Can you combine a Coup d' Grace withs attack from feats

[Tsukishijin]

I've recently started playing a Rage Prophet and I've been thinking about what to do if I find myself in melee against a more dedicated fighter. At this time I don't have a lot of offensive spells (and as my spellcasting is from the Oracle with battle mystery I won't have a lot of them). Now I could buff the crap out of myself but a thought I had was this: use Hold Person as a readied action, set to activate if the melee person steps within 10 feet of me (low Will saves usuallly) and then coup d' grace.

I'm pretty sure this is legal.

What I'm wondering is on the accompanying Fort save can you use a feat like Vital Strike or Power Attack to up the damage?

Note that coup de grace is a full round action.

And no, I do not think that you can power attack or vital strike on a coup de grace.

By RAW no you cannot use either of those.

Power attack requires you to declare it before an attack roll, and with a coup d' grace you don't roll an attack roll.

Vital Strike requires you to use an attack action, which a coup d' grace is not an attack action, just like spring attack does not let you use vicious strike either.

My group allows it but it is not technically legal.

I am aware that it is a full round action. At 10 feet I should be able to take a 5 foot step and be in range. Or would readying the action mean that I would need to wait another round after casting (effectively giving him two saves)?

Yes. You would need to wait for the next round before issuing the coup de grace. But, if you have a friend nearby, *THEY* could deliver the blow on their turn.

No you would act just before his next action, so he'd only get the initial will save, unless of coarse he makes his fort save and doesn't die then he'd get to make another will save as a full round action.

Well, technically, the start of your turn IS before making an attack roll.

I think the intent was that you can't make an attack and THEN turn on Power Attack.

Except now I'm not sure.

"You must choose to use this feat before making an attack roll, and its effects last until your next turn."

Can you make an attack (Say, full-BAB iterative) and then turn on power attack for your second (BAB-5 iterative) attack (and any AoOs etc.) ?

It's still being used before making an attack roll. That would mean you can attack normally, then just turn on PA for AoOs.

For CdG, what if someone had a readied action to ... move or cast or something, triggered by the start of your turn. Your turn starts, the readied action triggers, they provoke, you turn on Power Attack for your AoO. Now you use a full-round action to CdG. Does Power Attack still apply? If so, then you should be able to just turn it on normally. If not, then there should be some exception written about what kind of damage bonuses apply to a CdG.
