Dispelling Chances

According to the rules, the caster of a Dispel Magic or Dispel Evil (and a handful of other spells that refer to the chance of success Dispel Magic uses, notably Remove Curse), has a percentage chance to dispel the magic against which they are faced. The chance for a successful Dispell attempt is 50%, +5% per level of the Dispeller, but -5% per level of the caster of the magic being diepelled. I created a simple chart for fast reference (covering levels 1-10 for posting purposes since tables sizes can run off of the visible area):

So what does this look like for higher level clerics?

Well, just keep extending the charts.

A 15th Level Cleric Dispelling Evil against a 13 HD Demon's spell effects has a 60% chance of success.

A 12th Level Cleric dispelling effects from a 20th level Anti-cleric has a 10% chance of success.
