When I have mentioned it, some people have been dismissive of the ability to use life gain on kill Cinderswallow to solve one of EA totem's biggest build problems: life sustain. This skepticism is understandable as it was one of the most nerfed items in the 3.16 flask "rework," gaining a huge flask sustain penalty as well as being reduced to only allowing sustain of one of life/es/mana rather than all three.

However, I think a lot of people don't build around one of the mods on the flask that was buffed: it now gains five charges when you "consume" an ignited corpse.

Corpses may be consumed by Offering skills, Devouring Totem Dominating Blow, The Devouring Diadem, and Void Sphere.

In this build I use CWDT Void Sphere as both crowd control and also go generate charges for Cinderswallow.

I demonstrate in this video a combination of mechanics which can allow EA totems to survive in environments that can deal very high damage to players very quickly.

1. Cinderswallow Urn
2. CWDT Void Sphere acting both as crowd control, and as charge generation for Cinderswallow Urn
3. Totem Taunt mastery

My version of the build has relatively mediocre evasion and armour due to using Purity of Elements instead of Grace, and I find that this flask has allowed me to start leveling solo pretty readily. I do have very low xp in this video due to running a bunch of hard invitations immediately after hitting level 96, so it's obviously not a tanky build, but I find the flask allows very decent life sustain during mapping and other non-boss challenges.
