Class Features

All of the following are class features of the Trapsmith.

Weapon and Armor Proficiency: A Trapsmith is proficient with whatever they were already proficient with.

Booby TrapsEx: You can quickly set up simple booby traps (see the sidebar) to harm and hinder your foes. When setting up a trap, make a Craft (trapmaking) check. The check result is the Difficulty Class of an attempt to find the trap by making a Search check. Half the check result is the DC of an attempt to disarm the trap by making a Disable Device check. The check result affects other variables, too; see below for details. Setting up a booby trap is usually a full-round action, though some take longer.

Starting at 3rd level, your skill improves such that you can create advanced versions of the simple booby traps you already know.

Master DisarmerEx: Your skill at finding and disarming traps is legendary. When dealing with a trap, add your trapsmith level to your Search checks, Disable Device checks, and Open Lock checks.

TrapfindingEx: You are adept at evading the effects of traps, gaining bonuses at 1st level, 3rd level, and 5th level. See the barbarian class feature. Trap sense gained from other sources (such as barbarian or rogue levels) stacks with this benefit.

Spells: If you are smart enough, you might gain the ability to cast arcane spells. To cast a particular spell, you must have an Intelligence score of at least 10 + the spell’s level. Your bonus spells are based on your Intelligence. Saves to avoid the effects of your spells have a DC of 10 + Caster Level. You cast spells as a bard does. The spells per level table below, details how many spells you can learn at each level. Choose your spells from the following list.

1st—arcane sight, cat’s grace, clairaudience/clairvoyance, dispel magic, fox’s cunning, gaseous form, haste, knock, protection from energy.

2nd—arcane eye, dimension door, lesser globe of invulnerability, Otiluke’s resilient sphere, stoneskin, stone shape.

3rd—Bigby’s interposing hand, break enchantment, fabricate, greater dispel magic, wall of stone

Arrow ProofSu: When a trap activates, you know how to lessen the impact and reduce the damage. Starting at 2nd level, you gain damage reduction 5/— against the effects of traps. The reduction applies only to damage from physical attacks, such as arrows, crushing blocks, or pits. Damage caused by spells or magical effects is not reduced. Damage reduction gained from multiple sources stacks, but only for damage dealt by a trap.

Quick FingersEx: Starting at 2nd level, you can disarm traps more quickly. When you attempt a Disable Device check, use the table below in place of the standard table for disarming traps. If you have the quick fingers alternative class feature, reduce the time needed for checks on difficult and wicked traps to 1d3 rounds.

UnweaveSu: At 3rd level, your understanding of magic traps allows you to unweave their magic, as if targeting the trap with dispel magic. Your caster level for this ability equals 5 + your trapsmith level. You can use this ability three times per day. It works only against magic traps, but spells such as alarm, glyph of warding, and the symbol spells are valid targets.

Dance Through DangerEx: Starting at 4th level, when you make a Search check to find a trap and your result exceeds the DC by 5 or more, you can move past the trap without setting it off. This benefit applies only to you—the careful movements and balance needed cannot be taught to your fellow adventurers.

Spell-proofSu: Starting at 4th level, you enjoy a measure of protection against magic traps. You gain spell resistance equal to 15 + your trapsmith level. This spell resistance applies only to magic traps, which include spells such as fire trap, explosive runes, glyph of warding, and the symbol spells.

Avoid DisasterSu: At 5th level, you learn to negate the effects of a trap as they happen. Once per day, when a trap is sprung, you can make a Disable Device check as an immediate action. If the check succeeds, you quickly disable the trap and avoid its effects. If the check fails, the trap activates as normal.
