A player has asked me about this portion of the spell:
"Spells and spell-like effects targeted on you are turned back upon the original caster. The abjuration turns only spells that have you as a target. Effect and area spells are not affected. Spell turning also fails to stop touch range spells. From seven to ten (1d4+6) spell levels are affected by the turning. The exact number is rolled secretly."
We're a little lost on the 'Effect' part of 'Effect and area spells.'
We know it doesn't effect ranged touch attacks, AOEs, spells that target more than one person, but that part is throwing us for a loop. All spells have effects, so what does that entail?
