What Bow Did I used to KIll Sargon?

Somebody asked me(Wakaole) "What bow did i used to kill Sargon "?? yeah ..I normally use predator bow and on rare occasion some other long bow...and u all know ..I`m the dude who uses short and long bow when ever he pleases..but in that particular time i used that freaking weird looking bow LOL..
Why???..answer-->because of the damage, acceptable speed and because of low speed it spend less essences.
