Perfectionist's Brew Trait Clarification

[Besengo]

Perfectionist's Brew
You know that potion recipes should be followed with exact precision.

Benefits: You gain a +2 trait bonus on all Craft (alchemy) checks and on Spellcraft checks made to brew potions.

Hello mates, I'm not sure about this trait. How am I supposed to treat it?
Is it a flat +2 on alchemy AND a +2 on spellcraft to make potions

OR

is it a +2 on (alchemy and spellcraft) to make potions?

The "all" before craft alchemy confuses me.

Sorry if you consider it a silly question, to me it's not
Thank you anyway :)

[QuidEst]

The first. All alchemy, specific spellcraft. The "all" and the repeated "on" are what clarify it.

Thanks for your reply, QuidEst. (Is there a like function or smth?)
I'll wait some more answers, though.

To read like the second interpretation the second use of "on" in the sentence would be omitted.

Quote:

Benefits: You gain a +2 trait bonus on (all Craft (alchemy) checks) and on (Spellcraft checks made to brew potions).

In this sentence, the word "on" is signals a new grouping. So the effect is a flat +2 on all Craft(alchemy) checks AND +2 on Spellcraft for potions.

Thanks for your reply, KingOfAnything. You made the exact same grammatical considerations that I made on another facebook forum. But on fb people keep telling me that my grammar is incorrect.

I think I'll wait one or two more opinions, then I'll consider this issue solved.

Just in case: I'm not English mother tongue, so I could be missing some subtle meaning in the trait description.
Are you a native English speaker?
And what about QuidEst?

[KingOfAnything]

I am a native English speaker.

There are only two words in the sentence that change the meaning between your first and second interpretation. I can understand why some people on Facebook might be reading this one incorrectly.

I read it as the trait gives you +2 to all craft alchemy. It also gives you a +2 to spellcraft checks specifically to make potions.

[Cavall]

You use Alchemy to create alchemical items and to identify potions (As an alchemist).

Spell craft is for crafting magic items.

Because it's saying you gain it to ALL on one thing AND on something thing else, I'm reading it as others are.

I can see why others would argue as its a little against the concept of potion making as its written and it's slightly more powerful than other traits on average.

But the wording is clear.
