So, I'm currently in the process of creating some elite advances (that work kinda like those in the previous games. For those that don't know what I'm talking about, it's basically a separate advancement table, which you can gain access to if you fulfill certain requirements, and pay some xp. It also often came with unique talents and abilities) for my players, but I went kinda overboard with it (as in, there is no way all of them are getting used). So if any of you are interested, I can post them here (but I want to see if enough people are actually interested before I do it, because these include quite a few house rules, and I would convert them back before posting). My sources of inspiration are varied, but I always tried to stick to the fluff (at least, my version of it). So here are those I have already done:
Warsmith
Raptor
Berzerker
Dark Magos
Psy-Lord
Champion of the Black Legion
Son of Alpharius
Son of Omegon
Warmaster
Reaver Lord
Infiltrator
Death Dancer
Oracle
Shroud Warrior
Herald of the Gods
Arcanist
Talonmaster
Chaos Lord
Glory Hound
Reaver
Exarchial Guard
Heretek Stalker
Pyroclast
Apostate Paragon
Archeretek
Cryomancer
Phantom
Alpha Psyker
Skull Champion
Planned (those are just ideas at the top of my head, so I'm not sure any of them will be actually done):
Plague Lord
Exalted Champion
Crimson Lord
Gal Vorbak
Night Haunter
Voidlord
Dark Genetor
Soul Hunter
Warp Assassin
Warlord
Apostate Cardinal
Gore Mage
Orator
Malefic Scholar
So, anyone interested?
