Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Any easiest way to test own mod?

Hello. I'm a new who've started modding myself, especially for balancing and revisions of skills, race abilities, and so on.

I have a question for the modding; Is there any easiest way to test my own mod?

For example, suppose I've created a simple mod that reduces AP cost from a skill, and want to check whether it is correctly applied or not. Do I really need to turn off the Engine Tool and turn on the D:OS2 every single time for the checking?... Or, is it possible to test the modding result on the Tool itself? Like in-game checking.

Thanks in advance!
