Update:

Completely reworked all corruption effects because goddammit CA.

Fixes:
Morathi's chaos corruption penalty changed from faction_to_region_own to faction_to_province_own_factionwide.
Made the same change to Malus' penalty for becoming a full-fledged daemon. Both skills used together should be significantly more manageable for Untainted-prefering dork elf factions now, especially with the Quintex landmark.

Balance:
Slightly reduced chaos corruption at max level of Morathi and Malus' corruption-adding skills.
Malus' exorcism capstone path now provides faction-preferred corruption. This may be reverted to untainted in the future if this proves too easy for Morathi.

Balance:
Brought Daemon's Curse and Reaper of Souls a bit more into line with Impactful Magic's version of them.
Reaper of Souls' per tick HP drain reduced considerably, but occurs every tick now.
Uptime for both skills considerably increased.

Text:
Added another layer of localization for the non-vanilla possession effects. The first layer sometimes didn't work for some reason.

Balance:

Reduced Tz'Arkan ability's overall HP drain and increased healing from Reaper of Souls. Reaper of Souls damage decreased, but effect area increased and the effect can target 2 models per affected unit.

Added:
A capstone skill dilemma for Malus has been added. The player has the choice of going the canonical route of exorcising the daemon from Malus (for army bonuses) or the also somehow canonical route of having Tz'Arkan devour Malus' soul and manifest properly (for various campaign bonuses). See known issues. Subject to change Soon™.
Snikch and Repanse have their respective capstone skills now.
Melee tweaks for all 3 new LL's completed.

Balance:
The skaven shared campaign capstone (Tretch, Queek, and Snickers) has had its research bonus adjusted at rank three.
A small number of army skills have been made factionwide at rank 3 with reduced strength.

Compatibility:
Mod now uses a data__ version of campaign_group_member_criteria_numeric_ranges and is incompatible with anything that messes with the thresholds for faction resources (skaven food, chivalry, fightiness, loyalty etc.)

Fixes:
Queek did not have the shared campaign capstone skill for some reason.
Fixed several skill icon picture typos (probably didn't matter).

Known issues:
Malus' possession guage will never go below -8 without drinking a potion. Threshold for full control was changed due to this. The gauge in the UI will not reflect Malus being fully in control.

It is still possible to drink potions for temporary control and it is still possible to use the possession button every 40 turns. Both of these can potentially fuck up Malus' possession effects.

Do not press these buttons until I can either rework this from the ground up or get a script to remove the possession UI when one of the skills is acquired.

Balance:
Added custom shields from Firepower.
All legendary characters use appropriate shield values now.
Some resistance values tweaked.
