You could rethink devotions to include Bard’s Harp (or possibly Tree) for energy. That would pretty much solve any energy issues.
Arcane Spark in medal is pretty good as well but don’t think it will handle energy regen for this build by itself.
From what I remember the old build thread posted on here was called ‘Sting like a Rock’ and had a lot of good info.
