Which is better?

[Ruvanal]

Ethereal = [(Base+magic bonus)*1.5]*(%ed modifiers +1) + (+dmg modifiers)

Magic Bonus = 0 if weapon is not magical.
Magic Bonus = 1 if weapon is magical/unique/etc.

1.5 is from the 50% effecting base weapon damage from ethereal.

%ed modifiers encompases all listed enhance damage modifiers on weapon (IE Cruel, Ohm, etc.)

+dmg modifiers is all +min, +max, and "Adds x-y damage" modifiers.

The etheral bonus is applied to the base before the "+1 to base" that is applied to the weapons damage if there is enhanced damage on the weapon itself, not in sockets. Enhanced damage gained from items in sockets will be using the base damage (ethereal modifier does apply) without an "+1 to base" and each socketed items bonus to the total is calulated seperately before being added to the weapons total.
