You just found a unique with a purple number at the bottom. It says something about a "Weaver’s Will." If you're coming from other ARPGs, you might be looking for the Last Epoch weaver tree or a passive screen to click on. Stop looking. It doesn't exist—at least not in the way you think. There is no separate menu or skill tree where you spend points to upgrade these items. Instead, the "tree" is a hidden, semi-randomized progression system baked directly into the item itself while it sits in your inventory or on your character.
It’s honestly one of the coolest systems Eleventh Hour Games has implemented. It’s gambling, but without the gold sink. You basically become a witness to the item "growing" as you slaughter your way through Eterra.
The Mystery of the Last Epoch Weaver Tree
The confusion usually starts because people hear "tree" and think of the Passive Tree or the Skill Specialization windows. In Last Epoch, the Weaver’s Will system is a dynamic affix-generation mechanic. When you equip an item with Weaver's Will (WW), it has a set number of points—usually between 5 and 28. As you gain experience, the item "eats" that Will to do two things: add new affixes or upgrade existing ones up to Tier 7.
Think of it as a living organism.
It doesn’t just get stronger; it evolves. You might start with a pair of boots that have nothing but the base stats. Ten minutes into a Monolith run, you'll hear a distinct chime. Suddenly, those boots have Tier 3 Movement Speed. Another few minutes? Now they have Fire Resistance. It keeps going until the Weaver’s Will counter hits zero. Because these items can reach Tier 6 or Tier 7—levels usually reserved for Exalted items—a lucky Weaver's Will roll can actually outperform almost any Legendary you could craft in the Temporal Sanctum.
How the Item "Leveling" Actually Works
Experience is the fuel. But not just any experience. You need to be killing enemies that are close to your level or higher to see rapid progress. If you’re level 90 and running level 50 zones, your Weaver’s Will item is going to sleep. It won't budge.

There's a logic to the madness, though it feels chaotic.
The item follows a specific priority:
- If the item has fewer than four affixes, the "level up" has a high chance to sprout a completely new, random affix.
- If it already has four affixes, it will randomly pick one of those four and bump it up a tier.
- It can never go past Tier 7.
This is why players get obsessed with high "Will" counts. A piece of gear with 28 Weaver’s Will is a potential goldmine. It has enough "budget" to push multiple stats into that coveted purple Tier 7 range. However, if the item decides to roll "Reduced Bonus Damage from Crits" when you really needed "Health," you're stuck. You can’t use Chaos Glyphs on these. You can’t Forge them. You are purely at the mercy of the Weaver.
Why Some Items Are Better Than Others
Let’s talk about the items themselves. You’ve probably seen the Shattered Chains belt or the Cradle of the Erased shield. These aren't just random uniques; they are the foundation for some of the most broken builds in the current meta.
The Cradle of the Erased is a prime example. It’s a shield that gains Block Chance and Effectiveness every time you block, but it resets if you don't block recently. Now, imagine that shield "weaving" itself into having Tier 7 Health and Tier 7 Block Effectiveness. It becomes an impenetrable wall. Because the Last Epoch weaver tree logic allows for stats that shouldn't normally exist together on certain uniques, the power ceiling is astronomically high.
Compare this to the standard Legendary Potential (LP) system. With LP, you know exactly what you’re getting because you choose the Exalted item to smash into the Unique. With Weaver’s Will, you’re playing a long-form slot machine.
Is it frustrating? Sometimes.
Is it rewarding? When you hit a T7 level of a rare class-specific affix, absolutely.

Common Misconceptions and Where People Waste Time
One thing I see constantly in global chat is people asking if they can "reset" a bad Weaver roll. You can’t. If your Ambitions of an Erased ring rolls mana regeneration and minion damage for your Marksman, that ring is effectively bricked for that build. There is no "un-weaving."
Also, don't keep the item in your stash. It won't level up while sitting in your chest. It has to be equipped. This creates a weird tension where you might have to wear a slightly weaker item for a few Monoliths just to see if it turns into something god-tier. I usually recommend swapping to your Weaver gear during the "easy" parts of a run and switching back to your main gear for the boss if the item hasn't leveled up enough to be viable yet.
The Math Behind the "Will"
The "Will" number matters more than the item's base stats. A Relic of the Erased with 24 Will is almost always superior to one with 12, regardless of the initial rolls. Why? Because Tier 7 affixes require a lot of "points" to reach.

- A new affix costs 1 Will point to spawn at Tier 1.
- Upgrading an affix from T1 to T2 costs points.
- Upgrading from T6 to T7 is the "expensive" part of the hidden budget.
If you have a low Will count, the item will run out of gas before it reaches the powerful tiers. You'll end up with a mediocre unique with four Tier 3 stats. That's vendor food. You want those high rolls—18 and above—to really see the system shine.
Tips for Maximizing Your Weaver’s Will Drops
If you're hunting for these, you need to target-farm specific timelines in the Monolith of Fate. Since Weaver's Will items are Uniques, anything that boosts Unique drop rates helps.
- The Fall of the Outcasts timeline is great for early farming because of the "Unique or Set Accessory" rewards.
- Empowered Monoliths are mandatory. The higher the corruption, the better the chance for the "Will" count to roll higher. You're significantly more likely to find a 20+ Will item at 300 Corruption than at 100.
- Don't ignore the "Dying" or "Erased" prefixes in the item names. These are the markers that the item belongs to the Weaver category.
Actionable Steps for Your Next Session
Stop treating Weaver's Will items like standard gear. They are long-term projects.
- Check your Will count immediately: If it's under 10, it's probably not worth your time unless you're still in the leveling process (pre-level 50).
- Equip during Echoes: Put the item on and run a few high-density maps. Listen for the "ding."
- Evaluate at Tier 4: Once an item has four affixes, look at them. If three of the four are useless for your build, stop. Don't waste the XP. Take it off and save it for an alt character or trade it if you're in the Merchant's Guild.
- Push Corruption: If you want those T7 procs, you need to be in Empowered Monoliths. The scaling of Weaver's Will seems to correlate with the area level and the inherent "luck" of the drop.
The Last Epoch weaver tree is essentially a story the item tells as you play. Some stories end in tragedy (Health Regen on a Ward build), but the ones that end in glory define your entire endgame experience. Keep an eye on those purple numbers; they are the difference between a "good" character and a "broken" one.
