* The good is that it raises a weapon's damage 50%, and an armor's defense 50%.

So an Ethereal weapon will potentially have the biggest damage of any weapon in the game, but it wouldn't last long. Armor can be usable indefinitely with Ethereal on it, depending on how often your character gets hit, and the added Defense can help, but very few characters select their armor based on it adding higher defense, and the ones that do are the ones who need higher defense, I.E. they are getting hit a lot.
