Tools Proficiency. The arcane trickster is proficient with the following tools, adding the following additionnal bonus to skill checks made when using them : Thieves' Tools (+10).

Sneak Attack (1/Turn). When the arcane trickster hits a creature with an attack and has Advantage on the attack roll, or an ally of the arcane trickster without the Incapacitated condition is within 5 feet of the target while the arcane trickster didn't have Disadvantage on the attack, that attack deals an extra 35 (10d6) Piercing damage (included in the attack).

Evasion. If the arcane trickster is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the arcane trickster instead takes no damage if it succeeds on the save and only half damage if it fails.
