Ninja

Ninja is a Fallout 3 and Fallout: New Vegas perk.

Effects
The Ninja perk grants you the power of the fabled shadow warriors. When attacking, you gain a +15% critical chance on all Melee and Unarmed attacks. Additionally, Sneak attack criticals do 25% more damage than normal. This perk is more suitable for players who follow a "ninja" play style, similarly to Grim Reaper's Sprint, which is suitable for players who follow play styles that use V.A.T.S. more often.

Bugs

 * In Fallout: New Vegas Ninja multiplies your critical chance by 1.15 instead of adding a flat 15%, unlike all other perks/traits that modify critical chance. For example, a character with a critical hit chance of even 25% would have it be increased to only 28.5% rather than to 40% as it should. (25% * 1.15 = 28.75% vs 25% + 15% = 40%)
 * In Fallout 3, the extra 15% critical bonus does not work without the help of the unofficial Fallout 3 patch.
