Merge:
Added vortex to Orion's spears.

General:
Changed packfile type back to mod because I forgot after finishing debugging phase.

Fixes:
Percentage-based WoM cost reduction for Lore of Vampires now affects upgraded spells as intended.

Balance:
Lore of Vampires cost reduction effects all reduced to either 10 or 15%.

Content:
Removed Arkhan's extra bonuses to VMP units.
Rescaled Arkhan's existing bonuses to VMP units.
Added a third rank to Arkhan's VMP unit buff skill that adds melee defense to all VMP units.

Fixes:
Arkhan's WoM cost reduction for Lore of Vampires reduced from 30% to 20% due to issues arising therefrom.

Fixes:
Noticed incorrect magic weapon source for Arkhan. Replaced with a standard effect.

"Balance":
Flaming attacks are now outright a detriment to combat effectiveness without sources of fire weakness. Arkhan no longer enables flaming attacks via army capstone. Instead, magical attacks are enabled at rank 3. Mannfred can get fucked, though.
Arkhan's army capstone now (lazily, proper changes will occur Soon™) provides bonuses to Arkhan's special vampire menagerie.

Fixes:
Corrected minor issue with TZE skill tree that arose from not checking key orders while copy/pasting.

Balance:
Reduced effectiveness of CHD WoM cost reduction effects by half. Drazhoath ought to no longer have to worry about all spell costs being reduced to 0, as an added bonus.

Fixes:
Finished work on two Tzeentch character skill trees.
Added missing combat skills to Nurgle-aligned sorcerer lords, and Tzeentch-aligned sorcerers/sorcerer lords.
Fixed several post-battle movement effects.

General:
TWA10 compatibility update (two dozen mount entity and a few animation ID's changed).
Added some of the TWA10 buffs to BRT characters.

Fixes:
Enabled Zhatan's melee weapons...
