Greater Magic Weapon and the Bane property?

[Venator]

You all seem a lot more sure than I am that the bane property increases the +5 to +7 and not the +1 to +3, which doesn't stack with the +5.

yeah, this is why i posted the question. the word "normal" in the Bane description was the problem. Does casting GWM change the weapons "normal" enhancment bonus?

 

[Venator]

Actually, it does both.

You now have a sword with a +3 and a +7 enhancement bonus, which don't stack.

I am cool with this ruling (and agree with it), but can you please post why you feel this way?

The enhancement bonus of the weapon is either +1 or +5. Bane simply increases the enhancement by +2 vs. undead. The source of the enhancement doesn't matter.
