise, the message "You are not hidden well enough. Become better at hiding." will display. Stealthing is more difficult when wearing heavier armor, which is also a factor in training. To stealth successfully once it has been trained, don't wear anything heavier than Leather Armor or Mage Armor.
