Brownie

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

Hide In Plain Sight. If the brownie is in dim light, tall grass, or heavy undergrowth, it can make itself practically Invisible. The brownie can use the Hide action even if it is being observed or there is nothing to give it cover.

Shortsword. Melee Attack Roll: +6, reach 5 ft. Hit: 1 Slashing damage.

Sling. Ranged Attack Roll: +6, range 30/120 ft. Hit: 1 Piercing damage.

Spellcasting. The brownie casts one of the following spells, requiring no Material components, using Wisdom as the spellcasting ability (spell save DC 12):

At Will: Dancing Lights, Thaumaturgy

1/Day Each: Protection from Evil and Good, Daylight, Confusion, Dimension Door

Calm Animal. Charisma Saving Throw: DC 15, one Beast within 30 ft. Failure: The target is Charmed for one minute. It remains where it is and does not attack or flee, but is not helpless, and can defend itself normally if attacked. If the beast takes damage, the enchantment ends on the creature. Success: The target is immune to this effect for 24 hours.

Uncanny Dodge. Trigger:  The brownie is hit with an attack. Response: The attack deals half damage.
