While certainly not as optimal or even ideal depending on the content compared to their Magicka counterparts, Stamina-based healers have long been around in the background of the PvE combat scene as a very niche or "off-meta" spec.
With the recent hybridization of things such as Armor, Passives, Item Sets and a few other changes that have happened since Update 23, the viability of Stamina healers has only increased and some have even cleared Trial content such as Cloudrest Hard Mode or pre-Halls of Fabrication Trials.
The Perseverance build is intended for use in primarily 4-man content including Dungeons and Arenas from Normal to Veteran Hard Mode difficulty. Not recommended for Trials after Cloudrest.
Recommended race for this build is Bosmer due to their innate Max Stamina and Stamina Recovery passives. The latter will help if you decide to switch foods.
Recommended Mundus Stone is The Serpent or The Ritual depending on your spec.
Recommended potions for this build will be Essence of Weapon Power.
Recommended food for this build is Artaeum Takeaway Broth or any bi-stat food (Health + Stamina) for content that requires you to do so. You can also do tri-stat or recovery foods if required.
