Kathil twirls her short sword ostentatiously in her off-hand, then clips with both her swords - snicker-snack - at the creature in front of her and to the left, currently threatening both her and Aerith (D).
Attack, weapon hand: 1d20 + 5 ⇒ (20) + 5 = 25
Attack, off hand: 1d20 + 3 ⇒ (15) + 3 = 18
Crit Check for longsword: 1d20 + 5 ⇒ (7) + 5 = 12 ... hit
damage, weapon hand: 2d8 + 6 ⇒ (7, 3) + 6 = 16
damage, off hand: 1d6 + 3 ⇒ (4) + 3 = 7
Both attacks hit, the swords slicing through the creature in both directions. She draws back the swords with a flourish.
"Hah!" she exclaims, almost involuntarily.
Creature D is (very much) down.
