As a Red Death owner, I can say that the weapon has high points and low points. The big money is obviously in the guaranteed heals and faster reload speeds when you land a kill. This makes it a very useful tool in Crota's End. However, since Bungie can't balance a seesaw to save their lives, they decided to NERF the Red Death's damage in exchange for a slightly higher RoF, which made absolutely zero sense. In the end, the RD just fails to bring the satisfying stopping power seen in other exotics like the Vex, Suros, Hawkmoon, Thorn, etc. If you use it as a self-healing machine and leave the heavy duty work to your specials/heavies, you'll be satisfied. If you pick up a Red Death expecting it to mercilessly bulldoze through majors and ultras like other exotics, you may be a little disappointed.

It turns you into Wolverine. Per kill you get healed so in something like hard mode Crota it's a godsend, that's assuming you can't heal in other ways. Some exotic helmets heal you per orb pick up and if Crota is like VoG the raid gear probably has a chance to spawn orbs perk that's based per precision kill or per melee kill.

Just the healing factor

Use in pvp. If you get good with it.. Full health after each kill!

Basically it helps during Crota since you don't regen health and the perk on it heals you with every kill.

it's PERFECT for any hunter. guaranteed healing + staggering enemies = <3
