Yeek!
I'm guessing I over did it. The door's just hardwood, like structure rating 7 and armor rating 6. That's enough that I didn't think the beat-up bot could just pounce it down, but it's not a blast door or anything.
If you want to retcon the size of the charge, I'm with that, but otherwise, BooM! There goes the room!
Door soak!
DV =21 x2 because it's explosive - 42DV
6d6.hits(5) → [5,1,6,5,4,3] = (3) so, net of 39 DV, making a 5 meter hole in the wall.
Floor will soak at only 1x because it wasn't tamped to blow the floor.
soaking 21dv -4dvx1m damage with 12 armor
12d6.hits(5) → [3,3,5,4,2,3,3,4,3,2,1,2] = (1)
whew. with 11 structure rating, 16DV only makes a 1 meter hole in the floor.
Wall to the conference room takes 21 -4x2= 13DV
8d6.hits(5) → [1,4,6,1,6,5,6,3] = (4) 9DV is just enough to make a 1 meter hole in a 9 structure.
Ceiling also takes 13DV
12d6.hits(5) → [2,2,6,5,5,3,4,5,1,1,6,1] = (5) soaks down to 8DV. holds, but is damaged.
Meanwhile, inside the room, 42DV becomes a 21DV flechette spray.
Ms. Phipps is 4m from the door, in partial cover, but unaware of the attack, so she auto-parrys with her face.
Soaking 17(f) +5ap.
15d6.hits(5) → [2,6,3,3,3,6,5,1,1,2,2,5,5,4,3] = (5)
She takes 12P, and is scrapped. Poor Ms. Phipps.
