Tried converting my trap rat into a bow dudu tonight with some decent success. It should be noted I have about 25 of the charms, and 280 sigs eaten so I am sure this greatly helps.
Skill plan:
Smax Symbiosis, Life Shield, Force of Nature, Nova Shot.
7 into laughing ghost (to max elfin wep 1000%), 40 into elfin wep, 26 elven song (20% avoid), 1 into acid fiends, and 1 into all other pre-reqs.
Gear:
Coldhunger helm, Erawan body armor, life crushers for boots, ring of disengage, rare ring, rare ammy, crap quiver, and a nice Windforce I found which works well with Nova shot, my favorite of the skills so far. I switched out of my crafted gloves to Pollice Verso TU6 gauntlets for the mana after kill - since this was my biggest problem. Even with 120 MaeK and 6% mana leech I down my mana sooo fast. Nova cost 370 per attack of 5400 mana atm.
I can run tcow, destruct diablo, and dest nihil no problem (minus drinking 12 mana pots a run) with my current setup, Toraja Jungle was a little hairy and Teganze is slow going. I know I'm not optimized for bow dudu setup with my current gears but thought I would share. Will be trying a few other areas shortly.
Any suggestions on a source of mana gain for bow dudu, especially against single target? Ber craft runes perhaps? Thanks, and hope this helps.
