Quillathe is too aggressive and arrogant to consider surrendering until things are more dire, and a man with no weapons (except her own whip) just isn't that intimidating. Actually, she's tired of running, so she stays and full attacks.
Rapier (at +15/+10). 16+15=31, 3+10 = 13. One hit, one miss, for 2d6+2 = 10 damage.
Bladed Whip (at +16). 17+16=33. One hit, for d6+1 = 6 damage.
Sneering at the offer for a truce, Quillathe attacks with her unorthodox whip and rapier combo, lashing at Cyme's arms with her whip to try to open up his guard, then thrusting with her rapier for his vitals. Cyme is not worried by the light cuts from the bladed whip, and he deflects a thrust aimed for his heart into a simple graze along his leg.
Cyme is at 30, Quillathe at 12.
