Summon monster question: Celestial vs. Fiendish

[Nail]

Our game (I play a Clr that summons) has allowed switching alignment templates. As my PC is NG, his summoned spiders are celestial.

To expand, I had a DM who went through and did this. He also included the other MotP templates (Shadow, Axiomatic, etc.). Additionally, every sorceror chose a bloodline (either alignment- or elemental-related), and sorcerors were limited to summons from their particular bloodline. Wizards, upon learning a Summon Monster Y spell for the first time, could choose two bloodlines, and could relearn the spell (as if it were a new spell) to add additional bloodlines (one each), or could learn the additional bloodlines from another wizard.

Yoink!

Flexibility is power, and by expanding the cleric's summoning list, you do increase his power significantly.

Certain animals have advantages in certain situations; rhino vs. foes with high DR, dire bear vs. spellcasters, dire bat vs. invisible foes, etc. Using the lists strictly as they appear in the PHB, the abilities of good/evil divine casters are somewhat constrained by not having access to everything.
