By "not stacking" would that mean not working upon the same weapon at all, or the Bless Weapon effect only applying on rolls within the weapon's un-enchanted threat range?
That is, say you cast Bless Weapon on a +1 Keen Scimitar. Does it:
A) Simply have no effect?
B) Automatically confirm criticals rolled on an 18-20, but have no effect on threats rolled on a 15-17?
The automatic confirm effect does not work on any weapon that has a critical altering magical effect applied to it.
Says right here:
In addition, all critical hit rolls against evil foes are automatically successful, so every threat is a critical hit. This last effect does not apply to any weapon that already has a magical effect related to critical hits, such as a keen weapon or a vorpal sword.
Huh. Apparently this forum doesn't do underlines.
Oh, last I read it, the spell said it didn't stack with effects that affected crit range. Nevermind.
