I looked up the raw, and the spell
is actually written as "Magic Bolt" (both in this chapter and on his character sheet in chapter 2), but as some people were suspecting, the description is mistranslated. Instead of "Counter the arrow towards the target", it should be more like "Flies/Unleashes towards the target's location".
The raw page in question for this chapter:

As a side note, the "スッ" sound effect on page 10 is also mistranslated. Instead of "take", it should just be used to indicate movement (in this case, the MC raising his hands to pray for taking the goblin's life).
