I'm currently learning N3 level so I'm not sure if this is something I might haven't learned about. I never know we could put を like this.
This is a sentence from an e-dict so it should be correct.
当たるを幸い、彼は敵をなぎ倒して He struck down every foe that came his way
当たるを幸い is the part which confused me.
Normally it would be [[object を verb]]. Could someone help break down this sentence? Thanks
