Oathkeeper
Oathkeeper + Soldier = Warlord
Oathkeeper + Demolitionist = Archon
Oathkeeper + Nightblade = Dervish
Oathkeeper + Arcanist = Paladin
Oathkeeper + Occultist = Sentinel
Oathkeeper + Shaman = Shieldbreaker
Oathkeeper + Inquisitor = Opressor
Oathkeeper + Necromancer = Templar
Or same but
Oathkeeper + Arcanist = Templar
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Necromancer = Opressor
Attempt #3:
Oathkeeper + Soldier = Warlord
Oathkeeper + Demolitionist = Archon
Oathkeeper + Nightblade = Shieldbreaker
Oathkeeper + Arcanist = Oppressor
Oathkeeper + Occultist = Sentinel
Oathkeeper + Shaman = Templar
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Necromancer = Dervish
No, because that’s not how a guessing game works. As there’s a prize involved until someone gets it right (or Zantai has to give away so many other class names it’s impossible not to get it right :eek:) you’ll just have to wait. 
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Dervish
Oathkeeper + Inquisitor = Sentinel
Oathkeeper + Shaman = Shieldbreaker
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Oppressor
Oathkeeper + Necromancer = Archon
Oathkeeper + Demolitionist = Paladin
Been Lurking for a long time but for fun, speculative reasons I’ve gotta have a guess. Ironically I don’t even want the free copy but I can’t help myself.
Oathkeeper
Shieldbreaker - Soldier + Oathkeeper (going against the grain. The name makes me think of Spartans charging in using the shield for offense and defense)
Warlord - Demolitionist + Oathkeeper (A warlord makes me think of burning down villages and in the modern world also blowing them up)
Paladin - Inquisitor + Oathkeeper (The inquisitor already has auras and seeks to hunt down evil so it seems a good fit to me)
Oppressor - Occultist + Oathkeeper
Sentinel - Shaman + Oathkeeper ( A sentinel makes me think of a silent guardian or watcher and the Shaman fits there)
Templar - Arcanist + Oathbreaker (I see a Templar being slightly more cerebral and elemental based than a Paladin)
Dervish - Nightblade + Oathkeeper
Archon - Necromancer + Oathkeepr
I do sort of hope Warlord is the Necromancer as it’s my favorite class and my nickname is always Warlord so it would work for me 
It’s also the class that would command a small army easiest.
and one more because I’m not 100% sure
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Dervish
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Shaman = Sentinel
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Oppressor
Oathkeeper + Necromancer = Archon
Oathkeeper + Demolitionist = Shieldbreaker
Zantai has already said that Warlord is Oathkeeper and Soldier. Try again.
(I cant stop, please help)
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Dervish
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Shaman = Shieldbreaker
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Sentinel
Oathkeeper + Necromancer = Archon
Oathkeeper + Demolitionist = Oppressor
Well I’ll definitely be playing a Soldier + Oatherkeeper then
Guess #2 before I go back to playing Grim Dawn and trying not to get too hyped about Forgotten Gods (more than I already am)
Oathkeeper
Warlord - Soldier + Oathkeeper
Shieldbreaker - Demolitionist + Oathkeeper
Paladin - Inquisitor + Oathkeeper
Oppressor - Occultist + Oathkeeper
Sentinel - Shaman + Oathkeeper
Templar - Arcanist + Oathbreaker
Dervish - Nightblade + Oathkeeper
Archon - Necromancer + Oathkeepr
Place the fresh, still warm from the printer, receipts for 5 copies of Grim Dawn at the 5 points of a large inscribed pentagram on the floor and start chanting “Iatnaz”, “Iantnaz” “Iantaz” “I beg the Forgotten Gods for help!” 
Edit…Bonus points for smoking, dribbly candles, wearing a long black hooded robe and including all the expansions in the receipts
Another try:
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Oppressor
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Shaman = Dervish
Oathkeeper + Arcanist = Shieldbreaker
Oathkeeper + Occultist = Sentinel
Oathkeeper + Necromancer = Templar
Oathkeeper + Demolitionist = Archon
Guess #3, this time with some wacky/dumb/maybe logical ideas:
Soldier + Oathkeeper = Warlord
Nightblade + Oathkeeper = Dervish
Demolitionist + Oathkeeper = Shieldbreaker
Occultist + Oathkeeper = Sentinel
Arcanist + Oathkeeper = Templar
Shaman + Oathkeeper = Archon
Inquisitor + Oathkeeper = Paladin
Necromancer + Oathkeeper = Oppressor
Edit: Note to self, don’t make guesses when I’m barely awake.
Gonna have a number #3 cause now as I’m slowly hyping myself 
Oathkeeper
Warlord - Soldier + Oathkeeper
ShieldBreaker - Nightblade + Oathkeeper
Archon - Demolitionist + Oathkeeper
Paladin - Inquisitor + Oathkeeper
Dervish - Shaman + Oathkeeper
Sentinel - Necromancer + Oathkeeper
Oppressor - Occultist + Oathkeeper
Templar - Arcanist + Oathkeeper
And then I’ll probably have a guess everytime I have a break now cause I can’t help myself
I’m also thinking that maybe Lorewise for Grim Dawn it might also be :-
Oppressor - Inquisitor + Oathkeeper
Paladin - Occultist + Oathkeeper
As the Oathkeeper’s do worship the Witch Gods
Oathkeeper + Soldier = Warlord
Oathkeeper + Demolitionist = Archon
Oathkeeper + Nightblade = Shieldbreaker
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Sentinel
Oathkeeper + Shaman = Dervish
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Necromancer = Oppressor
Soldier - Oathbreaker = Warlord
Shaman - Oathbreaker = Dervish
Necromancer - Oathbreaker = Oppressor
Demolitionist - Oathbreaker = Paladin
Nightblade - Oathbreaker = Sentinel
Inquisitor - Oathbreaker = Archon
Arcanist - Oathbreaker = Shieldbreaker
Occultist - Oathbreaker = Templar
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Dervish
Oathkeeper + Inquisitor = Paladin
Oathkeeper + Shaman = Shieldbreaker
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Sentinel
Oathkeeper + Necromancer = Oppressor
Oathkeeper + Demolitionist = Archon
Second attempt.
This has been difficult - I would have expected someone to have guessed correctly by now. Some of our assumptions are clearly incorrect.
I find that Archon, Dervish and Shieldbreaker are the most difficult to logically assign. I picked Shieldbreaker for Shaman purely because of Horvald Shieldbreaker, a lightning-based hero.
second guess
Archon = Oathkeeper + Arcanist
Dervish = Oathkeeper + Nightblade
Oppressor = Oathkeeper + Occultist
Paladin = Oathkeeper + Inquisitor
Sentinel = Oathkeeper + Shaman
Shieldbreaker = Oathkeeper + Demolitionist
Templar = Oathkeeper + Necromancer
Warlord = Oathkeeper + Soldier
Third guess:
Soldier -> Warlord
Nightblade -> Sentinel
Demolitionist -> Archon
Occultist -> Dervish
Inquisitor -> Paladin
Arcanist -> Templar
Shaman -> Shieldbreaker
Necromancer -> Oppressor
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Shieldbreaker
Oathkeeper + Inquisitor = Sentinel
Oathkeeper + Shaman = Dervish
Oathkeeper + Arcanist = Templar
Oathkeeper + Occultist = Oppressor
Oathkeeper + Necromancer = Archon
Oathkeeper + Demolitionist = Paladin
Oathkeeper + Soldier = Warlord
Oathkeeper + Nightblade = Paladin
Oathkeeper + Inquisitor = Opressor
Oathkeeper + Occultist = Sentinel
Oathkeeper + Arcanist = Archon
Oathkeeper + Necromancer = Templar
Oathkeeper + Shaman = Dervish
Oathkeeper + Demolitionist = Shieldbreaker
