Archer Skill Guide

Sharp Eyes

Sharp Eyes is high priority to the Fourth Job Archer as it steadily increases in power each level and every point increases the duration for an extra ten seconds. Anytime a Mastery Book is obtained focus on putting points in this book should highly considered.

This is misleading; even though it does steadily increase, the difference in damage alone from level 1-30 is only +29%(+111% at level 1, +140% at level 30). After SE lasts a decent ammount of time it's more useful to any archer to max expertise for more stable damage and, then go on to hurricane(not sure where a MM would go).
