Destiny 2 Titan BuildIcy Juggernaut

Icefall Mantle got a rework this season and it's pretty significantly changed while still preserving the juggernaut feeling it's supposed to without making you feel like you're moving through molasses. So what does it do? From the DDC:

• Getting 2 stasis kills within 3 seconds of each other gives a stack of Frost Armor. 
• Replaces your barricade ability with Glacial Guard which gives you max Frost Armor stacks and creates a freezing pulse around you. You must be on the ground to cast it. 
• Restores 10 HP for every stack of Frost Armor gained. 
• Only works with a Stasis Super equipped. 

So Frost Armor comes up a lot in there so it's worth explaining how that works. 

• Each stack of Frost Armor gives 4.5% damage resistance. 
• At base, you can have 5 Frost Armor stacks for 22.5% damage resistance. 
• At base, Frost Armor lasts for 9 seconds. It refreshes when you gain more. When the timer expires you lose all Frost Armor. 
• With Whisper of Rime equipped, max stacks go to 8 for 36% damage resistance with a duration of 13 seconds. 
• The most common source of Frost Armor stacks are Stasis Shards which are mostly generated by Harvest Aspects (Tectonic Harvest on Titan).

Frost Armor isn't the highest damage resistance but it can have very high uptime. Generally, if you're doing somewhat challenging content I recommend running Whisper of Rime for the uptime and extra resistance. Max Frost Armor is more damage resistance than max Resilience. 

The biggest feature of this exotic is that it provides healing whenever you gain Frost Armor. Stasis does not have a lot of healing so this is pretty significant.
