Luck

Luck is a runic spell that appears in Ultima Underworld II.

Description
The exact workings of the Luck spell are never made clear, although this cantrip is said to improve its casters chances in a melee - most likely allowing them either a greater chance of landing a blow or a lessened chance of being struck. It appears to be functionally similar to the spell, Curse, which thwarts the fortunes of nearby enemies.
