Vaal Pact, Eldritch Battery.
Freezing pulse builds are in the game from closed beta I believe xD but I really wanted to give this skill a try and my conclusion is that it makes a very easy build, not really expensive and with a great clear speed.
Acrobatics, Eldritch Battery, Phase Acrobatics.
Budget Arc build 12k dps using a 4Link,really good for new player 1-2 exalted should be enough to gear up and play every map on PoE. Great synergy in group play and Awesome build for Solo player.
