Summon

Summon is a spell that calls forth a powerful creature to aid the caster. This is a truly potent spell, but it also has to be used with much caution. The downside of this spell is that once the caster's enemies have been defeated, the creature, annoyed at being summoned, will turn against the spellcaster.

Originally, casting this spell summoned deadly daemons to destroy the enemies of the spellcaster. However, from Ultima VII onwards, the spell summons other powerful creatures like dragons. The reasons for the change is unknown.
