Exceptional is a tag which may be given to items made by a crafter of sufficient skill. It adds bonuses to Weapons and Armor that may be furthermore enhanced by using Runic Tools.
If a Grand Master or above creates an Exceptional item, it may furthermore receive their Maker's Mark.
An exceptionally made piece of Armor will gain a 15% bonus that is distributed randomly among the base resistances of that item. For example, an exceptionally made Platemail Tunic could have 5% applied to Physical, 6% to Fire, and 2% to each Cold and Poison. Or, and this would be extremely rare, all 15% could be added to Physical.
Exceptionally crafted armor also receives an additional 1% bonus (again randomly distributed) for every 20 points of Arms Lore your character has. The maximum bonus is therefore 20%. However, the total additional points from Exceptional and Arms Lore is capped at 20%.
Exceptionally crafted Weapons get a 35% Damage Increase bonus as a free Item Property.
This is boosted by 1% for every 20 points of Arms Lore your character has. The maximum bonus is therefore 40%.
Charged items (such as Tools) will have more uses attached to them if crafted exceptionally. Items such as furniture receive no benefits other then the Maker's Mark.
