Firearm Modifications

If you do end up being a fan of the Legendary Games stuff please go support them at https://www.makeyourgamelegendary.com/ because they are great and deserve all the love we can send their way.

Due to  their  complex  design,  firearms  are  able  to  be  modified  in  a  number  of  ways,  each  helping  to  further  customize  one’s  weapon. Unlike normal  weapon  modifications,  firearm  modifications  do  not  cost  extra  to  add  to  a  magical  weapon,  and  up  to  two  different  modifications  can  be  applied  to  the  same  firearm. As long  as  a  character  is  proficient  with  a  firearm,  they  are  proficient  with  any  modified  version  of  that  firearm. Each firearm  modification  comes  with a Craft DC, requiring a Craft (firearms) check which takes 1 hour to  add  this  modification  to  a  weapon. A firearm  modification  can  be  removed  with  a  DC  10  Craft  (firearms)  which  takes  10  minutes,  ruining the parts used for that modification but leaving the firearm intact. Some firearm modifications can also be applied to crossbows; these follow  the  same  rules  as  applying  them  to  a  firearm  as  well  as  other  exceptions  to  the  rules  listed  previously,  although  a  Craft  (crossbows) check is needed in place of a Craft (firearms) check.

Improved Firing Mechanism
Cost +5,000 gp; Craft DC 20

A firearm with an improved firing mechanism reduces its misfire rate by 1 (minimum 0).

Improved Rifling
Cost +10,000 gp; Craft DC 30

A firearm with improved rifling can target a creature’s touch AC in its second range increment.

Improved Sight
Cost +5,000 gp; Craft DC 20

A firearm with an improved sight gains a +20 foot circumstance bonus to its range increment.This firearm modification can also be applied to crossbows.

Integrated Weapon
Cost +2,000 gp (plus the cost of the weapon); Craft DC 20

A firearm  with  an  integrated  weapon  combines  itself  with  a  melee  weapon,  serving  as  both  a  firearm  and  the  weapon  integrated  into it. A creature is treated as wielding both the firearm and the integrated weapon while wielding a firearm with this modification, and both weapons share the same enhancements (enhancements that can only be used by one weapon can be applied to this firearm, but cannot be used if they would not normally be a valid choice for that weapon type, such as a vorpal pistol). A one-handed firearm can only  be  integrated  with  a  light  weapon,  while  a  two-handed  weapon  can  only  be  integrated  with  a  one-handed  weapon. Integrated weapons can be made masterwork for 300 gp, making both the  melee  weapon  and  firearm  masterwork. Removing this  firearm  modification  destroys  the  melee  weapon  and  if  the  integrated weapon had an enhancement which would only apply to a melee weapon (such as vorpal), that enhancement is lost.This firearm modification cannot be applied to axe muskets, buckler guns, fire lances, pistol daggers, sword cane pistols, or warhammer muskets  (as  well  as  additional  weapons  as  decided  by  the  GM),  and  double  weapons  cannot  be  integrated  with  this  firearm  modification.This     firearm     modification can also be applied to  a  crossbow,  treating  a  hand  crossbow  as  a  one-handed  firearm,  and  other  crossbows  as  two-handed  firearms  for  the  purpose  of  which weapons can be integrated into them.

Simplified Loading Mechanism
Cost +5,000 gp; Craft DC 20

A firearm  with  a  simplified  loading  mechanism  reduces  the  action  needed to load a firearm as long as it would be able to be loaded as a full action or quicker; from a full round to a standard, standard to move, and move to free action.This firearm modification can also be applied to crossbows.SHORT BARREL Cost +7,500 gp; Craft DC 25A firearm with a short barrel increases its spread’s area by 5 feet.This firearm modification can only be applied to firearms which have a spread option, such as dragon pistols and blunderbusses.

Silencer
Cost +3,000 gp; Craft DC 20

A firearm with a silencer does not produce any noise when fired.

Weighted Grip
Cost +2,000 gp (+5,000 for two-handed firearms; Craft DC 15 (25 for two-handed firearms)

A one-handed firearm with a weighted grip is treated as a light weapon for the purpose of two-weapon fighting.

A two-handed firearm with a weighted grip is treated as a one-handed firearm for the purpose of how much effort it takes to wield.This firearm modification can also be applied to crossbows except for hand crossbows; a crossbow can be treated as either a one-handed firearm or  a  two-handed  firearm  when  determining  the  benefit  gained from it, chosen at the time the modification is applied.
