I am wondering if anyone can help me with choosing weapons for Riblayn, my Reborn Serpenth. He is Health: 41/41 Strength: 38 Defense: 42 Intelligence: 49

and has a balrog, wand of power, light blade, blood halberd, dark matter crystal sword, The Replikaxe, item Hunters Staff, and lizard skin. I beat about 42 mini gelatins, but i can't beat any medium foes....what weapons could i use that are better than the ones i have now? (not including my Balrog)
