Staff usage clarification - two separate tradition spell lists.

[Midgefly]

So the rules for using a staff state:
"You can Cast a Spell from a staff only if you have that spell on your spell list, are able to cast spells of the appropriate level, and expend a number of charges from the staff equal to the spell’s level." (page 592)

My question lies with this particular scenario:

I am a level 10 Sorcerer with the Elemental Bloodline, I have just picked up the feat Bard Dedication http://2e.aonprd.com/Feats.aspx?ID=677.

As a sorcerer with the Primal Tradition I am able to cast spells from this list up to level 5 spells.

With bard dedication, I am able to cast Occult cantrips and gain access to the Occult spell list.

If I equip a Staff of Divination http://2e.aonprd.com/Equipment.aspx?ID=353, am I allowed to cast "True Stike", a level 1 spell from the Occult spell list?

Breaking down the staff rules:

1. You can Cast a Spell from a staff only if you have that spell on your spell list.
-Yes I have access to the Occult spell list.
2. are able to cast spells of the appropriate level
-Yes, but they are Primal spells up to level 5.
3. and expend a number of charges from the staff equal to the spell’s level.
-I would be able to add 5 charges to the staff being a level 10 Sorcerer.

So with these points being satisfied, am I able to cast True Strike from the staff? Or must my "are able to cast spells of the appropriate level" come from a spell's particular tradition?

You need to be able to cast the spell from an ACTUAL spell slot that you ACTUALLY posses.

You cannot, or perhaps maybe should not, be able to game the system via discrete reading. The intent is clear here, you need to 1) Have the Spell on a list you can cast & 2) Have a Spell Slot that you're able to use to actually cast said spell.

Just my 2cp.

Sigh, another one of those badly written rules that invites people to attempt an exploit...

The intent here is clearly that you "are able to cast spells of the appropriate level FROM THAT LIST". I'd rule it to say that.
