Schematics

You learn five schematics of your choice, which are detailed below. Many schematics enhance an attack in some way. You can use only one schematic per attack.

You learn two additional schematics of your choice at 7th, 10th, and 15th level. Each time you learn a new schematic, or when you level, you can also replace one schematic you know with a different one.

The schematics below include plans for trick shots, grenades, chemical weapons, and RMPPL customizations.

Pinned. On a hit, target must make an Athletics or Acrobatics Check against your Spell Save DC. A failed check results in movement 0 and disadvantage on attacks until end of your next turn.

Shocked. On a hit, the target takes an additional 1d8 lightning damage and can’t take reactions until end of your next turn.

Scorpion. The projectile remains connected to the RMPPL when fired. On a hit, the target must make a Strength Saving Throw against your Spell Save DC or take 1d8 piercing and be pulled 15’ towards you. The projectile releases after target is moved.

Improvise!. You can take a non-mundane substance and convert it into a warhead on the bolt. This changes the damage type from piercing to something related to the substance.

Concussion. All creatures within 10’ radius of impact point must make a Constitution Saving Throw against your Spell Save DC or take 2d6 bludgeoning damage (½ on a save) and knocked prone.

Bubbly Toes. A sticky and bubbly foam expands to fill a 10’ radius area of difficult terrain from the impact point that lasts 1 minute. All creatures who start their turn within the area must make a Strength Saving Throw against your Spell Save DC or have speed reduced to zero. Creatures who have failed can repeat their saving throw at the start of their turn.

Spiders. Mechanical spiders pour out of the impact area, filling a 10’ radius. Any creature starting their turn must make a Wisdom Saving Throw against your Spell Save DC or have disadvantage on attacks until end of your next turn.

RMPPL - Flamethrower. 1/LR, RMPPL expels a 15’ cone of fire. All creatures within range must make a Dexterity Save against your Spell Save DC taking 2d8 fire or half on a successful save.

RMPPL - Big Bada Boom. 1/LR, RMPPL overwinds and fires the projectile with extreme force. On a successful hit, target takes an additional 2d12 bludgeoning damage.
