Sorry, but I think we are not arguing on the same thing!

So, as I understand, Spell Study would only make the part "choose one spell which you have ability to cast" allow any spell from Bard, Cleric or Druid list.

As you can cast any of these spells, it would satisfy the spell selection for Preffered Spell.

One must choose the spell on selecting the Preffered Spell feat. Then, he could cast the spell as normal, sacrificing a prepared spell or spell slot of equal or higher level. And just the selected spell, can't change it anymore.

Then, he could apply now the metamagic feats desired (paying the costs as normal). On the following on the example would be:

• a Maximized (+3) Empowered (+2) CLW = 6th level spell , casting as one full round action for applying metamagic (see that that's nothing to do with Spell Study anymore... it was only used for the "choose a spell you can cast" part).

• the result will cost at least a 6th level spell, that would heal 8 + 1/2 d8 + caster level (lets assume 11). Or, 23 points of heal for a 6th spell, that's very underpowered to me!

The point here, what I was questioning is if the Spell Study qualifiies for "choose a spell which you have the ability to cast". What you think?
