Build Requirements

This build has several Legendary Aspects that are required before it will function properly. The Legendary Aspects you will need the following at a minimum to make the build work at its most basic level. These Aspects are all non-codex, which means you will need to find them on a Legendary Item then imprint them onto specific gear. We also use two Uniques in this build as shown below, Fleshrender is required and the Mad Wolf’s Glee is an optional chioce.

Boons – The Druid Specialization

Boons are additional buffs provided to the Druid class as part of their specialization. To unlock your Boons, you will need to complete a simple quest on the west side of the map in the stronghold of “Tur Dulra”. This becomes available at Level 15 and should be completed as soon as possible. The Boon mechanic allows you to pick a single buff from each of the corresponding master animals and the addition of a second Boon buff from a chosen master animal you select.

Once you are in the endgame and have completed the skill tree from the previous section, utilize the following set of Boons for the best results.

Build Mechanics and Playstyle

The playstyle for this build is a brawling style of combat. We will start by activating Grizzly RageGrizzly Rage which is going to activate our Caged Heart of Inexorable ForceCaged Heart of Inexorable Force. This will pull all of the surrounding mobs on top of us, allowing us to start poisoning them with RabiesRabies. Once you have used Rabies, continue attacking with your ClawClaw and start to cycle your Roars, Blood HowlBlood Howl and Debilitating RoarDebilitating Roar.

Both of these Roars are going to trigger the special effect from our Unique weapon FleshrenderFleshrender. This unique effect triggers an explosion around the player, damaging any Poisoned enemies with the damage value from the weapon. This damage can be a Critical Strike and will benefit from the Critical Strike Damaging stacking buff that we get from our Grizzly RageGrizzly Rage and Aspect of the Rampaging WerebeastAspect of the Rampaging Werebeast. This is where the majority of our power to clear out packs of mobs comes from.

The other half of our damage in this build comes from our ShredShred ability. This is used in combination with Aspect of the Blurred BeastAspect of the Blurred Beast to launch a powerful strike against elites and bosses. This means you will need to continually be stacking Poisons on your enemies to keep up both damage components. This can be challenging to manage at first, but will become easier over time. The second Unique used in this build is Mad Wolf's GleeMad Wolf’s Glee, which will boost our ClawClaw and Shred ranks for more power.

Now that you understand the skill rotation and the brawling style of attacking, we will look close at some other elements of the build that you must master.


While this build is very simple to jump in and play, the challenging component comes from being able to keep enemies Poisoned. This is why the build is designed with four primary methods to Poison, listed below:

  • ClawClaw – Adding Fierce ClawFierce Claw to this ability lets us Poison with each strike.
  • ShredShred – Adding Raging ShredRaging Shred allows our third strike to Poison an enemy.
  • RabiesRabies – this is our best method of spreading our Poisons out to all enemies due to the ability for the Poison to spread naturally with this skill. We also include Natural RabiesNatural Rabies, to accelerate that process.
  • Toxic ClawsToxic Claws – any Critical Strike we make against an enemy will Poison them.

These methods are what will help keep our Poisons stacked on our enemies so we can use our two defensive skills or ‘Roars’ to trigger the AoE from our Unique item: FleshrenderFleshrender. Overall, this build performs well as long as you keep your poison stacks up – failing to do so and you will see a significant drop off in damage.

Gear Choice and Stat Priority

As you begin to farm in World Tier 3 and 4, Rare and Legendary item drops will begin to appear with some regularity depending on your luck. We recommend saving the targeted Legendary items that have the needed Legendary aspects listed below. We also recommended to keep multiple copies of the build’s Aspects in your Stash for future upgrades.

As for the Rare items, you will need to inspect each one for targeted affixes for use in each specific slot and do your best to match the recommended rolls. We have listed our targeted affixes in order of importance. Check the chart below and make note of what affixes you are searching for when you see a Rare gear piece drop.

Please note that these affixes are the recommended picks for the Roaring Fleshrender build, but that is simply our opinion. Other affixes could certainly work instead of the ones listed above, but may not be optimal. Also, there are several very specific affixes that are required to make the build work, they are as follows:

A final point on acquiring the right Legendary Aspects, use your Obols to target farm them. Obols are awarded from many different activities in the game, you will always stockpiling them until you hit your maximum. Instead of just randomly spending them on a random pick, use them to target what you might be missing from this build. It is a great way to target a specific slot of loot and find what you need.

Below you will find the optimal setup for Legendary Aspects for the Twisted K-9 build. Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the slot it was posted with.

Listed below are all the best-in-slot Aspects found on Legendary items that are important for the Roaring Fleshrender Druid build. Aspects from the Codex of Power can be used if you cannot find the proper Legendary drops, but they have weaker effects.
