Do you know how twisted bow works? The higher magic defence npc has the higher you hit. But the slayer helm i needs a fix, i do agree on that.
Yes ofc i know how twisted bow works. And ive tried nearly every boss with the exception of bosses in wildy. Even tried on the higher level monsters (demonic gorillas, mithdragons, etc) and then i switch to blowpipe it the kill time is usually 15-30 seconds faster
