Jack (weapon)

Jack is equal in power to the Ripper but has a higher critical rate.

Location
Jack can be found inside the Deathclaw Sanctuary on an Enclave Officer. The officer spawns alive, but unless you cleared out the deathclaws on an earlier visit, she won't be by the time you reach her. Refer to the map for the general area, but remember, since she and the other officers spawn alive, there's no telling what you'll find.

Obviously, this weapon is not available until The Waters of Life is completed.

Characteristics

 * The higher critical chance increases the power of this weapon enormously because it hits over 30 times per second. The listed weapon damage is divided over the individual hits, but the critical bonus damage is not.  This means every hit has a normal chance to critical and do the full critical bonus damage.  With Better Criticals and Ninja this is quite possibly the strongest melee weapon in the game in real-time combat.
 * This weapon does an additional 50% limb damage. Due to the extra limb damage, it will cripple nearly any limb hit on contact. This can make fights against NPC's and Super Mutants very easy, due to them not attacking you because they are too busy grabbing the body part that has been crippled.
 * Sneak attack criticals are devastating with this weapon, especially while in VATS.
 * This weapon is higly effective against Deathclaws and typically kills within 3-7 seconds depending on where you hit them with it.

Trivia

 * This weapon's name is likely a reference to Jack the Ripper, one of the most infamous serial killers in history.

Bugs
Holstering Jack (and probably a regular Ripper, but that remains untested by this author) while you are using the Chinese Stealth Armor or a Stealth Boy and sneaking will cause it to disappear mid-animation. It's minor, but interesting.
