The Atronach Altar is located in Frostcrag Spire's main level. It is only available through the Wizard's Tower DLC.

You can offer 3 kinds of salts here to summon a permanent atronach familiar:

• 3 Void Salts for a Storm Atronach
• 3 Fire Salts for a Flame Atronach
• 3 Frost Salts for a Frost Atronach

You can also summon another creature in addition to the atronach, using regular Conjuration, thus it is possible to get more than 1 familiar at one time.

The Atronach can be dismissed whenever you choose so by talking to it.

There are reports of a particular glitch/bug that makes your atronach's body freeze on spot after its death.

This cannot be fixed, but means no harm; you can still summon another one.

Only one atronach may be summoned from the altar at one time. However, it is possible to summon multiple atronachs by using the console:

• Using the console you can kill an atronach summoned by the atronach altar, summon another atronach and then resurrect the first one (using the console again) and thus have multiple atronachs at once.
