Bugs

 * The bonus to the actual sneak attack damage multiplier on silenced weapons provided by this perk is known to behave erratically when interacting with Cloak & Dagger and Mister Sandman. Patch 1.4 tried to address this bug, so that you could no longer reach a 6.3x multiplier. However, there was still some variance depending on the order you obtain the three perks. The current multipliers are:
 * Sandman 3, Ninja 3, Cloak = 4.4x
 * Ninja 3, Sandman 3, Cloak = 4.7x
 * Sandman 3, Cloak, Ninja 3 = 4.7x
 * Ninja 3, Cloak, Sandman 3 = 4.8x
 * Cloak, Ninja 3, Sandman 3 = 4.8x
 * Cloak, Sandman 3, Ninja 3 = 4.8x
 * Right now the only solution for and  appears to be selecting/receiving these perks in the "correct" order. The reason these differences happen is because, although Cloak & Dagger and Mister Sandman both use multiplication, Ninja is set to use addition. Because order of operations matters when both are mixed, results from having all three perks can vary.


 * The Ninja perk works very oddly with melee attacks. One-handed weapons are always treated as melee, and unarmed are always treated as ranged attacks. Rank one doesn't affect two-handed melee weapons at all, rank two treats two-handed weapons as ranged weapons, and rank 3 finally treats two-handed melee weapons as melee weapons. This results in a very bizarre sneak attack damage progression for two-handed melee weapon users, and a very low one for unarmed users.
