Nightmares of the Last War
These magical crystals can be attached to any piece of weapon or armour capable of containing its power. When touched to an item the crystal magically attaches itself and blends almost seamlessly with the design of the Weapon or Armour.
• A least augment crystal functions whenever attached to an
object of at least masterwork quality, even if the object itself
has no magical properties.
• A lesser augment crystal functions only when attached to an
object with a magical enhancement bonus of +1 or higher (such
as a +1 longsword or bracers of armor +1).
• A Greater A lesser augment crystal functions only when attached to an
object with a magical enhancement bonus of +3 or higher, this refers to the actual enhancement bonus, excluding any enhancements ( a +3 longsword is valid whereas a +1 keen longsword would not be.)
Only one crystal can be attached to an item.
Weapon crystals can be attached to any melee or ranged weapon that qualifies as above. Energy assault crystals cannot be attached to a weapon that is already enchanted with the same element.
Armour crystals can be attached to any armour, shield or bracers of armour that qualify as above.
Multiple crystals with the same effect do not stack but they do overlap. for example two lesser iron guard crystals would still only grant Damage Reduction 3/-, not DR 6/-. one would absorb the first 30 points of damage then the other would activate when the first has become inert.
