Interesting take.It doesn't get the ability modifier to damage because the spell states exactly it does 2d8 damage not that it does 2d8 damage +ability modifier. ...But Yes, its 2d8 and more then damage on average than a 1d6+5 which is my point.
Since it counts as a simple melee weapon, I would certainly add the ability modifier when it is the first weapon. After all, don't you add the ability modifier to the attack roll? If so, you should apply it to the damage roll as well IMO.
