With its low AP requirement of 17, a player with high Agility can deliver a good deal of damage with only a single round of V.A.T.S. By combining Luck, Finesse and the Ninja perk in various ways, Stabhappy will critical strike 100% of the time. The weapon also damages limbs at a slightly increased rate.
The raiders inside and outside the shack (including the one which carries the Stabhappy) respawn every 72 hours, allowing the player an unlimited supply of Stabhappy's. This is not so much a bug, but more of an re-spawning flag oversight by a programmer. The game functions properly, though possibly not as the programmer intended. 表达式错误：未预料的<操作符Template:Navbox weapons FO3
