The Mana Cost of each special move can be reduced if the warrior's skills are high enough. Add up the skill points for Swords, Mace Fighting, Fencing, Archery, Parrying, Lumberjacking, Stealth, Poisoning, Bushido and Ninjitsu. If the total lies between 200 and 299, subtract 5 from the Mana Cost. If the total is 300 or more, subtract 10 from the Mana Cost. Some items have a property called "reduced mana cost". These items also reduce the Mana Cost of these Special Moves. --------------------- So let's use AI for example. if I reduce the cost by 10, it is LMC of 33%. (cost 20 instead of 30). if I have LMC 40% on will it cost me 18 mana or 12 mana?
