About a decade or so.
Yes, he needs to die once for the plot to be available.
No, halfbreeds do not exist in warhammer, stop trying to spawn monstrosities.
They do exist in Wh40k though? Not trying to be offensive
I was playing as Malekith (whom I immediately turn to Chaos Undivided, using cheats. Don't judge me, its just jarring how the Dark Elves worship flawed and false imitations of the Dark Gods) and started interbreeding his dynasty with that of humans and dwarves.
Trying to go for genetic traits and it turns out that A LOT of Chaos Dwarfs have good ones!
-Shouldn't important characters such as Malekith and the Phoenix King have a greater chance of becoming Everchosen? (I know, breaking the 'canon' of the game. But it would be cool to play as Malekith the EVERCHOSEN King!!!)
-Malekith died when attempting to summon a daemon without a prisoner. FIRST ATTEMPT!!!
-Malekith should have a decision to legalized Male Sorcerers
-Aren't a good portion of Dark Elf Nobility DIRECTLY descended from Malekith himself!?! I think that his fertility score be upped because he DOES have children and descendants!
I did another playthrough as Chaos Kislev (yeah, I'm a Chaos fanboy!) AND LOVED buying guns and armor from the Chaos Dwarves!
-Kislev and other Kislevite/Ungol nations (while not under the influence of the Dark Gods) should receive Chaos Adventurer invasions Decades after the start of the game. (They can have the choice of letting the guys go and invade the empire (if the Chaos dudes want to attack the Empire) or fight them)
-Kislevite nations should have extra fortifications (or let it be an option in the late game)
-Daemonic Invasions. Both Naggaroth and the Kislevite nations should be under attack by Daemons late game
Anyway love the mod! Hopefully Ruler Designer would be made compatible in a next patch!
