S'mon said:My point: I think +7 or +8 to a stat (better than any non-artifact magic item can do!) for 15 hours is pretty bloody powerful for a 15th level cleric's spell!
And have you seen what the other spells are that a 15th level cleric has? Mass heal, holy aura, earthquake, fire storm, greater planar ally (summon a planetar, if not a solar, to do your bidding), empowered blade barrier, etc, etc. A triply-empowered bulls strength is the least of your worries.
Assuming you're not just laying out flamebait, after two years, you still seem to be having trouble readjusting to 3E. Stop torturing yourself. Go back to 2E, where you were happy.
