Which is better?

[FenrisWulf]

I'll follow up where Archon Wing left off. The Ethereal one is guaranteed to add an approximately equal or greater amount of damage. Why? Because, roughly, being Ethereal adds 50% to the base damage of the weapon, while the Ohm adds 50% damage based on the base damage of the weapon. Thus, in the case that there is no existing +% ED Mod, then the damages will be the same (or slightly different; I forgot whether Ethereal does the 1-1 thing). However, if there is any +% ED, the Ethereal bonus will be applied before this (meaning it will be boosted by the existing +% ED), while the Ohm bonus will be applied at the same time as the existing +% ED.

ie, ethereal >= Ohm.

Let me know if that makes sense, and if I screwed anything up along the way.
