I'm sure quite a few already know this, but I just discovered this as of late when trying to fix some issues with my WoG installation. Tried to tweak things to no avail.

Then I found out that his gem exists. Cannot believe I never knew it.
It's compatible with SoD

Adds so many good features and is still being worked on. Compatible with HotA as well.

For those who already knew it - please help praise this mod :D

For those who are new to it - download and enjoy!
