When a character attempts to use a skill, 1d100 is
rolled. If the roll is equal to or less than EML, the
skill has been successfully employed; if the roll is
greater than EML, the attempt has failed.
Any success roll ending with a five or zero is a CriticalSuccess. Any failure roll ending with a five or zero is a
Critical Failure. All non-critical results are Marginal.
The problem I'm having is determining if the last digit on the 1d100 is a five or zero. Or, alternatively, some other way of determing critical success/failure without throwing off the percentage chance. A straite 20% roll maybe?
Anyone lend me a few brain cells?
