Nidallas Hidden Hand Lowers DPS of Procs on PIERCE builds?

I thought it would take 33% of the full piercing damage ( after adding 700% pierce modifier)

Now I am thinking that it actually converts the base piercing damage and than whatevers left, the 66% is than modified by the Piercing modifier)
and the converted gets modified by acid/poison damage (which i do not have any of in a piercing build.)

You don’t have to pick it to put points into the other nodes.

Thanks for the reply,

I think im just gonna go with Blades of Wrath for AoE and use Ring of Frost for CC

The damage is not nearly as good as I thought, and BoW is stronger for AoE damage

My opinion is that it doesn’t reduce it drastically.

But the slow from the proc makes up for whatever loss in damage there was.

Its slow reduce enemy attack speed too?:confused:

Slow = Total Speed -%. So yes, it’s attack speed as well.

Thanks.
No wonder I saw a lot of non-acid builds put 1 point into it.
