Destiny 2 Titan BuildAetreas' Unbreakable Vexcalibur

The Unbreakable Bulwark gripped in an Unstoppable Fist

Yeah, I know the hotness on Titan is Striker in Episode: Heresy. But Bungie really seems to want the Unbreakable aspect to be strong. (Not that I mind, I've enjoyed it on certain builds since Episode: Revenant.) To this end, the key buffs I would point out being reflected in this build are the following:

As per Destiny 2 Update 8.2.0...

Unbreakable: "Increased the rate that the Unbreakable offensive throw charges up when blocking damage."

Ursa Furiosa: "Blocking damage with Unbreakable now returns grenade energy instead of Super energy" , "Grenade energy is returned at the end of Unbreakable and is scaled based on the amount of damage you blocked with it."

These changes have made Unbreakable with Ursa Furiosa/Spirit of the Bear (Stoicism) have extremely high uptime when used correctly. Most optimally, your uptime should be 100% in higher difficulties where damage isn't exactly shying away from you. I would recommend this build on Prismatic Titan with a Spirit of the Bear class item. You could ultimately use any secondary perk you prefer, but I would heavily recommend Spirit of Synthoceps to fuel your melee generally for Knockout and Thunderclap as well as the other star of the show for this build: Vexcalibur. For the uninitiated, Vexcalibur is an exotic Void glaive that grants the wielder Void Overshields when blocking, and increases the wielders melee damage while an Overshield is active.

When I was initially theorycrafting this build, I thought that Vexcalibur and Unbreakable would be a redundant pairing; Too much overlap. I'd now say I had the wrong idea. They feed into each other pretty well. Unbreakable provides enough Overshields such that after you release the blast, you can get right to swinging with the glaive. It's a nice synergy to save a bit of that shield on Vexcalibur, seeing as it has such a low duration. Otherwise, the build is uncomplicated. Use Thunderclap for massive melee hits, Knockout to heal from your punches and Thunderclap, use your Rally Barricade to draw fire away from your face a bit. Simple.

I would say this build shines particularly well in higher difficulty activities where you're fighting a good amount of enemies: Grandmasters, Master Lost Sectors, Expert Exotic Missions just to name a few. It was a bit annoying in the Nether with all of the Grim present, but you can play around them, I'm just dumb. You could also definitely use it in Raid/Dungeon encounters where you need to fight a wealth of ads, but again Storms Keep is a hard ability to give up in those activities this Episode. The only areas I wouldn't recommend this build is actually in standard difficulty activities. This is because enemies are not nearly as aggressive or high damaging in things like Vanguard Ops for example, so it's much harder to justify even bringing such high survivability in the first place, let alone the difficulty charging up Unbreakable to keep the loop going.

That's all I have. Get out there, roll with the punches, and send 'em right back.
