A spell against an enemy with In 4 always does 999 damage, because its magic defense works out to 0. Below 4 the number wraps around, and the defense jumps to about 189.

The critical hit code has a second check meant for a rarer kind of critical, but it only runs after the first check has failed against a bigger number, so it can never pass. There is only one kind of critical hit.
