Can anyone tell me what dungeon drops this? Its lvl 17 bow. I got one of this but I forgot where it drops. I need one because I think its more stronger than Artemis bow. Greatbox has +5dex and thats huge.

Kishinden. Run it on hell with like 5 people and ID the gold drops, silver if you're feeling lucky.

If you're already high enough level to equip Artemis, consider using Fuedou Bows instead since they're cheaper than either of the aforementioned. Though they do slightly less damage than Greatbows, skill evo V on certain skills can make the difference.

i have greatbow +30 but it isn't lvl 17, i think it's lvl 12 or 13, i forget and you don't need to go to kishinden in hell mode to get that
