This build is from patch 0.8.0d (We are now in 0.8.1c)
In the release of patch 0.8.1 they changed prefixes and suffixes around. Some of the items in this build cannot be crafted in the same order or even in the same slot as is.
Ill try to update this build soon
For Now when it comes to lightning i recommend @FoE nova boi
Yes it scales with both of those as well as spell damage
Penetration is infact very powerful. Add some if you like it will increase your DPS, i didnt find that i needed to change anything around for it at the time since the DPS was already accomadating.
Ill probly get this one wrong, but i believe bosses DONT have any resist they have a for of DR. but Resist can go negative so by getting penetration your still doing a “more” damage modifier.
Ones going to be very hot, the other ice cold
This probly related to the +adaptive spell damage while channeling on chest/helm as well as Damage increase while channeling since we are not channeling during teleporting
