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

Leading Fire. When the courser misses a creature with a ranged weapon attack roll by 5 or less, they may move the target to a free space within 5 feet of the target's current location.

Lethal. When the courser scores a critical hit, it doubles its ability bonus to the damage roll (already included). Furthermore, any time the courser attacks a living creature and rolls the maximum possible result on at least one of the attack's damage dice, that creature takes an additional 4 (1d8) damage.

Legendary Resistance (3/long rest). If the courser fails a saving throw, it can choose to succeed instead.

Night Vision Scope. The courser gains darkvision out to 210 feet while carrying their institute laser in their hands. Due to the limited field of vision and the scope’s magnification, the courser cannot use this darkvision to help them explore; it is of benefit only during combat and for sighting distant objects and creatures while in the dark.

Actions

Multiattack. The courser makes three attacks. If the courser makes ranged weapon attack rolls against two or more targets during the same turn and hits at least two targets, it can deal an additional 2 (1d4) damage to one of those targets.

Detect. The courser makes a Wisdom (Perception) check.

Attack. The courser makes an attack.

Throw. The courser makes a martial arts attack. On a hit, the target must also succeed at a DC 19 Dexterity saving throw or be knocked prone in any space of the courser's choice within its reach. If there is already a creature in the chosen space, it must move to make room and if it can't move, the courser can't choose that space.

Charge. The courser moves its speed then makes a melee attack.

Fade. The courser moves up to half its speed then makes a Dexterity (Stealth) check if it is out of sight of all hostile creatures by the end of the movement.
