As I mentioned, the main focus of the build is to have an incredibly large health pool (see video for demo) by generating as much ward as possible with Leaf Barrier. Let me first explain the mechanics of that specific interaction and how we make use of it, and then explain how we manage to build damage on the build.
Ward Generation
Leaf Barrier gives you Ward equals to your armor each time you enter Spriggan Form. This means that we want to scale this ability in 3 ways:
- Have as much Armor as possible
- Have as much Ward Retention as possible
- Enter Spriggan Form as frequently as possible
Let's start with number 1. We scale Armor's effectiveness with %Armor, Strength and miscellaneous nodes like Thicket of Thorns 5/5. (Strength only scales our melee damage and we already get an additive %armor increase from it, so don't worry about too many of those affixes on your gear.) The last item which improves our Armor that we aim to get is Throne of Ambition. The main source of our Armor then comes from Thorn Shield. It is further scaled in effectiveness with all the nodes we invest in on the Spriggan Form tree (see tree below). Because Thorn Shield is a spell that has to be cast, we further scale our Armor/Ward by increasing our Cast Speed.
When it comes to our Ward, PrefixIntelligence provides 4% Ward Retention per point. As a Primalist we get little else from it. Ward Retention can further be found on items like the Opulent Focus. The main source of our Ward Retention comes from using Frostbite Shackles which allows us to scale our Ward Retention with our Cold Resistance.
When it comes to number 3, the obvious answer is to have as much SuffixIncreased Cooldown Recovery Speed and PrefixIncreased Cooldown Recovery Speed While Transformed as we can get on our gear. This is crafted on our Boots and Belt and then Helmet respectively. We also use Ancestral Garb and Opal Ring. This reduces the cooldown of our transform abilities to 3-3.5 seconds. Which means we use Leaf Barrier every 6-7 seconds.
The next piece of the puzzle is Roar of the Woodland which gives +4 seconds to all stacks of Thorn Shield on us when entering Werebear Form. This allows us to keep a higher number of Thorn Shield stacks on ourselves at a given time, which translate into Ward when we enter Spriggan Form again.
This basically dictates the main tempo and rotation of our build: every 3.5 seconds we shift between Werebear Form and Spriggan Form.
It's also worth noting that aside from our raw health pool, we also have 83-85% damage mitigation from armor and fairly high damage over time reduction with the right items as well as consistent cleanse.
Dealing Damage
First let me describe how we build our non-reflect damage, as if you rely on thorn damage alone you will do virtually no damage to bosses.
The main problem with making this build work is finding a way to deal (non-reflect) damage. This is because we spend half the time of our rotation in Spriggan Form, and all we do in that form is cast Thorn Shield which is very hard to scale damage on, as almost all of our points on the Spriggan Form tree go into building Armor. Therefore to make this build do damage you need a way to deal damage both in Werebear Form and Spriggan Form. The best way I found to do that is with a combination of Cold DoTs, ailments like Frostbite (which can also be applied with Thorn Shield) and spell damage.
Frostbite Shackles gives us a chance to apply Frostbite on hit. The Druid Passive Tree also holds additional ways to scale Frostbite and Cold damage like River Spirits 5/7 and Piercing Gale 6/8. We use Werebear Form's Crackling Assault 5/5 as the main form of applying Frostbite and other Ailments. We also take Wisened Claws on the Werebear tree to increase our spell damage while in Werebear Form.
Maelstrom is the main source of our damage, and because we want to have high Attunement—which I'll get to why when talking about Reflect Damage—we can scale its damage by a decent amount by speccing into Turbulence 5/5 once we have at least 60 Attunement. The way we generate Maelstrom is with Warcry and Whirlpool 4/4 which is going to be cast 2-3 times each cycle of our 7 second rotation (depending on whether or not you have Shallow Breath 1/1). We also take Power of the Storm 1/1 which gives us another passive way to cast lightning bolts around us that apply ailments. Maelstrom also provides Frenzy and Haste.
Warcry gives us additional cold damage, a way to apply Chill and a way to Cleanse ourselves of Ailments with Purging Shout 1/1 while in Werebear Form.
Break Yourself Upon My Body (Reflect Damage)
OK, and now to the most fun and silly part of the build.
Last Epoch has a few ways to build reflect damage, but in reality there is only one way that is actually effective at doing so. Which is using the unique shield Thornshell. Thornshell doesn't provide a lot of flat reflect damage, instead it multiplies all of your base reflect damage by 5-9% for each point of Attunement you have. So at, let's say 60 Attunement, with a max roll Thornshell, your flat reflect damage does 540% more damage. This is why I told you before that you want to have fairly high Attunement.
By itself that wouldn't benefit us all that much, except that because we already try to get as many stacks of Thorn Shield at once as we can, and because we have access to Briar Shell 5/5 on the Spriggan Form tree, this build already specializes at stacking flat reflect damage. When fully geared and with 60+ Attunement, monsters that hit you can take 30-40K damage per hit. All you have to do is stand in place and watch as every monster that hits you goes poof as it vanishes from existence.
The limitation of reflect damage, obviously, is that enemies actually have to hit you. This means that certain enemy types, like bosses and some monsters that mostly use damage over time, cannot be consistently damaged with thorns.
A note on Reflect Damage: it is considered an independent type of damage and is calculated separately. Therefore it cannot be increased by general %damage modifiers unless directly specified, like in the case of Thornshell.
Optional 5th Skill
When it comes to your 5th skill you have a couple of options.
Summon Storm Crows is what I recommend you use when beginning to gear up. The Crows provide you extra Ward Retention from Ornithology 5/5 (80% with 2 Crows). They can also act as Ward generators with the use of Goodberries and Silverberries if you choose to go Low Life with the build, which is an option at the beginning when you're just starting to run Monoliths. If you are choosing to go Low Life(ish), get Last Steps of the Living from Formosus ASAP (50% drop rate). We only take Berserker 5/5 if using Last Steps' together with Exsanguinous. Otherwise we can't stay at <35% health.
The problem with Storm Crows at higher difficulties is that they die too often, take too much of an investment and aren't as good as the other options once we have enough Ward Retention going.
Eterra's Blessing is what I do recommend you use as your 5th skill. Rosebloom makes Eterra's Blessing cast with each cast of Thorn Shield. Purge is amazing for us as it solves many of our damage over time and ailment problems. Ancestral Renewal 1/3 makes it so that your Healing Totem is summoned automatically (which provides you cast speed). And Safeguard 5/5 gives us additional Ward Retention and Poison Resistance.
How to Play
As I mentioned, the gameplay involves a 7 second rotation:
- When you enter Spriggan Form you cast Thorn Shield on yourself* nonstop until the cooldown of Werebear Form is up
- When Werebear Form is up, you transform
- Upon entering Werebear Form you use Rampage** nonstop until the cooldown of Spriggan Form is up again
- When Spriggan Form is up, you transform and start the rotation again
* Make sure to keep your cursor away from your Healing Totems so that Thorn Shield is not cast on them instead of you! Also, if using Eterra's Blessing Healing Totem is summoned automatically.
** Roar is used automatically in this build. You may want to wait for the 3rd Roar while in Werebear Form before transforming into Spriggan Form to prioritize damage over ward.
