As some of you might know, my main character is a Hierophant and I am slowly, but steadily going towards level 78. I was browsing the new skills I get at level 78 and the Power Ritual seemed like an interesting skill. It is an aura; thus, I assume it acts similarly to songs, dances, and the dwarven skills (e.g. Weapon Efficiency). On paper, it seems like a decent skill: +10% P. and M. Attack, +5% Attack and Cast Speed, +5% P. and M. Critical Chance etc. However, I've never seen other Hierophants use that skill. Is there a reason for that and should I spend my hard-earned Adena on that specific skill book?
