Calling upon the divine power of your patron, you imbue yourself with strength and skill in combat. Your base attack bonus becomes equal to your character level (which may give you additional attacks), you gain a +6 enhancement bonus to Strength, and you gain 1 temporary hit point per caster level.

Your height immediately doubles, and your weight increases by a factor of eight. This increase changes your size category to the next larger one, and you gain a +8 size bonus to Strength and a +4 size bonus to Constitution. You gain a +4 enhancement bonus to your natural armor. You gain damage reduction 5/evil (if you normally channel positive energy) or damage reduction 5/good (if you normally channel negative energy). At 12th level this damage reduction becomes 10/evil or 10/good, and at 15th level it becomes 15/evil or 15/good (the maximum). Your size modifier for AC and attacks changes as appropriate to your new size category. This spell doesn’t change your speed. Determine space and reach as appropriate to your new size.
If insufficient room is available for the desired growth, you attain the maximum possible size and may make a Strength check (using your increased Strength) to burst any enclosures in the process. If you fail, you are constrained without harm by the materials enclosing you— the spell cannot crush you by increasing your size.
All equipment you wear or carry is similarly enlarged by the spell. Melee and projectile weapons deal more damage. Other magical properties are not affected by this spell. Any enlarged item that leaves your possession (including a projectile or thrown weapon) instantly returns to its normal size. This means that thrown weapons deal their normal damage (projectiles deal damage based on the size of the weapon that fired them).
Multiple magical effects that increase size do not stack.

Divine Power gives a unnamed +1 per caster level. Righteous Might gives an enhancement to Constitution. Do these stack? Would you assume that the Divine Power is also an enhancement?

You mean +14, right?
Yes, these stack. Why would they? They aren't even different types of bonuses, they're different effects entirely.

No. Divine Power stacks with (some animals) endurance.
Aluvial said:What type of bonus is the temporary hps then?
TEMPORARY HIT POINTS
Certain effects give a character temporary hit points. When a character gains temporary hit points, note his current hit point total. When the temporary hit points go away the character’s hit points drop to his current hit point total. If the character’s hit points are below his current hit point total at that time, all the temporary hit points have already been lost and the character’s hit point total does not drop further.
When temporary hit points are lost, they cannot be restored as real hit points can be, even by magic.
Increases in Constitution Score and Current Hit Points: An increase in a character’s Constitution score, even a temporary one, can give her more hit points (an effective hit point increase), but these are not temporary hit points. They can be restored and they are not lost first as temporary hit points are.
