[X] To stop the ritual: primary goal, stop whatever fuckery the khornates are doing.
-[x] to start with, buff all the undead with whatever spells and sorcery the necromancers can conjure
-[x] Giants are to throw whatever chunks of rock they can at the walls AND within the city-scape in hopes to disrupt whatever the hell is going on inside, such rituals are...finicky and even the slightest disruption can cause it to go aray.
-[x] However have a few giants aim to at the gates and walls at key points, zombie tides are to swarm the as fast and hard as possible, skeleton warriors provide over watch with a walking constant barrage of arrows (fire by rank's)
-[x] once the walls are breached or if enough of a ramp is made, the gravegaurd are to open up the breaches in order to allow the black knights to charge forth to wherever the ritual is being taken place. We are on a time limit here, and ensure every kill made does not bleed as much as they can. Also during the attack raise any dead that they come across to use as fodder against the daemons.
-[x] Necromancers that still remain are to try and contest the ritual, or at least force the khornates to do MORE work in order to summon whatever greater daemon they are trying to utilize, all the while the rest of them strategically banish and/or curse the enemy forces to allow maximum damage against the enemy.
-[x] once the walls are breach and the gatehouses secure, giants are to "Carefully" provide heavy artillery to whatever positions are needed to either crush or demolish pathways to the ritual site.
--[x] On the way, free any slaves and ensure that as few sacrifices get to the ritual site as much as possible to prevent any warp summoning. ---[x] If ritual site is secure, taint it towards Dracul or siphon the power away as "conquest" against the horrors of the warp (if at all possible and the necromancers think its worthwhile, this is a bonus objective)
[x] Focused Attack: Concentrate your forces then launch them at focused attacks directed at the front walls, augment undead, focus magical attacks on focused attack points.
