It's just a shame that the official mod tools are so neutered in the name of Wizards being able to protect their brand. No custom asset support, no map editor, no cutscene editor, no new NPCs or dialog, etc.
Basically, you are limited to making new gear (but limited to gear models that already exist), tweaking spell effects, and custom dice skins apparently.
One can hope, but some features like a level editor may be too much to bet on.
At the very least, the official mod tools don't seem like they'll be adding anything that modders haven't already figured out how to do themselves, so we're no worse off than we were.
Yeah, it's a bit of a let-down when you compare what's on offer here with a previous Larian title like Divinity 2. That game lets you make full on campaigns.
