I finally got the Cenotaph to drop for me yesterday, and I gotta tell you - it’s a blast in PVE with coldheart and an ionic trace build. Double arc reserves and arc siphon with blinding explosions on my arc subclass is nuts! strong single target damage as well as crazy ad control, you’ve gotta try it if you happen to have the helmet.
The new exotics drop from the Vex invasion event on Neomuna as well now. Its how I got the latest ones on Titan and Hunter.
There is a Discord bot that can ping you when the event is about to go live. Assuming you have unlocked all other Warlock exotics, the first completion will give you the helmet.
EDIT: Added link to Discord server
Woah, didn’t know about it dropping on the vex invasion event! How would one set up this bot?
