Brilliant Energy, Variant (3.5e Equipment)

''You may be looking for the flawed SRD Brilliant Energy enhancement. This one is homebrew.''

Brilliant Energy, Variant
Summary::The business end of your weapon transforms into solid light, passing through armor and striking at the creature's life essence directly. This does not modify the item’s weight. It always gives off light as a torch (20-foot radius).

This weapon ignores armor and shield bonuses to AC, and ignore half of natural armor bonuses. It can strike incorporeal creatures as if it were ghost touch. It can still hit non-living objects (such as constructs, undead, and attempting to break a sword) but with less effectively as it strikes out at its elemental spirit, negative energy force, or general omnipresent energy which exists in nature. Against non-living objects or creatures it deals half damage. Because it is made out of light, it deals +50% additional damage against creatures vulnerable to light.

As the same action to draw or sheathe a weapon you can collapse a brilliant energy weapon into a compact form, typically only the hilt of the weapon or a small rod. It decreases two size categories for the purposes of storing it away, and may be grown or shrunk as part of the action of drawing or sheathing the weapon. The brilliant energy effect may also be toggled on or off as a standard action.
