Sacred Light  

It's nice to have a new heal spell, especially since player's HP pools are increasing, but this does not seem all that great when compared to lower spells.

Pious light:
lvl 68
cast time 3.8 (this is 3.75)
mana cost 740
Heal 3770hp

So for .05 faster casting, 55 more mana, and 490 more hp of healing, EQ considers this notch up for clerics after 5 lvls. (5.1hp vs 5.3hp per mana).

I will use this spell becasue fast and hard hits require bigger heals, but it seems EQ could have done better than turning the lvl 68 spell into the lvl 73 spell with a small tweak, of giving a little less than 100hp gain per lvl, until you reached 73, and were able to cast this spell.
