Okay Fixes:
Doubled Checked Ethereal Shard Gauntlet(ESG), everything looks good on my end so hopefully people stop having various issues with it xD
Fixed Frost Purifiers XCOM Row

Changes:
Added Elerium Cores as requirements for a lot of the advent secondaries (1 Core for Magnetic Version, 2 Core for Beam) - Wanted to add more cost to upgrading them but not inflate corpe requirements, should at least require thinking about building them early on till you have a bunch of cores (as you will be using cores on these instead of other things)
Moved all Advent Melee upgrades to Muton/Muton Elite (other then ESG)
ESG moved to plated/powered armour to be equivalent to templar gauntlet
Moved Magnetic Launcher to regular magnetic weapons (it being on mecs was me forgetting to change it from frost gremlins template as i was making it)
Removed Void Rift from T3 Priest/Raptor Amps (seeing as its no longer on T3 amps) as it ended up just being damage if the unit didnt have insanity/other stuff (at least i never saw them use insanity on enemies after using it while not having it)
Nerfed Frost Purifier base armour by 1
Nerfed Bio Barrier Trooper base hp to 6

Added:
Support for Underbarrels and Bayonets for MOST advent primary weapon (exceptions: Destroyer Assault Rifle/Raptor Sniper Rifle, they got some internal issues/might need some tweaking to work properlly): Note some of them might be pretty ugly in the way they are attached, it requires a lot of micro adjusting, then launching the game back/forth, will be something i address over time/improve

Fix for Wraith Commandos not getting more focus with weapon upgrades

Fix for Wraith Commandos Ballistic tier Gauntlets paired weapon being craftable

Localization Update for Weapons/Armours

Bugfix for Restored and Beam Ethereal Shard Gauntlets

Bugfix for Pathfinder Hunters XCOM Row

Added Purifier to the list for Advent Armour so you can build it properly if you only have a purifier

Set up Requirements/Alt Requirements for Frost Legion Armour and Bio Trooper Armours so they wont show up unless you have one of the proper units

Nerfed Bio Barrier Troopers Armour by 1

Replaced Marked For Death on Raptor Commando with a custom Marked For Death (Same Name) that will actually work with the Raptor Commandos Vektor Rifle

Requires Pet Rock Perk Pack Update

Gatecrasher Advent now spawn with gear: Plating, Medikit, Frag Grenade

unfortunately no compatibility with randomised gatecrasher loadout yet so they will always have these items

Raptor Commando: Replaced MarkedForDeath with XCOMHunterMark_LW which is the correct ability and should not have localization problem

Fixed Traversal rules for Deployable Frost Droids and Frost Mecs
Fixed Localization for Deployable Frost Droids SMG
Fixed Localization for Deployable Frost Mecs Cannon and Launcher

Removed Interact_TakeVial and Interact_StasisTube from ALL Advent character templates to avoid crashes/soft locks, please remember to bring at least 1 Human to Blacksite/Forge

Fixed Bio Barrier Trooper having Double Time Twice, Lightfoot to SGT

Added Config to allow Bio Barrier Troopers with Guard to get a stack of Guard if they dont attack

All 18 active Advent have had their XCOM Rows Tedified at 5/5/5/5/6/7 perks in the xcom rows at each rank

Major balance pass on 17/18 of the Advent: Note Priest rework will be a 1.1 thing once I learn particle effects for psi abilities

Bunch of small fixes/tweaks/localization

Fixed up Frost Technicians frost mec that had some funny T pose shenanigans

IsModActive code implemented which should allow this mod to be run without the individual enemy packs and you SHOULD only get advent for the enemy packs you have active, Will need feedback if there are any issues/advent showing up that shouldnt if you have one of the mods disabled

priest can use their mind control now while having someone holy warriored
