PowerWyrm is on a distinguished road
OF_AFRAID adds a flat 20% fail to the rate, which is the base spell failure rate minus the bonus from INT minus the bonus for "easy" spells (level < clvl). The result is capped vs the minimum/maximum failure rates. Because of these caps, the effect of OF_AFRAID is marginal, that's why using rings of escaping with a spellcaster is great. It's basically the same as a priest using a pointy weapon. Would be much less useful if the penalty was applied after the cap, like for example when the character is stunned.
