Its not used for the defense. Well, void melee is used for duels and magic based monsters normally. In a duel, two 50 specs wins the match. Void's magic defense is plenty for killing bloodvelds or whatever. Heck, at 90 mage it can do well at waterfiends! No offense, But I really stopped taking you seriously when you said void magic was the most useful. One of my friends tested it out at Steel Dragons and ahrims/infinity outdoes it by far. Unlike range and melee, void mage does nothing to your damage. It just adds a tiny tiny bit of accuracy, which is nothing compared to standard robes. Void Range is arguably the best void set. I'm not sure about it in PvP (But hitting a runner with a void 45-45 Dbow spec sounds neato) but in training it helps your XP alot. Your bow gives enough accuracy to hit stuff like Bloodveld or Yaks consistently and the extra damage is great. Plus you won't be taking damage either way because of safespots. I like the mace too for DMs and dueling, but Ice Blitz is beter than Entangle+Claws
