Sneak.
Hide.
Camo.
Creep (race dependant).

And when someone successfully camos, no one that can't see camo can see them. If we made this equivalent to magic, everyone would get an "awareness" check, and have the chance to see the camo'd person, despite camo having been used successfully.

Why should every skill operate identically? Why should sleep, strange, choke, stun, blackjack, spinebreak etc all have the same method of operation?
