Tremor

Tremor - later known as Earthquake - is one of the most destructive spells known to the mages of Britannia.

Spell Description
This spell is a truly potent weapon. Casting Tremor will set off a horrible earthquake that rumbles the ground and causes gaps in the ground to open. The caster's foes will be frozen in terror, lose their footing and if falling rocks don't kill them, they will be swallowed by growing gaps in the ground, never to be seen again. This spell cannot be cast in settled areas, as it would cause death on a massive scale, so its use in such a way is thus strictly forbidden.

Lore




Trivia

 * In Ultima VII the spell has little use, since it only causes the screen to shake, neither doing damage nor demoralizing the enemies. In fact, it actually can cause the game to lock-up if one is really unfortunate.
 * This spell is best used in Ultima IV to clean out dungeon rooms, as it is one of the few spells that doesn't need line of sight to work as intended.
 * In Pagan the spell is known as Call Quake and is part of the magic school of Necromancy.
