Is there much point raising anything other than weapon skills & disruption? i.e. do the other casting skills effect songs?
Ministration controls one spell Speech of Sacrifice and should reduce the power cost of the spell as ministration is raised. Certainly not a biggie. Ordination controls buffs /debuffs. The biggest advanatage of maxing it is mobs will resist your debuffs less. It has no effect on casting buffs that I am aware of. Subjugation controls one spell Wail of Horror and should also reduce resists as it is raised. Ordination is definitely worth maxing, the other two would depend on your play style. My play style easily maxed Ministration but my Subjugation is 24 as Wail of Horror is rarely cast. Duubard
