Why Arcane Trickster?
Choosing a Gnome for your Arcane Trickster Rogue creates a brilliant utility character who excels at stealth, illusion, and trickery. While standard Rogues rely purely on physical agility, your high Intelligence allows you to cast spells that confuse and distract your enemies. This makes you the ultimate toolkit for your party, solving problems with magic rather than brute force.
Your Gnome heritage grants you Darkvision, which is essential for scouting ahead in pitch-black dungeons without alerting guards with a bright torch. Additionally, Gnomish Cunning provides advantage on mental saving throws against magic, making you incredibly resilient against enemy spellcasters while you sneak behind enemy lines.
At level 3, you unlock Mage Hand Legerdemain, upgrading the standard spectral hand so you can pick locks, disarm traps, or pickpocket from a safe distance while remaining completely hidden. This synergy of innate gnomish resilience and magical thievery makes you an elusive shadow on the battlefield.
Arcane Trickster Features
Spellcasting
Level 3You learn wizard cantrips and spells from the enchantment and illusion schools. You use Intelligence as your spellcasting ability. You know three cantrips: Mage Hand and two other wizard cantrips of your choice. You also learn three 1st-level wizard spells, two of which must be from the enchantment or illusion schools.
Mage Hand Legerdemain
Level 3When you cast Mage Hand, you can make the spectral hand invisible. You can also perform additional tasks with it: stow or retrieve objects from containers, pick locks, or disarm traps at range. You can do these tasks without being noticed by making a Dexterity (Sleight of Hand) check contested by the creature's Wisdom (Perception) check.
Magical Ambush
Level 9If you are hidden from a creature when you cast a spell on it, the creature has disadvantage on any saving throw it makes against the spell during that turn.
Versatile Trickster
Level 13As a bonus action, you can direct your Mage Hand to distract a creature within 5 feet of it. You have advantage on attack rolls against that creature until the end of your turn.
Spell Thief
Level 17When a creature casts a spell targeting you or including you in its area of effect, you can use your reaction to force the creature to make a saving throw with its spellcasting ability modifier. On a failure, you negate the spell's effect against you and steal the spell if it is between 1st and 4th level. For the next 8 hours, you know the spell and can cast it using your spell slots. The creature can't cast the stolen spell until 8 hours have passed. Once you use this feature, you can't use it again until you finish a long rest.
