While this is a PvP addition, The idea in of itself is relatively simple. As buildable quality goes from wood to bricks to metal, consider this the metal rarity of specialised optics. The thermal scope is to be considered a Scorpion 7 spawn. To keep it balanced, it will only provide an 8x magnification. However, it has a very useful feature. You will be able to see the thermal emissions of animals and other players. However, there are a few drawbacks. Firstly, the rarity will make finding the scope very difficult. (ITSSS BALLANCED BECAAAUSSE ITSSSZZ RAAER!!1!1) Secondly, the scope will not work if the target is behind any form of buildable/object. If the head, body and whole left side of your character is behind a tree, the right arm and leg will still be visible. Thirdly, The thermal imaging scope will still be able to magnify and show thermal readings beyond its range, but these will be far more faint than closer readings. Finally, I'm not sure how you would be able to pull it off but this will be a sniper/marksman rifle weapon attachment only. I see this being very useful on a map like Yukon, when nightvision does provide some form of visibility in the snow, albeit limited visibility.
