Help With EA Build PLz

I've made an explosive arrow character for high level pvp I was hoping someone could help me out for what links to use with explosive arrow. What single target to use, what traps to use, or curses they may help in arena and dueling would be amazing. I went high life and hp regeneration little aoe little damage mostly hp and hp regeneration with blood magic. I don't really know what I'm doing I win a lot of duels but arena I get owned by the good players so what am I doing wrong. I don't know if it's my build or what. Any feed back on explosive arrow build high level pvping would be amazing or any info at all would be amazing on explosive arrow build.
