Treasure Goblins are known for that “Tee hee” giggle sound they make, but a new legendary drop would be a necklace with the above name that allows a player to walk through mobs unmolested as long as they 1. Do not have any followers/pets active and 2. Do not attack the mob. Could even put it on a cool down timer or something so it’s not horrible OP.
Well, the entire game is about killing stuff so I see no situation where this would be desirable… Also there is already a boot item that allows unhindered movement. Since basically all mobs are set to aggro on the hero on sight, making something to change that behavior would be very difficult I imagine.
Also I don’t see people going through the trouble to unequip their pet to make use of this either. Likewise with the follower as desummoning that would eliminate a huge number of emanate effects.
