How does magically enhancing your shield for defense enhancements & weapon enhancements work?
1. Would it be two seperate chains of enchantment i.e.
+2 (Defense Enhancement)4,000
+2 (Weapon Enhancement) 8,000
= 12,000
2. or a cumulative enhancment i.e.
+2 (Defense Enhancement) 4,000
+2 (Weapon Enhancement) +24,000 (the difference between +2 and +4)
= 28,000
My DM ruled #2 because it made the most sense to him, but also because the rules don't really cover this, but rather simply mention that you "can" enchant it as a weapon (pg 152 & pg 462). It doesn't actually describe how it works.
