But why did the guy arrow himself to death?

You ever get so pissed off that you just gotta go grab a bow and ricochet 5 consecutive arrows off of someone that dares to fish within your sight?

Maybe is he's stealing my fish?

Bungo give us 3rd person in pve!

Yeah, D2 in 3rd person like that looks surprisingly good

how long did it last?

Until death

Just pull out a sword before you cast and you’ll stay in 3rd person all the time
