Sundering Zodiac Longbow of Fortitude
Piercing Damage 15-28(max) Required 8!
+15% Damage when in a stance.
Armour penetration 20% (20%chance)
+30 health
35-40kish, maybe a little more with those mods (ack 20/20 on a longbow!!! I wouldn't pay extra for that, honestly). I bought a r8 stance one for 20k a while back.
