There are some differences in language between certain combination weapon traits that I'm having trouble with.
The sweep trait uses one form of language:
"When you attack with this weapon, you gain a +1 circumstance bonus to your attack roll if you already attempted to attack a different target this turn using this weapon."
The forceful trait, another:
"This weapon becomes more dangerous as you build momentum. 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 the kickback trait, yet another:
"A kickback weapon deals 1 additional damage with all attacks."
My gut says that none of these traits should apply outside of the mode in which the trait exists. The RAW language, though, makes me think there's more nuance to it. Sweep, especially, feels like it should apply regardless of mode: it's still the same weapon, even if only one mode bears the sweep trait. Forceful seems like it should apply, but it doesn't have the same "this weapon" word usage. Kickback seems to disagree with both, implying that the kickback damage only applies when the weapon is in ranged mode - it's only a kickback weapon if it can kick.
I haven't been able to find anything in the forums addressing this issue so far. Am I missing something? Is there a good RAW way to rule this?
