Ethereal

Ethereal is a powerful water-based wand, with a minimum level of 70. It relies heavily on large spell damage and mana bonuses to deal rapid damage; in addition, it gives several bonuses boosting the chance of dodging and avoiding damage you might take.

Lore
"Supposedly based off of the wand of master mage Ethe, this wand is plated with magic-focusing jewels and heavy gold, yet somehow remains entirely weightless."

Trivia

 * Prior to the 1.14 Gavel Expansion, Ethereal was the second most powerful Wand in the game (after Bob's Mythic Wand).
 * Ethereal is the only of the four "master" weapons (Maelstrom, Fierte, Chakram and Ethereal) to reference its associated master in its lore.
