Fixed an issue with the script.

Numerous tweaks and fixes.
The initial starting horde will now begin with the Chaos Cult Chain again! (Thanks to sm0kin!)
Fixed Missing Huskarl Shields.

Updated with various tweaks and fixes.

The Archaon Update:

New custom Portrait and icon!
New flaming Chaos effects.

Archeon's skillsets have been further re-done!
Now instead of the Lore of Fire Archaon has the Lore of the Everchosen, a custom lore set involving powers and blessings from all four chaos gods.

New Skill: Mark of the Everchosen, Grants bonuses from each god and access to the Pink fire of Tzeentch Spell.
New Skill line: Lore of the Everchosen, special Archaon versions of the chaos spells giving him all three passive boosts from the chaos spell deck along with a Khorne boon unique to Archaon.
Lore of the Everchosen also grants Archaon access to Call to Glory, Aura of Acquiescence. Miasma of Pestilence, Slicing Shards of Slaanesh & the Flame Storm spell. These versions are different from the sorcerer versions as they cannot be upgraded as Archaon is not a dedicated caster.

As the Mark of the Everchosen makes Archaon unbreakable his "Indomitable" skill has been replaced with the custom "Rending blows" skill.

Since Archaon's other special skills and his battle line were already updated in the update yesterday along with his starting traits this all adds up to make Archaon a significantly different character!
Enjoy!

UPDATE:

Created a new set of battle skills that tie in better with the orginal chaos units and the new UC units.

Sorry about that.

Updated For Vampire Coast DLC!
The mod should run correctly now with Vampire Coast.

MISC:
Updated Loadscreen Text - If you want more quotes warhammer related suggest a few!

CA have removed some effects and effect scopes form the database with the latest patch.
Therefore some skills have had to be re-worked and I havent had tome to fully test them all.

Notably:
There is a tech that adds recruitment points - can someone verify it still works correctly.
Horde Growth boost techs.
Plague Doctor Campaign skill that effects Horde replenishment rate.

I ahve tested it along with the invasion script but there may be some other glitches here an dthere due to the size and scope of the mod, please report these if any arise with as many details as possible.
