Bless Weapon shows up in spells, but not in temp bonuses.
Just going to say, there isn't anything to "Code" for the Temp Bonus. Bless Weapon doesn't actually change the values of the weapon, which is why there has never been a temp bonus. However, I've added the CombatBonus text, and am attempting to allow you to select a weapon, but beyond that, not much else I can do.
Okay, if you want the text, you need to select yourself. If you want to select a weapon, you choose a weapon. If you want both to display, you need to add BOTH.
