Amulet of shawdows too OP

[Golken]

Quick facts:
-This isn't particularly relevant to the OpenMW project. Was kinda surprised to see this thread here, but maybe it fits.
-Yes, this item is grossly unbalanced as well as very accessible and easy to get.
-The powerful Chameleon effect itself is too common (in good magnitudes) and easy to amass in the vanilla game.
-The game's vanilla content is conclusively littered with imbalances in general. Its difficulty is also too low. There are a bunch of mods that rework this, each in their own flavor. As a starter, one can look into Wakim's Game Improvements and BTB's Game Improvements, and search for balance mods to find more.
