This is most likely the strongest exotic to use with a warlock stasis build at the time of writing this. There are different approaches you can take with the build, differences between a turret build, or a pure freeze build, in either case, they can both perform amazingly. Osmiomancy’s grant an extra coldsnap grenade, which really helps us aggressively freeze everyone on the field. They further enhance coldsnap grenades by extending the range they travel, and improving their tracking capabilities. To top it off, they can generate grenade energy by freezing or hitting enemies, this makes the turret build exceptionally powerful.
Aspects
Iceflare Bolts is a relatively simple aspect, shattering a frozen target will spawn seekers that track, and freeze, nearby enemies. Effectively, you can keep freezing enemies permanently just by shattering frozen targets over and over again. Bleak Watcher is what allows us to use and create stasis turrets. Charging your grenade will create the turret where the grenade lands. The turrets can be destroyed by enemies if it take enough damage, so ideally, place them outside of enemies line or fine or area of effect attacks to maximize their duration. Enemies don’t target the turrets directly. This allows our “grenade” to effectively slow and freeze a much larger group enemies as opposed to being thrown normally.
Fragment
Whisper of Chains helps with survivability just by standing by stasis crystal or frozen enemies. Since we will be freezing enemies, and our turrets are also freezing enemies, there should be no shortage of stasis crystals or frozen enemies to keep the damage resistance. Whisper of Fissures is a more offensive perk that amplifies the damage and damage radius of shattering stasis crystals. If you don’t need the damage reduction of Whisper of Chains anymore, shattering the crystal will do good damage. Whisper of Torrent is another grenade energy generator for the build, to stack on the rest of our grenade energy generation to keep turrets up. Taking damage will generate grenade energy. This is why keeping a high Resilience stat to reduce the incoming damage, and a high Recovery to get back into the fight, is important. Whisper of Shards not only provides some resilience, but is another grenade energy generator. Shattering stasis shards will generate grenade energy. The more crystals you shatter, the longer the recharge rate will last.

This is an extremely strong shotgun to use, not only for it’s freezing effect, but for how easily it can deal with champions, tough enemies, even add clear. For this build, its effectiveness at freezing enemies makes it ideal. It can perform in any difficulty aspect of the game which makes it the perfect weapon to use. The freezing effects are particularly strong against Unstop champions, but freezing any champion type makes dealing with them a breeze.
Bloodfeud is a strong SMG that can roll with Headstone, and your choice of 3rd column perk. I like Pugilist for more melee energy.
The strongest stasis fusion rifle. Lowest charge time, and can have Chill Clip which slow/freezes enemies effectively.
An aggressive frame rocket that can have Chill Clip. This paired with someone using Gjallarhorn enables multiple freezing and shatter damage from chill clip.
     
Headstone // Chill Clip
Any weapon with the above perks will benefit the build. While not needed, the ability to freeze/slow any enemy is very strong, and with a stasis build, ties in quite nicely. Headstone will create a stasis crystal on every precision kill you get. Chill clip will apply slowing stacks on enemies, and with enough slow, it will freeze the enemy in place. Both of these effect benefit the build and tie in to our fragments/aspects of choice.
