OK, you declare an OB/DB split, out of your skill.
Various spells, magic weapons all grant bonuses. . .
But almost all are bonuses applied to just OB of attacker, or just DB of the defender, after the split is declared.
This came to mind based on the discussion here:
http://www.ironcrown.com/ICEforums/index.php?topic=10519.0
That (using RMC bonuses, but the logic applies with RMSS also):
Broadsword +10 OB (Enchanted with Weapon II)
is a different magic item than
Broadsword +10 Skill (Enchanted with General II)
In that if Gronk, with a +50 Bonus in Broadsword skill is using one or the other, with the +10 OB weapon he could at most extreme declare an OB/DB split of 0/50, then it's 10/50 with the Weapon II bonus.
But using the 2nd sword of +10 skill, he has 60 points of skill to split, so could go 0/60 with all the bonus to DB.
Or would you allow magic bonus or quality bonus to a weapon to be used on the DB side?
