Stonecunning. Senani is considered proficient in History when making such a check to reveal information about stonecraft or masonry, and adds twice her proficiency bonus to the check, instead of her normal proficiency bonus.

Dwarven Resilience. Senani has advantage on saving throws against poison.

Assassinate. During her first turn, Senani has advantage on attack rolls against any creature that hasn't taken a turn. Any hit Senani scores against a surprised creature is a critical hit.

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

Sneak Attack. Once per turn, Senani deals an extra 25 (7d6) damage when she hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of Senani that isn't incapacitated and Senani doesn't have disadvantage on the attack roll.

Reliable Talent. Senani can’t roll lower than a 10 on the die when rolling an ability check she’s proficient with.

Blindsense. While Senani can hear, she can sense the location of any creature that is hidden or invisible within 10 feet of her.

Shadow Touched. Senani can cast the [Tooltip Not Found] and disguise self spells each once. After she does, she can’t cast that spell again until she finishes a long rest.

Impostor. After spending at least three hours studying another person’s speech, writing, and behavior, Senani can unerringly mimic those mannerisms, giving her a +10 bonus to any check made to pass herself off as that person.

Mobile. When Senani takes the Dash action on her turn, difficult terrain doesn’t cost her extra movement on that turn. Additionally, when Senani makes a melee attack against a creature, that creature can’t take opportunity attacks against Senani for the rest of that turn.

Legendary Resistance (1/Day). When Senani fails a saving throw, she can choose to succeed instead.

Special Equipment. Senani has and is attuned to a ring of mind shielding, a ring of protection, a set of mithral half-plate, and a breath-stealing sword. She also keeps a [Tooltip Not Found] for difficult situations she finds herself unable to fight or escape from without using it.

Multiattack. Senani makes two attacks with her Breath-Stealing Sword. She can make a third attack with a light hammer if she’s wielding one.

Breath-Stealing Sword. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 6) slashing damage, or 12 (1d10 + 6) damage if wielded with two hands, and the target must make a DC 15 Constitution saving throw. On a failed save, the target is stunned until the end of its next turn.

Light Hammer. Ranged Weapon Attack: +8 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 7 (1d6 + 3) bludgeoning damage, and the target must make a DC 16 Strength saving throw, falling prone on a failed save.

Cunning Action. Senani takes the Dash, Disengage, or [/action]Hide[/action] action.

Uncanny Parry. In response to being hit by an attack, Senani increases her AC by 5 for that attack, potentially turning a hit into a miss. If the attack hits, its damage is halved.

Senani can take 1 legendary action, choosing from the options below. This legendary action can only be taken at the end of another creature's turn. Senani regains the spent legendary action at the start of her turn.

Roll. Senani moves up to half of her speed without triggering opportunity attacks and takes the Hide action if she is behind cover or is heavily obscured.

Kneecap. Senani makes an attack with a light hammer she’s holding.
