Puncture any good ?

"

Puncture is the best single target skill in the game. It's amazing in a physical bow crit build. It will onehit many bosses and exiles(they move a lot so they will die fast).

I can agree with this statement. Puncture is somewhat situational but in most cases it does ridiculous damage.
If I compare puncture with frenzy I like puncture more, because its damage against strong enemies is incredible, it "feels" better to use and inflated attackspeed is also not that great. Also frenzy requires you to invest a bunch of skillpoints and the wind up mechanic is annoying (imo).

I see 2 ways of using puncture:

1, crit build, makes sense ofc

2, high physical build (which got buffed a lot with the new support gem)

Interesting to know is, that VULNERABILITY RIDONKULOUS improves puncture, because it scales the damage to the square:

-initial hit does more damage
-Dots do 40% more damage

I guess many people are not aware of the Dot increase of vulnerability.

You WILL oneshot bosses without crits with puncture + vulnerability.

Btw.: Dont unerestimate punctures scaling. It gives a lot of physical damage + the %Dot also increases.

PS.:

"

First it increases physical damage, which increases the DOT damage because your hit is bigger, next it takes more DOT damage and then again with more dot damage due to that damage being physical.

So I learned something new^^
Also I did not know that knock back works well with puncture. I exspected it.
