Edit it with Notepad or Notepad ++ variant. See post above for area to modify, for example: new entry "HardcoreNPC" section
Save it here: You will need to create a few sub directories ..\Divinity Original Sin 2\Data\Public\Shared\Stats\Generated\Data
Start the game, there will be a warning about a modified version, run it and you can see the changes in Vitality for example using before/after.
Q: What does this do and what should i edit?
A: The goal is to adjust the stat boost NPC's get in Tactician mode.
Q: That file in the game directory? Or do i copy this file you posted and paste it into the appropriate directory?
A: Yes copy that. Go to your game directory, however as you drill down the sub folders will no longer exist, add those in as shown here. ..\Divinity Original Sin 2\Data\Public\Shared\Stats\Generated\Data
Once copied in here, edit the file.
Q: I should edit only the "hardcoreNPC"? What do i edit to lower their hp bloat and armor bloat?
A: Yes. You can edit what you like, but the topic is NPC hp/armor bloat etc.
Q: ok then, so
HARD:
new entry "HardcorePlayer" type "Character"
new entry "HardcoreNPC" type "Character" data "ArmorBoost" "0" data "MagicArmorBoost" "0" data "Vitality" "0" data "DamageBoost" "0" data "Accuracy" "0"
hows this?
Or do i just delete those last five entries alltogether?
A: You can do either, set to 0 or remove the line.
I also suggest you go into HardcorePlayer and add: data "Vitality" "100"
Check your Vitality before, then do this whole step above, run the game and check vitality after, it should be noticeably higher. This is to make sure this mod has kicked and you done it right. Then when it is working, exit, remove the Players Vitality 100 and play the game with adjusted NPC stats.
This is all based on if Tactician mode is more than just stat boosts. I don't think that has been clearly answered. If is it just a stat boost, play another difficulty level then.
Q to RAZE: Are you able to confirm Tactician mode is just stat boosts or is their additional AI behaviors, mob formations, etc? Thanks.
