Weapon enchantment/buffing question
1) Could you cast Keen Edge (or Weapon of Impact, its bludgeoning counterpart) on a magical weapon that had already been enchanted up to the +10 non-epic maximum? In other words, could you create a situation in which your weapon was effectively +11 or +12 temporarily via weapon buffing spells?
Yes, you can.
To illustrate the question by example:
You can, by the rules (I think), have a +2 shocking burst (+2), flaming burst (+2), icy burst (+2), holy (+2), (total +10 enhancements) Great Axe Lets say I have this Great Axe with a +10 total enchantment (Sweet!). Now, can I have my wizard friend cast Keen Edge on it? -OR- since the weapon cannot be crafted with more than 10 pluses of bonuses without essentially being an Artifact, is it in some way capped out? The same question applies if I am using a Scabbard of Keen Edges (which allows for the Keen Edge Spell to be applied to your weapon 3 times a day.)
You cannot *create* a weapon with more +10, but that does not mean a weapon cannot *be* more than +10 temporarily. Note, however, that enhancement bonuses from spells still don't stack with a magic weapon's magical enhancement bonus. A +2 flaming, speed sword that receives a +3 enhancement bonus from a greater magic weapon spell becomes a +3 flaming, speed sword.
