Thanks for the hookup Krag...
Man, tornado shot is nice. It feels like I'm in an FPS using a shotgun, lol. One click, BANG, screen is cleared. I'm at level 50 in Act 3 Cruel, and Tornado shot is listed at 950 tooltip DPS. Well, that 950 is each arrow, but with GMP that equals a total of 20 arrows. 5 for base skill + GMP that 100% pierce, then those 5 split into 3 apiece that shoot out in all random directions.
So at max effectiveness, assuming I shoot into a large pack of mobs and every arrow hits something(not even counting that the first 5 can pierce, and I'm using a pierce gem on the others) Thats 20x950 = 19,000 DPS per shot. It's even pretty decent against single-target rares and bosses, as 2-4 arrows will usually hit 1 large mob if you fire just slghtly behind them. I tore down Cruel Vaal before Vaal could even disappear once, Vaal tried to summon 2 waves of mobs, but the Tornado shot was mowing them down all over the screen, and it mowed down Vaal as well in about 10 seconds.
Good stuff. Thanks to whoever put the insane physical damage bow in the Beyond guild stash. It was a level 34-ish bown with a +119% physical mod, and + 11-24 extra physical too. It pretty much tripled my DPS when I started using it, and still haven't found anything better in 15 levels.
