Ethereal (EU2012)

The Ethereals are some of, if not the most powerful alien creatures you will ever encounter in the game. These ancient aliens are the true masterminds behind the alien invasion. They are humanoid in form and possess four arms. While they are physically quite frail the Ethereals have the greatest psionic abilities seen in the entire game, using them to obliterate the minds and bodies of your squad.

Dr. Vahlen identifies a specimen to be centuries old. Despite this Ethereals actually have a ton of health. (20 hit points in total on Classic and below.) Do not expect them to turn into a pile of dust when you shoot them.

You will only find Ethereals in UFO assaults or on the final mission. They prefer to send their underlings such as Mutons to do their dirty work.

Tactical Advice

When you face these ancient aliens prepare for a very tough fight. Do not expect SHIVs to be immune to them. Ethereals can use pure psionic force against their foes instead of purely mind centered attacks. These attacks actually do more damage to SHIVs than to regular humans as SHIVs have no Will to defend them.

Ethereals will often only spawn on the bridge of UFOs. This gives you ample time to prepare for the fight beforehand. Just be sure you have cleared any aliens wandering outside. Make sure everyone has a full weapon and a meaningful turn to work with. When you open the door to the bridge you should take control of the Muton Elites there if possible, they make useful fodder units and provide a fair bit of firepower against the Ethereal.

Be advised that Ethereals actually have a chance to reflect projectiles and energy back at the attacker, fortunately for less than the weapon's base damage.

A squad at full capacity shooting at the Ethereal will often be enough to bring it down. Just be careful that it does not bring a few soldiers down with it!

Ethereal Councilor

These Ethereals are often seen commanding UFOs. Exercise extreme caution wherever these red robed fiends may be present. Heed the advice given above to bring them down.

Abilities:

• Psi Lance: Offensive Psi ability that deals more damage if the target fails a will challenge.
• Mindfray, offensive psionic ability that causes damage and lowers will/mobility/aim.
• Can Mind Control.
• Psi Drain: Drains up to 5 hitpoints worth of health from a friendly organic target. Cannot kill target(Can be used on mind-linked targets such as mind controlled squaddie)
• Rift, a powerful AoE attack that inflicts more damage if they fail a will challenge. It has the potential to do from 4 damage (if resisted) to 20+ (SHIV, since they have no will to resist.) Rift will persist on the map for one turn and damage anything that enters.
• Chance to reflect physical projectiles back at the attacker.
• High Will; resistant to psionic attacks.
• Ethereals explode upon death, dealing damage to all units within a fairly small radius.

This Ethereal commands the entire Alien Armada. He essentially has the same powers as regular Ethereals but the large stat bonuses he gains make him a formidable foe.
