So Elemental (fire), Elemental (Ice), and Elemental (Lightning) clerics each get Thunderwave and Lightning Bolt? Is this a mistake or is it intentional?
Elemental Domain Spells: In your list and always prepared.
Level 1: Thunderwave, Fog Cloud
Level 3: Levitate, Misty Step
Level 5: Lightning Bolt, Fly
Looking at the SRD spell list, I can see why thunder and lightning might have been chosen. Not too many ice and fire choices in SRD at spell levels 1-3. Still, it seems a bit strange.
