The text of divine bond explicitly says that it cannot bypass the +5 enhancement bonus cap of a weapon. However, the rules also say that a non-epic weapon can only have a total effective enhancement bonus of +10, but this is not mentioned in the divine bond text.
My question is does the divine bond ability allow the paladin to exceed this cap, or is any enhancement above and beyond the +10 cap effectively wasted?
Well, my point was that divine bond explicitly says it cannot exceed the +5 Cap but makes no mention of the +10 cap. I'm just curious because if a Paladin's weapon can't be enhanced beyond +10, I'm not sure it's really worth it for a Paladin to have more than +4 bonus to their weapon without Divine Bond.
