Editing Isabella von Carstein (section)

==On The Tabletop==
Isabella is part of the infamous Vlad/Isabella combo where if one dies, the survivor becomes more powerful (unlike their fluff). Said survivor tends to be Vlad after Isabella is used as a sacrificial lamb due to his superior killyness and resurrection powers, once again breaking lore.

The problem with Isabella by herself was being essentially a weak Hero level Vampire with no important upgrades. Her only benefit was a magic item chalice allowing her to let another vampire in her unit drink from it and restore a Wound. She paid too much for an iffy power, and thus was in no way worth using unless the plan was to buff Vlad with her death.
With the End Times 50% character allowance this strategy is more viable (ironically).
If one wishes to use a "V+I 4ever "army, using Isabella's model (as a generic Vampire Lord) in an Undead Legion list with Mortarch Vlad is the only viable way.
A proper von Carstein list of the era should use Corpse Carts as Vlad and Isabella were the first to use them, Black Coaches as they are the mainstay of Sylvanian vampires, and Vargheists/Varghulfs as the von Carsteins created them by locking naughty vampires in tombs until they went feral from thirst. Be sure to include some Empire troops proxying things to represent the loyal living humans of Sylvania.

End Times Archaon brings her back as a confusing mix of her old self with some new tools for the Daemons of Chaos and Grand Legion of the Everchosen armies. Chief among them is now being a Level 3 Wizard with Lore of Vampires & Nurgle, which is a curious mix. She keeps her Undead and Vampiric rules, but also gains Hatred (Undead), which works as well since any undead she wounded have to take d3 additional unsavable wounds and everything in base contact with her during the Magic Phase takes an S1 hit that ignores armor. Her chalice was also changed, becoming essentially a grenade that forces anyone that was hit by it to test Toughness or die. The issue with this is that despite being tougher, she's now more vulnerable since she can only recover a wound through the Lore of Vampires trait (And three of the spells, one of which is the SIGNATURE SPELL, involved will likely be useless unless you also get Raise Dead). HOWEVER, on her own she is absolutely awful, as she lacks the daemonic instability rule, so she cannot join units of daemons, which is her HOME ARMY.
