I have a few questions about this enchantment since one of my players asked about it.
1) Does the weapons enchantment bonus include all bonuses? IE is it capped at +5 from the weapon gaining +5 to hit/damage or does it include all enchantments like itself and flaming (max +10)
2) What damage does each orb do? The player makes a point that unlike flamings infinite 1d6, this is only once/day. The CL of this enchantment is 10th, which I realize is mainly for crafting it. Does each orb deal 1d8 or 5d8 or somewhere in between?
1) It uses the actual + modifier that is not being used up by special qualities. So if it were a +2 Beaming Flaming weapon (priced as a +4), the Beaming enchantment produces two orbs.
2) It uses the caster level of the enchantment or the weapon, whichever is higher. So in this case, it deals 5d8 to most targets, 10d6 to undead, 10d8 to light-vulnerable undead, and 5d6 to constructs and objects.
