In a future patch we will be implementing the Sorcerer skill Disintegrate and its specialization tree! By default Disintegrate is a hybrid skill which deals both Fire and Lightning damage.
The specialization tree for Disintegrate is currently in the design phase. Due to the unique properties of this skill making its implementation more difficult than most, we are not yet ready to confirm which patch it will be part of. Let us know whether you’d be interested in us posting a preview of this skill’s tree on our website prior to releasing it in a patch!
As an aside, we had previously shown off Static before announcing that during our playtesting we had chosen to withhold the skill to work on improvements to it. We continue to iterate on both Static and its tree, and they will be included as part of a future content patch.
