Elemental Power [Synergy] D&D 3.5

[JasonP]

So I was looking in the DMGII and saw the Air/Earth/Fire/Water Elemental Power weapon enchantments. They all require a +1 enchantment of elemental damage of the same type as the elemental power to put the enchant on it and it allows you to summon an elemental for a certain number of rounds, once a day.

Can anyone tell me what enchantment I should add if I want to put a Shadow Elemental Power enchantment on a weapon? The only one that sounds right to me would be Ghost Touch maybe.

Also, has anyone used the Elemental Power enchants and can tell me if they are even worthwhile? I will be playing a Dark Whisper Gnome Beguiler if that helps.

Anyone?
I figured that this would either be an easy one or a tough one. Guess it's the latter.

There are Shadow-based magic weapon properties in Magic Item Compendium, and Tome of Magic.

Which also has Shadow elementals, and Shadow genies.

So it would go quite well with that.

The only weapon property I see that is specifically shadow in the Magic Item Compendium is Shadowstrike which is 5,000gp (a little more than +2) don't think quite works and in Tome of Magic there is only Shadow Striking which is +3. Am I missing something?

Yes Shadow elementals work perfect for this, I got the idea because I had already read about them.

There is a distinct lack of "shadow" and "shadowy burst" weapons.

Given that shadow elementals do cold damage, maybe a refluffed Frost and Frost Burst would do?

Profane and Profane Burst are more negative energy than shadow.
