Returning bowmaster low damage range Recently have returned to maple after 2 years, and i'm playing on my 155 bowmaster. I have about 1b meso's cash but when i tried to do horntail regular and chaos zakum i got wrecked. The guy i was partying with was also outdamaging me despite being a level 140. My range is What do you suggest i spent the 1b on to get a better damage range than 19k? I recently heard of the star stystem and starred my utgard bow to +5 which helped a bit. gear setup:http://imgur.com/a/d7Lbc Greatly appreciated Thanks
