I think you have to go to the base spell, Align Weapon

ALIGN WEAPON

School transmutation [see text]; Level cleric 2
Casting Time 1 standard action
Components V, S, DF

Target weapon touched or 50 projectiles (all of which must be together at the time of casting)
Duration 1 min./level

Align weapon makes a weapon chaotic, evil, good, or lawful, as you choose. A weapon that is aligned can bypass the damage reduction of certain creatures. This spell has no effect on a weapon that already has an alignment.

You can't cast this spell on a natural weapon, such as an unarmed strike. When you make a weapon chaotic, evil, good, or lawful, align weapon is a chaotic, evil, good, or lawful spell, respectively.

It would also be an oil which you apply, not a potion which you drink.

A level of bloodrager could help with dr good.

[Ji-kun]

Bloodrager with the cleestial bloodline is a good class to dip into if you don't want to pay for Holy. Too bad it's only limited to outsider until you get Holy.

Any recommendations to help Marl defeat DR/Good with his natural attacks?
