Weapon Damage Modifiers
|Exceptional||+4 (can stack on top of below modifiers)|
Weapon Accuracy Modifiers
|Accuracy Modifier||Bonus||Skill Increased|
|Accurate||+5||Tactics / Archery|
|Surpassingly Accurate||+10||Tactics / Archery|
|Eminently Accurately||+15||Tactics / Archery|
|Exceedingly Accurate||+20||Tactics / Archery|
|Supremely Accurate||+25||Tactics / Archery|
Note: Tactics is gained for melee weapons. Archery weapons gain additional Archery skill... ie.. Supremely Accurrate bow gives +25 Archery Skill. Although it is an 'Accuracy" modifier, it really only improves accuracy on Archery weapons. When Tactics is increased for melee weapons, it actually increases damage.
Weapon Durability Modifiers
Weapon Metal Colors
- Dull Copper
Metal types/colors for player made weapons only affects the durability of the weapon. It does not increase damage or accuracy. The only exception to this is weapons made with a Runic Hammer, which adds durability, damage, and accuracy modifiers based upon the color of the Runic Hammer.
