Altair

The Sosarian arcane spell Altair is perhaps one of the greatest accomplishments of the mages.

Spell Description
Casting the spell has the same effect as Articles to Negate Time and freezes time around the caster and the party for some moments, enough to either start a tactical retreat, or to strike down the foes while they can't move. Either way, it is a very powerful spell. However, the sheer drain on the mana pool prevents it from being used too often, as it is very taxing on the caster. Keep this in mind, or you'll be unable to cast it, when really needed.

The spell did evolve in britannia into the spell Time Stop.
