Notes:

* The shared spell power (higher of Light and Elemental) granted by elemental domains to "spells" does not seem to extend to non-spell effects, such as Arcane Archer damage or Warlock pact damage (DDO Forums). It also does not apply to spell critical chance.

† Mephits are outsiders, not elementals. Therefore, elemental domains don't grant the ability to turn mephits.
