Sunlight Sensitivity. While in sunlight, the kobold has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Pack Tactics. The kobold has advantage on an attack roll against a creature if at least one of the kobold's allies is within 5 feet of the creature and the ally isn't incapacitated.

Dagger. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.

Sling. Ranged Weapon Attack: +4 to hit, range 30/120 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage.

Sticks to Snakes (1/Day).  The Stonechanter tosses a handful of sticks through the air and enchants them with conjuration magic, temporarily turning them into poisonous snakes.  Choose one creature within a range of 30 feet, or choose two creatures within range that are also within 5 feet of each other.  A target takes 1 piercing damage and must succeed on a DC 11 Constitution Save or take 3 (1d6) poison damage and be poisoned until the end of their next turn.  The snakes turn back into sticks after their bite attack.

Stone Bombardment (Recharge 5-6).  The Stonechanter throws a handful of enchanted stones into the air, landing in a 5 foot radius with a range of 30 feet.  All creatures in the area of effect must pass a DC 11 Dexterity Save or take 4 (1d6+1) force damage.  If there is only one creature in the area of effect, then that creature takes an additional point of force damage, even if they pass the Dexterity Save.

Enchant Stones (at will).  The Stonechanter charges up to 3 stones with magic, adding 1 point of force damage to each stone thrown or launched with a sling.  The attacking kobolds must be within 5 feet of the Stonechanter to gain this benefit.  This magic effect ends after the stones are used in an attack roll, or at the beginning of the Stonechanter’s next turn.  Stonechanters may not stockpile these stones.

Kobold Mushroom (1 or 1d4-1 mushrooms).  The kobold may eat one mushroom to regain 1 hit point and gain advantage against all Wisdom Saving Throws for one hour.  The kobold may eat another mushroom on a following turn and benefit from the hit point recovery, but may not stack the duration benefit for the Wisdom Saving Throw bonus.
