Introduction[]
In Goblin Slayer (Series), Goblin Slayer dodges an arrow at point-blank range. I'll be calculating his reactions and combat speed.
Calculation[]
First we need to find the width of his helmet visors.
Scan 1
Goblin Slayer = 177 cm (I'll assume he has the average human height)
Helmet Visor Width = 1.74 cm
Horn Width = 6.61 cm (I'll use this later to find the distance he moved his head)
Then we can find the distance between the arrow and his face.
Scan 2
Helmet Visor Width = 1.74 cm
Distance = 2.82 cm or 0.0282 m
Now we just need to find the distance he moved his head.
Scan 3
Horn Width = 6.61 cm
Distance = 41.25 cm or 0.4125 m
Finally we can find his speed. The goblin's weapon looks like a small recurved bow, Ricsi-viragosi calculated the speed of the arrows of that bow at 15.584 meters per second, as goblins are weak and small.
Timeframe = 0.0282/15.584 = 0.0018095482546201 seconds
Speed = 0.4125/0.0018095482546201 = 227.96 m/s
Final Tally[]
Goblin Slayer's Reaction and Combat Speed = 227.96 m/s, Mach 0.66 (Subsonic+)
