Skeletons and Ghouls unlocking similar to Pyro/Cryo/Reaver

[Hedrachi]

Maybe for other undead races have a cemetery area, completely optional like ruins are, has two "subdungeons" (or more if more undead races are planned to be unlockable), say a "Broken Catacombs" for wights and a "Defiled Chapel" for vampires? Go in each, go down to bottommost level, kill the boss and you unlock the race. Should be very hard but still doable.

[Burb Lulls]

Related to the Master idea, what if beating the Master x times with a warrior class unlocks ghouls, x times with an archer class unlocks skeletons, rogues for wights and mages for vampires when they're implemented?

[Repton]

A couple more ideas to toss out:

1.
(a) Unlock skeletons when you kill the Shade.
(b) Unlock skeletons when you are killed by the Shade. (this is how I unlocked them anyway )

2. Unlock ghouls when you have suffered a certain amount of blight damage.

[Final Master]

I've gotten both pyro/cryo mancers unlocked with a random generated archmage. I knew I was getting close, but I unlocked both with the same character (well... two, I just recreated it, it was one then the next). Once I get some play time in with both, I'll have a good review of them, along with what the tempest class should kind of be like.
