In case you missed it on the Discord channel there is a fix I saved from the OLD OLD Styss that turns the scooting ruby statues into mobile ruby golems. These are AKA the "Blood Elemental Berserkers".
The folder pathway to follow is :
Computer > Users > (your user here) > My Documents > Neverwinter Nights > Override
Place all three files into the Override folder, and start NWN: EE.
I just tested this myself right now on TRI, and it works.
Please post any issues you may have with the files. Thank you.
