I have officially concluded my modding journey on this workshop.
As always: feel free to make any kind of submods for any of my mods.

@flyons_gary You need to assign the specific unit code to specific faction codes in their respective tables through either PFM or RPFM.
For custom battles you need to change stuff in the units_custom_battle_permissions_tables while for campaign you'll need to change stuff in the units_to_groupings_military_permissions_tables.
If you are new to modding I suggest you to read some guides before attempting to make changes, It's quite easy to mess things up if you don't know what are you doing.

Out of curiosity how would one mod the unit so it could be used by other factions?

UPDATE PLZ! LOL J/K....Great mod. Norsca needs all the help it can get...I am surprised no one has added frost hydra's to them tbh...Hydra's started out as a chaos monster waaaaay back when, before they were handed over to DEs. If your ever bored and have the time, give it some thought :)

Just noticed this is a norscan unit.

Nevertheless I stand by what I said.

More LizardCHADmen units are never enough.

They look BA
