Excuun

Excuun is a tremerndously powerful attack spell.

Spell Description
Of the attack spells available to the cleric, Excuun is the strongest against a single foe. Casting it sends a beam of pure holy force against the foe, whose natural darkness and therefore its life, will be eradicated. Only the strongest foes can hope to survive this attack, whose power against a single foe is unmatched. Note that it is similar to the mage's spell Decorp, while Zxkuqyb enables the cleric to attack multiple foes with this attack.

This spell together with Decorp would in Britannia evolve into the Kill spell.
