Thanee said:Not really. The cleric's ability only allows him or her to cast a cure spell instead of a prepared spell. This has absolutely no benefit to a sorcerer, unless one feat is spent on Arcane Preparation.
Even then, just because it allows to cast a cure spell instead of another spell doesn't lift the requirement to be able to cast the cure spell in the first place.
And the limit for Arcane Disciple would also still apply, so you could only do this Wis bonus times per day (Spontaneous Healer) and also only cast one spell of each level from the domain each day (Arcane Disciple).
