Consecration scale with AP or SP?

Basically what the title say
I am leveling with a friend and play as Holy..but sometimes I go out to farm some herbs alone and need to fight some mobs...I have a 2 Hand with me for that reason. I drop Consecration down, but how do I increase the damage of Consecration?
If it scales with AP, I can use Seal of Crusader and Blessing of Might...if not, I ll better use wisdom for more mana, or better equip a weapon with +Spell power?
