Chase setup: Natalya starts with 3d6x5ft of gap, needs 200ft of gap to lose the pursuers, take them out with trickery or violence, or make it 500ft to the river, where she can lose them. Natalya takes 1 point of system strain for each round of sprinting (move as Action) after the third to represent exhaustion.
Natalya: 16 AC; Mage Fray ("curse") auto hits for 1d4 at 60ft. Her speed is 30. She can Punch, +2 hit, 1d8+1 damage.
The 3 dogs have 12 AC, one hit die, +2, 1d4 (stats as small pack predator) - speed 40.
Dog 1: 2 HP
Dog 2: 6 HP
Dog 3: 3 HP
The two guards as Elite Guards (book page 283) AC 18, 3 HD, +4 atk and 1d8+1 dmg. It is in Natalya's best interests to stay the heck away from them, they will mess her up.
Guard 1: 13 HP
Guard 2: 11 HP
Rolled 3d6*10 for Natalya's lead, got 16. 160 ft seemed like too much lead for any excitement, so I cut it in half. 80ft gap to start with, 420 ft to the river.
Round 1: Everyone sprints. Natalya moves 60ft, 360ft to the river. Dogs close the gap to 60 ft. Guards still 80 ft behind. Natalya curses dog 1, 2HP damage, Dog 1 falls.
Round 2: Everyone sprints. Natalya moves 60ft, 300ft to the river. Dogs close the gap to 40 ft. Guards still 80 ft behind. Natalya curses dog 2, 1HP damage.
Round 3: Everyone sprints. Natalya moves 60ft, 240ft to the river, halfway there. Dogs close the gap to 20 ft. Guards still 80 ft behind. Natalya curses dog 3, 2HP damage.
Round 4: Natalya moves 30ft, 210ft to the river. Natalya curses dog 3, 3HP damage, dog 3 falls, Natalya prepares to punch dog 2. Dog 2 closes. Natalya punches Dog 2 (18 to hit), does 2HP damage (4/6). Dog 2 snaps at Natalya, (10 to hit, miss). Guards close to 50ft.
Round 5: Natalya curses Dog 3, for 1HP (5/6). Natalya punches dog 3 (22 to hit), 2 damage, dog 2 finally falls, Natalya moves 30ft., now 180ft to the river. Guards sprinting, close to 20ft. from Natalya. They, like the dogs, are ominously silent.
Rounds 6-8: Natalya sprints 180ft to the river, guards hot on her heels the whole way. For three extra rounds of sprinting, she takes 3 system strain.
Natalya dives into the river. The guards pull up on the bank just behind her.
