Dreadful Carnage Vs Gory Finish

[Wraithcannon]

Are these feats basically the same thing?

Dreadful Carnage (Combat)
Slaying an enemy demoralizes your other nearby foes.

Prerequisites: Str 15, Power Attack, Furious Focus, base attack bonus +11.

Benefit: Whenever you reduce an enemy to 0 or fewer hit points, you can make an Intimidate check to demoralize all enemies within 30 feet as a free action. Enemies that cannot see both you and the enemy you reduced to 0 or fewer hit points are unaffected.

And

Gory Finish (Combat)
By drawing upon wells of savagery, you can slay your foe in creative and horrifyingly gruesome manners, intimidating nearby foes.

Prerequisites: Dazzling Display, Weapon Focus.

Benefit: When you use the attack action, you can use a weapon with which you have Weapon Focus to make a single attack at your highest base attack bonus. If you reduce your target to negative hit points, you can spend a swift action to make an Intimidate check to demoralize all foes within 30 feet who could see your attack.

Less restrictions for Dreadful Carnage but Gory Finsh you can have earlier. I guess my real question is, is there enough of a difference to justify having two feats for the same result? Couldn't we just pick one or the other and leave it at that?

Funny thing, the feat summary chart lists Dreadful Carnage's summary as, "Make a free Intimidate check when you knock down a foe", which I thought meant that if you trip an opponent you got the free intimidate.

That would make them totally different feats, instead of practical carbon copies.

You could view Gory Finish as an early version. Go with Gory Finish right after Dazzling Display, then retrain it to be Dreadful Carnage via Fighter retraining sometime at or after +11 BAB.

Dreadful carnage triggers whenever you kill something period. Even if during a Full Round Attack

Gory finish requires you to spend your standard action with one attack roll (hence the attack action as opposed to the FRAT) and then assuming you killed the opponent, get to do the intimidate check

It's a small difference yes, but it's a very important one, as one can be done as part of a FRAT, where the other one cannot.
