Unsupported for the time being until I get back into BG3. I'll leave it open for everyone who found it helpful for now.

~*~

Without BG3SE, this list is moot. Kvalir has written a great article on how to activate the console. REMEMBER to save before using commands, just to be on the save side.

~ Item List ~

The list in the file section currently includes the following items: Armour and clothing, head-, arm and footwear, rings and amulets, weapons. I'm still working on adding arrows, camp clothing, alchemy ingredients and camp supplies.
The list is a simple .txt file. Just unpack it somewhere and open it with Notepad or a similar app.

~ Console Commands ~

1. Add Item to Inventory:
TemplateAddTo("UUID", GetHostCharacter(), quantity)

Example adding one Selunite Robe to your inventory:
TemplateAddTo("204de787-46de-4d39-8fe0-2e080bf44a61", GetHostCharacter(), 1)

Huge txt file with item UUIDs is in the files section. Still wip though.

2. Add Gold:
AddGold(GetHostCharacter(), X)
Change X to the desired amount of gold you would like to add

3. Add Experience
Osi.AddExplorationExperience(GetHostCharacter(), X)
Change X to the amount of xp you need. You need to do this for each toon in the party.

4. Set Tadpole State
SetTadpoleTreeState(GetHostCharacter(), X)

Replace X with the state you want to achieve:
1: Hesitant to use worm powers
2: Ready to use worm powers

5. Add Tadpoles
AddTadpole(GetHostCharacter(), X)

Replace X with the amount of parasites you want.

6. Add Inspiration Points
Osi.GiveInspirationPoints(GetHostCharacter(), X, "", "")

Replace X with the amount of Inspiration Points.

7. Change Appearance
Osi.StartChangeAppearance(GetHostCharacter())

I don't know what happens if you're on an origin character and don't have the Appearance Enhanced mod. Might cause issues, so make sure to save before using it.

8. Respec
Osi.StartRespec(GetHostCharacter())

9. Change Approval
Osi.ChangeApprovalRating("COMPANION UUID", GetHostCharacter(), 0, X)

Change COMPANION UUID with the ID from below. Don't accidentally remove the quotation marks.
Change X to the amount you want to add. You can also remove approval by putting a minus before the number.
