Become Ethereal

 is a Dragon Shout in The Elder Scrolls V: Skyrim.

Effects
This shout makes the Dragonborn spectral in appearance and will make him/her invulnerable to all damage for the duration of the effect. In addition, stamina will not be depleted while this shout is active (but will not replenish while running). However, any damaging attacks performed while the shout is active will immediately end the effect.

Shouting additional words increases the duration and cooldown of the effect. A word of the shout can be meditated on with Paarthurnax to increase health regeneration while using the shout.

Situational Uses

 * Descend mountains quickly, as all fall damage is completely ignored.
 * Unlimited sprinting, as stamina drain is ignored.
 * Ignore all traps.
 * Provide a small window for uninterrupted Magicka regeneration.
 * Charge various master spells mid-battle without the risk of being interrupted (with the exception of Dragonhide).
 * Can be used to make enemy mages deplete their magicka while attacking you.
 * Can use any spell that only affects the caster.

Bugs

 * When the Dragonborn unequips the Ebony Mail and uses the shout and reequips it, the shadow effect then disappears.
 * Upon jumping into the water while using this shout, the Dragonborn may appear invisible.
 * While in water the model becomes "broken up" and it ceases to merge, making the lines of all the individual pieces in the model become visable.
