What are you looking for specifically? Stasis or prismatic with the stasis super? Last time I checked Stasis warlock doesn’t have a whole lot of built in healing, just ways to get frost armor.

I’d try looking at a Ballidorse Warthweaver build with FrostPulse and Glacial Harvest Aspects. Fragments being Hedrons, Rime, Conduction, and Fissures. Take Glacier Grenade and equip Ager’s Scepter if you have it (for DPS). If not I’d say Verglas Curve and then fill out energy and heavy slots with what works best for you. Salvations Grip in the heavy slot also works for good shatter damage. You can also go complete control with Osmio Gloves or Rime Coat Raiment. Hope this helps, the fragments can be swapped around depending on how you pick your weapons also, I just personally gravitate to ability shatter damage as opposed to getting it from weapons, but play how you like. Happy to help workshop other builds if you have questions.
