Yvresse Invasions

What this mod solves:
When playing the Tor Yvresse campaign, I always felt the Greenskin threat from Grom always felt distant - especially on the Vortex campaign. This mod solves that by adding Greenskin invasions as you level up the defences of Tor Yvresse.

ME or Vortex?
This mod impacts both campaigns, however to respect the sandbox nature of ME - the invasions are likely to remain a minor aspect. For the Vortex though, I intend to fine tune the mod so that the present threat of Grom continues to escalate right up until that final battle.

Doomstack spawning sucks though?
Yup - but this uses the system introduced in Twisted & Twilight DLC. Markers are placed and can take between 1 to 3 turns before a full army stack is spawned. If you send an army to the marker before then, you can ambush a weaker force and stop the spawn.

How does it work?

• On both Vortex and Mortal Empires, as the defence level of Tor Yvresse hits its key three thresholds markers will be placed along Ulthuans south eastern shores. These will spawn full armies for the Broken Axe faction (Grom). These armies will seek to attack Tor Yvresse itself.
  
• These army strength varies with each invasion but will always be 20 stacks.
  
• On the Vortex campaign, completing the three Greenskin outpost quests will reduce the strength of the invading armies.
  
• Attacking the markers before the army musters will result in an ambush against a 10 stack army.

Mod Configuration Tool
This mod now supports the MCT to allow you to tweak how string you want the invasions to be!

• You can set the base level strength for each of the three invasions (max level 10).
  
• You can set how much weaker the strength level of an army is if you intercept it.
  
• You can set how much weaker invasion armies get for completing the greenskin camp missions.

Default values:
Invasion 1 strength: 4
Invasion 2 strength: 6
Invasion 3 strength: 10
interception modifier: 2
Mission completion modifier: 1 (per mission, total of 3)

Possible future Features:

• Script Optimisation: It works fine - but it's a but clumsy and not scalable.
  
• More invasion thresholds for Vortex campaign.
  
• Have varying size armies on marker interaction depending on how early you intercept them.
