The Draenor expansion’s absolute best thing is Findle’s Loot-a-rang. Did you kill something that’s surrounded by things you can’t or don’t want to kill? Send the loot-a-rang in to fetch the goodies. Did something you kill end up halfway down the hill with no way to loot it? Yup, you get your loot.
Hands down, without question, this little device made by engineers is a true treasure, worth the slot it takes up in your bag. Not only will it loot everything within killing range, it is usable by level 1 players.
