Unchained Multiclassing

[rlfhog3]

I've got two questions regarding the unchained variant on multiclassing that maybe you guys can help me out with.

When using the Variant Multiclassing system does one gain anything beyond the secondary class features of the secondary class?
For instance, say i was a fighter with his secondary class being Wizard. Would all I gain be what is listed on the table for the wizard or do i also gain access to spells like a wizard does?
How about vice versa. If i was a wizard with a secondary class of fighter would i gain any of the weapon proficiencies that fighters normally do or otherwise?

Secondly,
How do you guys think the system works in conjunction with things like prestige classes? Suppose i end up qualifying for a prestige class and i'm using the Variant Multiclass system already. Let's say I'm a cleric with the wizard subclass and i decided i want to prestige into Agent of the Grave. How should i go about doing that in this system?

You only get the features listed in the Variant Multiclassing section. Nothing else. So if a fighter chooses the VMC Wizard class he doesn't get spells (except the cantrip mentioned in that section), and a Wizard doesn't get the fighter weapon proficiencies. You also don't count as having levels in your VMC class for purposes of qualifying for feats.

The idea behind VMC was that you would pick it in place of normal multiclassing. So no Prestige Classes. However, it is from Unchained, so experimentation is sort of the theme. So a lot of people mix the two together. I'm really not very familiar with divine casting classes, so I'm afraid I can't help you there.
