Telescopic Sight

The Telescopic Sight is a item in Risk of Rain that gives the player a 1% chance to instantly kill an enemy. Its proc is signaled by a reticule appearing around the soon to be dead enemy, and a loud gunshot that sounds similar to the Sniper's ability.

Trivia
The text "Spinning while firing is also a great way to lose your license" is a reference to the trend of "360 No-scoping" kills done in the Call Of Duty series especially, where the player would use a Sniper Rifle, spin 360 Degrees and fire without looking down the scope, supposedly showing a large amount of skill and good reaction times when done accurately.
