Grapple weapon and weapon traits (not finesse).

[shroudb]

I'm not sure if that has been clarified anywhere, or what is the concencus.

Relevant traits/actions:

Attack trait (from Grapple action)

Quote:

An ability with this trait involves an attack. For each attack you make beyond the first on your turn, you take a multiple attack penalty.

Grapple trait:

Quote:

You can use this weapon to Grapple with the Athletics skill even if you don't have a free hand.

Forceful trait:

Quote:

When you attack with it more than once on your turn, the second attack gains a circumstance bonus to damage equal to the number of weapon damage dice, and each subsequent attack gains a circumstance bonus to damage equal to double the number of weapon damage dice.

Backswing trait:

Quote:

You can use the momentum from a missed attack with this weapon to lead into your next attack. After missing with this weapon on your turn, you gain a +1 circumstance bonus to your next attack with this weapon before the end of your turn.

Agile trait:

Quote:

The multiple attack penalty you take with this weapon on the second attack on your turn is –4 instead of –5, and –8 instead of –10 on the third and subsequent attacks in the turn.

So, overall, the way i see it:

Unlike finesse, all those traits only mention "attack" not "attack roll". And grapple action is an Attack as described in the attack trait.

So, if you are using a Grapple weapon, which specifically uses the weapon for the attack, then do the rest of the traits activate?

As an example, if you first do a grapple check, and then you swing with the weapon, does the swing gets the bonus from the Forcefull since it's the "second attack with the weapon"?

How about if you miss the grapple, does the attack gets the bonus from the Backswing trait?

Same thing with Agile, does it means that if you swing first and then go for a grapple, does the grapple gets a -4 MAP instead of a -5?

The Finesse clarification was because some people thought attack roll also covered skill check.

The traits you mention do not deal with this, so I would say yes to all.

You might be able to consider "miss" a term specific to attack rolls, so a failure on a Grapple check with a Grapple weapon might not count as a "miss." I'd allow it, personally, though.

Not mentioned but worth noting is that a damage bonus requires a damage roll (or a non-roll instance of damage), so you couldn't Strike then Grapple with a Forceful weapon and gain the damage from Forceful on your Grapple.

Otherwise, yes, all of these interactions work.

Attack rolls do not specifically mention "miss" either ;-)
