During the Flavors of Mayhem quest, Rose requires the player character to shoot the syringer at an enemy, with the intention that the player character hide during the 60 seconds that the enemy is temporary buffed, and then easily killing the enemy while it is weakened during the subsequent 60 second period. This weapon will not work on robots; use it only enemies that are "flesh and blood."
However, this weapon is equally effective with other teammates to give them a temporary buff for 1 minute, with the understanding that during the subsequent minute they will temporarily become more vulnerable to enemy attacks.
Karma syringe details
+25 DR, ER and RR for 30 seconds
+15% damage for 30 seconds
+50 max hp for 30 seconds
Does not work on Essential NPCs, SBQ, Wendigo Colossus or any Robot/Turret
If the mod is applied to another syringer (not Rose's Syringer) Rose will not recognize the mod and the quest can not be advanced. While the incorrect Syringer can be scrapped, scrapping the modified item does not recover the karma mod
The buff effect only lasts 30 seconds and there is no debuff period after it wears off.
