This adds the generic tunic you see on some priests as a camp clothing option. Ideal for a humble Cleric, Paladin or any other ascetic character.
Also included are the Open Hand Temple Ilmater robe and some new other god options added piecemeal.
As of v5 this mod is compatible with Wine and Revelry Satyr Race.

Notes
- I gave the generic tunic new, nicer textures than the original. This does not affect the version you see on NPCs.

- The amulet will look strange standalone as it's designed to fit on a specific mesh, it will float off the chest oddly or clip depending on what outfit you wear.

- Although the Ilmater tunic can be equipped by all races, its cord bracelet and amulet only appear on the regular size humanlike female, regular size humanlike male, dwarf male and halfling female, as meshes only exist for those races in the files. The amulet should appear on strong races as of v4 however.
Other races and bodies have the open hand logo on the back as I made new mesh code entries for them.

How to Install
Recommended that you install with BG3 Mod Manager. A guide to BG3MM installation of mods can be found here. Mod fixer may be required.

You can find the box containing the clothes in the tutorial chest or sold by the Druid Trader. You can use a mod like this or this or this to access the tutorial chest if you are past this area.

If you want to spawn it manually the box mapkey UUID is a8a65bf7-72b2-40c2-a1fb-14be3f38c16c

To uninstall the mod, you need to resummon the tutorial chest, drop all the items and bags back in it, let the chest disappear, and save. Or use Trashcan. However, I do not recommend uninstalling any mods that add items mid playthrough, and I cannot help you if you run into difficulties because of this.

Other Mods You May Like
Any dye mod with pantheon colours can make it match your character's god better, I use Faerun colors.
There is an Ilmater dye in Vestments of the Faithful.
If you want more shoe options, I recommend Camp Boots.
