Luck

From dodWiki

Luck (LCK in your 'score') represents the tendency of a character to succeed or prosper through chance or good fortune. As in life, the exact extent of this factor remains and will always remain shrouded in uncertainty...

Also as in life, however, it can be said with surety psychic reading that its influence on a character is pervasive. Though it affects some aspects of life here in a very direct manner, it can affect nearly every aspect to at least a degree.

No class receives luck as a prime attribute.
