Wyvernazon

This is a wyvern shapeshifter Amazon build that uses Oil Barrage to consume power charges and proc Elemental Surge on each hit.

We generate power charges with Devour while clearing and Lingering Illusion or Siphoning Strike on single target after shocking the boss (quarterstaff in weapon swap).

For clear, I simply use the wyvern default attack Rend with power charges.

Use Pounce to move between packs. With high enough crit chance, you can also use it with Shocking Leap support to create shocked ground, which allows for easy power charges on bosses via Siphoning Strike. Socket Voltaic Mark into Pounce to make it easier to electrocute bosses, using Electrocute support on Elemental Surge.

Use Ailith's Chimes + Culmination II supports on Wind Dancer. Build combo by attacking with Rend and whenever anything hits you, Wind Dancer will go off and generate power charges automatically.

Use Electrocute support on Oil Barrage and Herald of Thunder to electrocute enemies. This will generate a frenzy charge from Combat Frenzy and grant you extra skill speed from Charge Regulation. Electrocute also makes the enemy take 20% increased damage with the Electrocution node on the tree.

Lavianga's Spirits makes your mana flask permanently active. This allows you to take advantage of nodes on the tree that grant effects while your flasks are active, such as Stimulants, Crystal Elixir, Wellspring, and Imbibed Power.

Couture of Crimson allows you to overflow your life from leech, giving up to 1.5x your normal maximum life. It also gives up to 15% increased life (or more if corrupted). This synergizes with Amazon's Mystic Harvest to leech from elemental damage, and avoids the downside of Stalking Panther, since Couture of Crimson has no evasion.
