Does Warmage Edge's additional damage apply to the damage per round caused by the Wounding Spell metamagic when applied to an instantaneous duration damaging spell?
"If a spell deals damage for more than 1 round, it deals this extra damage in each round." per the Complete Arcane version of the Warmage base class.
"When affected by this feat, a spell that deals damage to a creature also inflicts a bleeding wound that does not heal normally. On each subsequent round, the victim loses 1 hit point at the beginning of your turn." per Wounding Spell from Lost Empires of Faerun.
Wounding Spell's text indicates that if the spell does damage, it continues doing damage per round. Which could mean "the spell deals for more than 1 round."
For this reason i suspect Warmage Edge applies to the bleeding each round, but have found no validation anywhere else.
