I did a tactician permafrost xbow build for 0.4 and I had a blast. Shotgunning your way through packs of mobs was really fun, and it was also a solid boss killer. During act 3 I managed to craft an awesome xbow with +3 skill modifier,+% phys damage and added phys damage, it lasted me to mid mapping and sold it for 3 div.
I farmed the Ultimatum trial for those runes you get at the end, they sold for ~10 div each and I could do them in around 15 minutes, it was a good money maker. It was also great to run Abyss, and got a couple of omens I sold for 100 div.
I tried whiplash and twister with ice-tipped arrows hunter up to act 3, can someone explain me why ice-tipped arrows works maybe 2 out of 3 times ?
