One shot kill

[Cory Stafford 29]

Looking at the dastardly finish feat coup de grace cowering or stunned opponents), it seems like it would be neat to make a character that could get a lot of use out of it. It requires +5d6 sneak attack, so you need a lot of ninja or rogue levels. I was wondering about the best way to get the enemy cowering or stunned with this type of character.

Stunned is easier if you have a caster friend. Also look into the 3.5 feat Death Blow - it allows you to do a Coup de gras as a standard action.

I am well aware of the fact that casters or monks can get enemies stunned easier, but I was wanting a way where the PC wouldn't have to rely on others. He'll accetpt help from others, but I don't want him to depend on it. I would also prefer to stick with Pathfinder material as opposed to 3.5 stuff.

Vivisectionist is another option.

Pick up stunning fist at 11, or go vivisectionist/internal alc to get it as a discovery.
Or ignore dastard, and go ninja assassinate instead.
Rogue or whitehairwitch with a familiar UMDing a staff with power word stun?
A quickdraw shield with symbol of stunning on it.

This also depends on what you want to kill in this fashion.

Is this for an AP?

What is your point buy?

What races are available?

[Cory Stafford 29]

Nothing specific. I just wanted to see if there was a way to make a character be able to reliably use the feat. Basically, theorycrafting. I would say a 20 point buy. Standard races plus maybe tieflings and aasimars. Standard wealth by level. 10th-12th level PC.

It's tough to find a non-caster/non-ally way to make it work because most stuns are 1 round only so they cannot be combined with a dastardly finsh action. There are some feats which can multi-round stun or fear, but they require a BAB 16+ which is going to be tough for a character with rogue(ninja) 5 / master spy 1 / assassin 1. There is a magic item (hellscourge, a whip with the affiliated feat tax) which can do it but it is expensive and unreliable (hit once and fails save to frighten, hit second time in same round and fails save to cower, 75% chance to not have cower only last 1 round, and you have to combine it with an intimidate build of some kiind to produce the shaken effect.)

Combine stunning fist with panther or snake or crane, stun on the AoO and dastard on your turn.
