Spellcasting
Chance to Cast
( Gathered from Wilki's statements in http://boards.stratics.com/php-bin/uo/showflat.php?Cat=&Number=7087151 )
- ChanceToCast = ( ( Skill - ( Difficulty - ( Focus / 2 ) ) ) / Focus )%
- Chance to Cast can never be negative, nor over 100%.
- The Minimum Skill Requirement to cast a spell exists two ways:
- For Chivalry, Magery, and Necromancy: MinimumRequirement = ( Difficulty - ( Focus / 2 ) )
- For Everything Else: MinimumRequirement = ( ( Difficulty - ( Focus / 2) ) + ( ( Focus * 5 ) / 20 ) )
Definitions
- Skill: The caster's skill level.
- Difficulty: the point where you have 50% to succeed
- Focus: How wide the "window" is between 0-100%, centered on the difficulty value
- Minimum Requirement: Minimum skill level required before spell can be cast (even if the chance to cast is above 0)
