If I understand this correctly, anyone withing melee range will be torn apart by dart-speed attacks that are extremely accurate and powerful. And anyone not in melee range will be hit by incredibly powerful and accurate magic attacks. So, basically you're screwed no matter where you are. But I got this idea, Why not have a guy on your team use ancient magick ice spells? Or possibly entangle. (Note: I've never been to the saradomin area of GWD, I made this because I can't believe no one thought of this before)
