Bane Weapons and Epic DR

[Dragon Mage]

Is there anything in RAW in regards to a Bane weapon penetrating Epic DR if the enhancement bonus of the weapon is greater than +5 when the weapon's bane enhancment is on. For example a +4 Dragon Bane weapon is +6 when wielded vs. a dragon. Will this allow it to penetrate the DR 15/Epic a Force Dragon has?

Thanks for the help, and sorry if the has been addressed already.

In order to beat Epic DR, you need an Epic weapon.

An Epic weapon is one with an enhancement bonus of +6 or better.

A +4 dragonbane weapon has a +6 enhancement bonus against dragons.

Therefore, a +4 dragonbane weapon will beat a dragon's DR X/Epic.

What PoE said.

This is the only way to penetrate epic DR without an actual epic weapon to the best of my knowledge.

Patryn is right. Straight for the SRD:

A few very powerful monsters are vulnerable only to epic weapons; that is, magic weapons with at least a +6 enhancement bonus.
