Shockingly (given how long this game has been out) I have been unable to find a single decent QRS for LOTR SBG. For my Charge of the Mumaks game I had to do one up as without a good one the rules are spread all over the place which really grinds down the pace of the game. This only gets worse with more "powerful" characters in the game. The QRS really helps keep things on track and for new players explains much of the abilities of the characters they have in their force.
You can download the QRS from here (also in the downloads section to the right).
UPDATED 2/20/2018 - now includes additions covering magical powers, weapons and wargear.
I don't have the special rules or casting magical spells covered yet, but I will add that in a future revision. Images below of the pages.
