Item Materials
 
    So far I have discovered 17 different item materials in Natuk.  Some do not affect the item in a manner directly useful to combat, but rather increase it's value, or reduce it's weight.  Some materials have more than one property.  When a bonus is granted, it is granted only to the item in question (not the whole inventory : )  ).  A note about Cold-Iron items: Cold-Iron might be a bit hard to understand at first (and my description in the table isn't the best  : )  ), but basicaly it gives you a bonus to Magic Resistance of +2, then it gives you an extra bonus of +2 for each "+" that the item has.  For example: a +2 Cold-Iron Dagger would give you a bonus of +6 to your Magic Resistance (+2 for basic Cold-Iron bonus, +4 for two magickal "pluses")
