Prestige class question with spellwarp sniper

[LaRayna]

Hey everyone, there's a prestige class that I'm looking for that I feel pairs with the sniper, but I can't remember the name. I believe it's a three level prestige class that can advance the class features of a previous class taken.

Shadowbane Stalker? Level 4 loses a caster level.

Uncanny Trickster. You might also be interested in Legacy Champion, which can do the same thing for more levels.

[Paragon]

Uncanny Trickster.

I second that.
