Longbow attack against Medium Black Ant 1:
(15) +7 = 22 To Hit
(2) +3 = 5 Piercing damage

Horde Breaker additional attack against Small Black Ant 2:
(1) +7 = Auto miss
32 arrows in quiver, 1.5 arrows recoverable

Vicious Mockery, 3 damage to ant swarm 1 if it fails its save.

Steam moves to P6, which should be within the edge of 60' to Ant Swarm 2. If not, she'll move to O6, which should definitely be.

Bonus action to move the sphere to K4 and ram it into Small Black Ant 1. It attempts a Dex save DC 14, taking (14) Fire damage on a failed save or half that much (7) if it succeeds.
Again, any creature that ends its turn within 5' of the sphere attempts the Dex save DC 14, taking 2d6+4 Fire damage if it fails or half that amount if it succeeds.

She casts Sacred Flame on Ant Swarm 2 in E7. It attempts a Dex save of DC 14, taking (11) Radiant damage if it fails.

Longbow shot at Small Black Ant 2:
(8) +7 = 15 To Hit
(2) +3 = 5 Piercing damage

Longbow shot at Small Ant the other:
(12) +7 = 19 To Hit
(6) +3 = 9 Piercing damage
30 arrows in quivers, 2.5 recoverable

Attacking with swords
To Hit:
Main hand 19
Off hand 1

1d6+2=6+2 damage from the saber

I know the ball can't actually do that, but it makes for good flavor.
Sphere moves to N6 and rams Swarm 2. Swarm makes a Dex save DC 14, taking (7) Fire damage on failure or (3) on a success.
Creatures that end their turn next to it Dex save DC 14, taking 2d6+4 Fire damage on a failure and half that amount on a success.

I also know Steam can't actually hit Ketha unless she tries or casts Burning Hands.
Eldritch Blast at Swarm 1:
(9) +4 = 13 To Hit
(1) +4 = 5 Force damage

Alright, so Parveth is making 3 attacks this round. Yes, 3. One normal, a second as a bonus action with Two-Weapon Fighting, and a third that's free from Horde Breaker.

Man, I'm going to run out of clever titles really quickly.
(5) +7 = 12 To Hit
(1) +4 = 5 Force damage

Flame sphere moves from N6 to N4 and rams ant swarm 1. Ant swarm 1 must attempt a Dex save DC 14, taking (12) Fire damage on a failure, or (6) on a success. If a creature ends its turn next to the sphere it must attempt a Dex save DC 14, taking 2d6+4 Fire damage on a failure or half that amount on a success.

Parveth moves from N3 to P5.

Cutlass attack:
(11) +5 = 16 To Hit
(3) +3 = 6 Slashing damage

Two Weapon Fighting bonus shortsword attack:
(8) +5 = 13 To Hit
(5) = 5 Piercing damage

Steam takes her action to disengage, and moves from P5 to I5.
The ball of flame moves from N4 to O6, and rams into the swarm. It attempts a Dex save DC 14, taking (7) Fire damage on a failure or (3) Fire damage on a success.
If a creature ends its turn within 5' of the sphere, it attempts a Dex save DC 14, taking 2d6+4 Fire damage on a failure or half that amount on a success.
Parveth finished her turn before the sphere was moved there, so...yay rules.
