Weapon and Armor:
The best choice for armor is Scar Patterns because they add bonus energy which is quite important in this build.
For weapon use Staff with bonus to energy and HP. Staff should have "Improve skill cast/recharge using Curses".
How to play:
Conception is simple. Find target and cast Chilblains and Signet of Agony to make conditions on you. Then use Plague Signet or Plague Sending depending of situation - if there is only single target use Plague Signet and if there are more foes around your target use first Plague Sending one or even two times if you have enough HP.
Use Strip Enchantment to take off enchantments like Healing Breeze and to heal yourself as well.
Try to use Leech Signet to gain energy for free and Signet of Humility to disable foe's elite skill.
Of course if someone from opposite team makes condition on you, try to transfer it back.
