"Applies 2 stacks of damage over time effects instead of 1."
Location
The blueprint for the Alchemic Carbine is located in a secret area of the Ancient Sewers, above a big pool of poisonous water.[1] It is very likely to fall and get stuck in the poisonous water, therefore it is not advised to enter this room while cursed.[a] The secret area will keep spawning until the blueprint is claimed.
Synergies
Despite its low damage, Hokuto's Bow can drastically increase its effectiveness by adding the damage bonus to every poison tick.
Due to its inherent ability to inflict poison, it can works well with Sadist's Stiletto, HemorrhageRotG and Snake FangsFF, all of which inflict critical hits on poisoned enemies. Furthermore, it can be reliably triggered since it does not have any ammunition and can be used to the player's desire.
It can also be paired with Acrobatipack if the player does not want to use the Carbine for practical combat.
Poison from this weapon can be used to trigger the Toxin Lover aspect.
Notes
Affixes such as "+60% damage on a bleeding target" apply to the projectile damage as well as the inflicted poison status but not the resulting poison cloud.
Trivia
This item was previously named Alchemic Gun and Alchemic Rifle, although both are inaccurate as it resembles a small crossbow.
