Concept
This build isn't great for T16 and if you have other setups such as GoD DH or Multishot available, you should go with those instead.

In Torment 16 we want to go fast, so this setup differs from the GR versions. We include Danetta's Hatred, turning our Vault Action Shot into a spender that can detonate Spike Trap while we move. For this, we need to switch its rune to Echoing Blast. Omryn's Chain creates Caltrops automatically to make enemies fly to us whenever we detonate traps.

Gameplay
Keep up your buffs Shadow Power, Preparation Focused Mind and Vengeance as much as possible. Vault around to hunt elites and valuable monster packs. Whenever you engage in combat, drop a few Spike Traps around the area and detonate them with Vault.

Whenever you have enough leftover Discipline, spam Smoke Screen Displacement for extra speed.

Setups
If you need more damage, replace Wreath of Lightning with Zei's Stone of Vengeance.

If you don't feel tanky enough, replace Hot Pursuit with Awareness and Warzechian Armguards with Trag'Oul Coils to free up the armor cube slot for Goldwrap.

In groups, replace Warzechian Armguards with Nemesis Bracers to spawn elites from shrines and pylons.

Concept
This setup is similar to the solo push version described in the main sections of the guide, but aims to complete GRs in faster runs lasting around 3 minutes. Reduce the set-up time in favor of more damage output and don't worry about Convention of Elements rotations. In addition, Bane of the Stricken isn't necessary so that gem gets replaced by Molten Wildebeest's Gizzard to protect the buff from Squirt's Necklace.

To increase run speed, we use Shadow Power Shadow Glide and drop Numbing Traps for Tactical Advantage.

Gameplay
Keep up the buffs from Vengeance and Shadow Power while searching valuable monster packs and elites. When you find some, place a few Spike Traps around the area, then tap Caltrops + Evasive Fire simultaneously to pull them in.

Once you have set up a pull, place Caltrops in the center and spread 5x Spike Trap around the area, then detonate them with 1 tap of Strafe for maximum damage output. Repeat this until all enemies are dealt with and move on. Activate Smoke Screen whenever necessary to reduce incoming damage.

Setups
At higher Paragon (2,500 or more), Guardian's Jeopardy should be replaced by Captain Crimson's Trimmings for more damage, cooldown and resources.

If you have too much trouble keeping up the Squirt's Necklace buff or staying alive, replace Molten Wildebeest's Gizzard for Bane of the Powerful and Numbing Traps or Ambush for Awareness.

Concept
This is the setup is similar to the one described in main sections of the guide but more optimized for group play in high GRs. Most of the hard work is done by your Supports and instead you simply focus on dealing the most damage. With party buffs, the setup is significantly tankier.

Instead of pulling enemies around yourself, coordinate with your team to deal heavy bursts during the Fire Convention of Elements cycle. In order to play this setup with Vengeance on a 48sec cycle, you need to have at least 47% Cooldown Reduction.

Gameplay
Keep up Shadow Power whenever enemies are present. Wait for your supports to prepare a pull, then start cycling 5x Spike Trap + 1 tap of Evasive Fire to deal damage. While doing so, make sure to protect yourself with Smoke Screen as much as possible.

Optimally, prepare the pull and 10 Spike Traps right before the Fire Convention of Elements cycle. This way you can detonate them immediately when the cycle changes and repeat the process two more times for the highest damage output. Every 48 seconds, activate Vengeance at the start of the Fire Convention of Elements cycle to have it up for 2 out of 3 rotations.

Once the density thins out, move on to find new enemies and prepare the next pull with your team. Whenever Oculus Rings appear, reposition into them for more damage and use Smoke Screen frequently to stay alive.

Setups
At lower Paragon (2,500 or less), Captain Crimson's Trimmings should be replaced by Guardian's Jeopardy.

If you want to include Awareness in the setup, drop Numbing Traps for it.

A more high-end version of the build replaces Natalya's Slayer with Dawn and drops Endless Walk for Natalya's Reflection + Squirt's Necklace. Like this you don't have to worry about standing still for extra damage and have permanent Vengeance uptime, but now have to protect the Squirt's Necklace buff with the shield from Molten Wildebeest's Gizzard. This setup is recommended if you are at the point where you speed run high tier GRs in only a few minutes. However, if you can't keep up the amulet's buff most of the time, you should stick the the regular setup.

If you're playing in a team as the only damage dealer or for some other reason have to kill the boss, include Bane of the Stricken instead of Pain Enhancer.
