Sabotage Artist

Starting at 3rd level, your expertise with tools, mechanisms, and traps grants you a unique set of skills that make you a master saboteur and scout. You gain proficiency with Tinker's Tools. You can use Tinker's Tools in place of thieves' tools when disarming traps.

Additionally, you have advantage on Wisdom (Perception) and Intelligence (Investigation) checks made to detect the presence of traps and hidden doors.

Finally, you can use your trap save DC for determining the DC of ball bearings, caltrops, nets, and hunting traps. You can use ball bearings or caltrops in place of an attack.

Sapper Magic

You learn the mending cantrip if you don’t already know it.

You also learn an additional spell of 1st level or higher when you reach certain levels in this class, as shown in the Sapper Spells table. Each spell counts as a ranger spell for you, but it doesn’t count against the number of ranger spells you know.

Trapper's Craft

Starting at 3rd level, you have learned to create various traps to alert you from danger and to hinder or destroy your enemies. 

Schematics. You start knowing three schematics from the "Schematic Options" section below. You learn one additional schematic when you reach certain ranger levels, at 7th, 11th, and 15th level. Whenever you gain a level in this class, you can replace one of the schematics you know with a new one. A level prerequisite refers to your level in this class.

Creating Traps. When you finish a long rest, by using your Tinker's Tools, you can create a number of traps equal to your proficiency bonus using schematics you know. You can have a maximum number of traps equal to your proficiency bonus. If you create a new trap while you have your maximum number of traps, the first one you have created is immediately destroyed. Each trap created this way must use a different schematic, limiting you to 1 trap of each kind. A trap you create is a tiny object with an AC of 18 and a number of hit points equal to 6 + twice your Ranger level. It is immune to poison damage and psychic damage, and all conditions. If the mending spell is cast on it, it regains 2d6 hit points. It is destroyed if it is reduced to 0 hit points. Unused traps are destroyed when you finish a long rest.

Using Traps. As an action, you can arm and deploy one of your traps on an unoccupied space within 5 feet of you, or you can disarm and retrieve one of your deployed traps within 5 feet of you. A deployed trap is hidden from sight, but a creature can use its action to make a Intelligence (Investigation) check against your Trap DC to find one of your trap’s locations. You and any number of creatures you designate when you deploy a trap always know it's location while it is deployed. All trap schematics have a Trigger Condition and an Effect. Once the Trigger Condition of a trap is met, the trap's Effect immediately takes place, unless otherwise stated. If you or a designated creature would trigger one or more of your traps, you can choose to have the trap not trigger instead. Once a trap has been triggered, its location is revealed and the trap is destroyed.

Saving Throws. Some of your traps require your target to make a saving throw to resist its effects. The saving throw DC is calculated as follows:

Trap save DC = 8 + your proficiency bonus + your Wisdom modifier

*Your DM may create custom schematics or allow you to design new schematics for your Sapper Ranger. Talk with your DM about these possibilities.

Trap Schematics

Below are the trap schematics available to the Sapper Ranger.

Acid Trap

Trigger Condition: A creature comes within 5 feet of the trap.

Effect: Each creature within the 10 feet of trap must succeed on a Dexterity saving throw or be covered in acid for 1 minute or until they or another creature uses its action to scrape or wash the acid off itself or another creature. A creature covered in acid takes 2d4 acid damage at the start of each of its turns.

Bear Trap

Trigger Condition: A creature enters the trap's space.

Effect: The creature must succeed on a Dexterity saving throw or take 1d6 piercing damage. If the creature is large or smaller, that creature is grappled as well.

On a success, a creature or object suffers none of the trap's effects.

Neurotoxin Trap

Effect: A potent neurotoxin spews from the trap.

Sapper's Strike

Starting at 7th level, when you use your action to arm and deploy one of your traps, you can make one weapon attack as a bonus action.

Remote Trigger

Also at 7th level, you can, as a bonus action, trigger any of your deployed traps within 120 feet of you, whether it meets its trigger condition or not.

Trapshot

At 11th level, you have mastered the art of combining your marksmanship with your trapping skills. When you take the Attack action, you can forego one of your attacks and attach one of your unused traps to an arrow, crossbow bolt, or thrown weapon, creating a Trapped Weapon. A Trapped Weapon has a maximum range of 60 feet, regardless of the weapon’s normal range.

On a successful hit with a Trapped Weapon, the target suffers the standard effects of the attack. Additionally, the trap is triggered, with its effects emanating from the creature's space. The target has disadvantage on any saving throw made against the trap's effects.

If the Trapped Weapon attack misses, the trap is destroyed upon impact without triggering its effects.

Snare Savant

Starting at 15th level, when you roll initiative and aren't surprised, if you have no traps remaining, you can craft one trap using one of your known schematics as part of rolling initiative.

Additionally, you have advantage on saving throws made against your traps. If one of your traps would subject you to a saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
