Could you use Swift Alchemy (immediate action to poison a weapon) as part of an AoO?


Round 3: Alchemist and Inquisitor


Title says it all...


after reading what a swift action is, i wouldn't see why you couldn't. any time you can take a free action you can take a swift action, as long as its just once this turn.

No... an Attack of Opportunity is the taking advantage of a sudden opening up of defense in melee combat. it's assumed that during the combat round you've been swinging, thrusting, parrying etc. and the AOO results from a momentary lack of defense on the opponent's part and a momentary advantage given to the attacker which can only be used for an attack action.

Ummmmm, that would be true except it says it's an "immediate action"...would that not impact this?

In general you can only take an immediate action on your turn.

I think the whole point of an immediate action actually is that it's like a swift but you can do it on other people's turns...check me on that according to the book.

I checked the book...

immediate actions take up your use of a swift action as they count as a use of a swift action but can be done any time... the example given is feather fall. if you use an immediate action when not your turn, you can not use a swift action (including an immediate action) on your next turn.

I don't see why you can't.

1. Opponent provokes attack of opportunity (no action)

2. Alchemist uses immediate action to poison weapon (1 swift action, allowed out of turn, uses up next turn's swift action.)

3. Alchemist makes attack of opportunity (uses no action).

This assumes the alchemist isn't flat-footed or has Combat Reflexes.

I think it is doable... but a bit clunky mechanically

That is how the rules swing it!

I was under the impression Swift actions could only be done on your turn and Immediate actions could be done on yours and your opponents. The rules even specify the different speeds you can do it at.

3rd - Swift Alchemy (Poison as a move action)
6th - Swift Poisoning (Poison as a swift action)
18th - Instant Alchemy (Poison as an immediate action)

If you're poisoning that much stuff by 18th level I'll be surprised if you haven't taken the Sticky Poison discovery giving you probably 5-7 hits worth of poison.

Lets try this again. An attack of opportunity is NOT defined as free immediate action it is defined as below from the PFSRD:

Making an Attack of Opportunity

An attack of opportunity is a single melee attack, and most characters can only make one per round. You don't have to make an attack of opportunity if you don't want to. You make your attack of opportunity at your normal attack bonus, even if you've already attacked in the round.

That's it in the bold folks. the only thing you can do for an AOO is a SINGLE MELEE ATTACK. no quick poison of weapons, no quickened spells, nada else. Now you can take an immediate action any time you want outside of your turn, but that's your swift action for next round and you do not get a bonus or free immediate as part of an AOO, also the Immediate can not be combined with another action.


The title of the thread makes this matter confusing. You CAN'T use Swift Alchemy to poison a weapon for a AoO because Swift Alchemy is a move action to poison and can only be performed on your turn. You CAN use Instant Alchemy to poison a weapon for an AoO (indeed I'm sure that's the whole point of the ability) as that is an immediate action that can be taken just before the AoO. It's not PART of the AoO, but it can interrupt the series of events that ends with the opponent taking damage (hopefully) from the AoO.

Ahhh true, I am sorry to have confused this - when I posted "swift alchemy" I was thinking the entire ability was called that (all class levels up to 18th were included under the heading).

So here's the answer everyone - yes, you can use Instant Alchemy to poison it before taking the attack - the "single melee attack" post above from Lazarx is incorrect, because yes an AoO is for a single attack but at 18th level you can poison as an immediate action doing so immediately before.

Thanks all.
