How are attribute points used for a special class?

[DoUrden]

I just leveled my Conjurer to level 31 and working on Arcanist to be able to become a WhiteMage.
With bonus points for the CNJ put them all in to Mind.
For Arcanist, I looks like those should go in to Int.
But when I get in to being a WhiteMage does that combine those points, and if so should consider keeping them all in Mind for both the CNJ and the Arcanist?

The Arcanist points will only ever be used for Summoner and Scholar, never your WHM. Only CNJ points affect WHM.

If you just plan on doing ACN for your WHM soulstone, you can put them into INT. If you want to try out Scholar after WHM though, you can go ahead and put them into MND.
Don't worry, you are able to change them with the item "The Keeper's Hymn" available at a GC for seals, if you really want to respec the stats.

The points are tied to the class. (And any jobs associated with the class)

For example, if you put 30 points into MND for Conjurer, you will have 30 points in MND as White Mage.

For Arcanist, if you put 30 points into INT, you will have 30 points in INT for Summoner, and 30 points in INT as a Scholar as well. (Due to this, you might want to carry around some reset stones (Keeper's Hymn) if you plan on playing Summoner and Scholar. You can get them from your Grand Company for 250 seals each)
