This mod will scale up NPCs and enemies to your current level (it does NOT scale down).
Enemy names will be recolored depending on difficulty:
Easy - Green
Normal - Yellow
Hardcore - Orange (+2 to all attributes)
Very Difficult - Red (+4 to all attributes)
This event is triggered by the perception event, so, if an enemy does not perceive you, it might not scale up.
(perception in terms of mechanics should happen before the stealth check, so even stealthed you can still be perceived).
Warning: this may not be always balanced.
INSTALLATION: extract the contents of the zip file in your My Documents/Neverwinter Nights 2/Override/ folder.
