Excerpt from "'Should I Buy It?' – Hard Light & Other Exotics"
Apotheosis Veil is one of four Warlock helmets, one of several (3) which are subclass-neutral. Apotheosis Veil regenerates your health when your Super is activated. It also grants Infusion, which has notable use in Crota's End (Hard Mode).
Other than Crota's End HM, it's a questionable choice to make over other Warlock Exotics. It does make for an excellent panic button which could turn a fight, but...that's its limit. A reactionary, rather defensive Super use. The hidden cost of using an Exotic is that you're choosing it over every other Exotic. Apotheosis Veil is simply overshadowed by alternatives.
- Infusion: "Replenishes health each time you pick up an Orb of Light."
- Since your health doesn't regenerate in Crota HM, and there's no Chalice, this talent is treasured among regular Crota HM runners.
