This is the Titan version of Crest of Alpha Lupi. See the Hunter version!
Excerpt from "'Should I Buy It?' – Patience and Time & Other Exotics"
Crest of Alpha Lupi is one of two Titan chests, with The Armamentarium being the other. CoAL grants two benefits to max ammo (Auto Rifle/Special). More importantly, your revivals are much quicker (including your own).
The main talent is Keeper of the Pack. Revive teammates faster. Be revived faster. More Orbs generated with your Super. This is one of the best all-around perks for an Exotic, also featured on Light Beyond Nemesis (Warlock). Excellent for PVE, also useful for PVP in Trials of Osiris, Skirmish, and Salvage.
Its use in Nightfalls alone is worthwhile. In PVP revival gametypes (Trials / Skirmish / Salvage), CoAL can be a savior. In PVE, it'll constantly prove its worth time & again when with a group. It's a high-utility Exotic that deserves strong consideration.
