Strategies for Rezo battle

[Pazvante]

In my currently impossible Soothsayer game the undead army in the tower is made up of:

• 22 Bone Dragons
• 8843 + 8844 = 17687 Skeleton Archers
• 397 + 103 = 500 Necromancers
• 680 + 33 = 713 Cursed Ghosts
• 373 Ghosts
• 604 Vampires

The leadership of one of the skeleton archers stack is around 123K.

I'm level 45 and have about 15K leadership.

I'm slowly cleaning up "new" Arlania but soon I'll have to tackle the army above and it does not look easy
