Boltcasters are made up of two parts, a Damage Core and a Base. Boltcaster Damage Cores are interchangeable, and most can use any core.

All Boltcasters are ranged weapons, with the Ammunition (with a range set by Base), Blast, and Recharge (with the number of charges set by Damage Core, and the charges used per attack set by Base), and deal damage set by the Base with a damage type set by the Core.

Boltcasters are not simple or martial weapons and no class starts with proficiency in Boltcaster. They must take the feat "Bolt Slinger" to get it.

Blast. Ammunition used by a blast weapon is destroyed upon use and cannot be recovered.

Recharge. Recharge weapons have a number of charges set in the property. Each time you attack with the weapon, you reduce the number of charges by the number of charges used per attack, which is also set in the property. If this would put the number of charges into the negative, the weapon cannot be used. A Recharge weapon with zero charges has an inert core and cannot be used. The core can be replaced as an action.

Tiered. Some Boltcasters are designed for use with only a specific tier of Damage Core, set in the property. They cannot use any tier of Core except the one set in the property
