So, here's what ended up happening in that post...

Backstabs tries to do what she does best!
Attack roll = 4 + 9 = 13
Enemy's dodge roll [color=ed1c24]1[/color]

Mini crit for...
19 (max damage) - 1 (defense) = 18 damage.
Fire damage = 3 * 0 (fire resistance) = 0 additional damage

82/100 HP left

Golem attacks Robert in blind rage!
Golem's attack roll = 19 + 15 = 34
Robert's dodge roll = 7 + 7 = 14

Golem hits for....
13 + 1d3 (3) = 16 - 8 (defense) = 8 damage
11/19 HP left

Robert randomly stabs something with his rapier!
Robert's attack roll [color=00a651]20![/color]

Robert hits the golem for 15 (Max weapon damage *1.5) + 8 (DEXmod/2 + STRmod/2) = 23 damage!
+ 3 * 0 (fire resistance) fire damage from the dragonsteel

57/100 HP left.

and then the golem starts to flee.
