Crucible Passive Skill Tree

This article describes new Path of Exile content released in version 3.21.0. Information may be missing or incorrect.

Please expand this article so that it provides complete and accurate information.

A Crucible Passive Skill Tree appears on weapons and shields that have been used in a Crucible Forge. After gathering enough experience from the Forge to unlock the first node, the item generates a random Passive Skill Tree that grants the item additional modifiers. An item can have up to five depths in its tree, and only one node can be allocated for each depth.

Overview

An example of a Crucible Passive Skill Tree

When an item gains a Crucible Passive Skill Tree, it will have a randomized set of passives based on the item type. It can have 2 to 5 columns (depth) of passives, most passives have tiers of potency, and not all nodes will be connected. The available passive skills and their tiers, amount of experience required, and maximum possible depth are based on item level.

The Crucible Forge can only generate a Crucible Passive Skill Tree on non-unique items. Unique items can be given a Crucible Passive Skill Tree using a Furnace in the Forge of the Titans that grants one to a unique item.

Completing a Crucible Forge encounter is required to allocate points into the tree.

This removes all experience points that went toward the passive. The item's Crucible Passive Tree will remain the same, even if you deallocate all passives.

Primeval Remnants contain a forge that lets you sacrifice a non-unique item to merge its Crucible Passive Skill Tree into another item with the same base type. The forge in Primordial Remnants allow you merge two copies of the same unique item or corrupted non-unique items. The Forge of the Titans may also have a Furnace that adds a Crucible Passive Skill Tree to a unique item or removes one from a non-unique item.

Mechanics

If an item with a Crucible Passive Skill Tree is used in a vendor recipe that returns the same base item, it will keep its original tree.

When an item with a Crucible Passive Skill Tree is Split, both copies of the item will have the same tree. Experience and allocated nodes are also retained.

If an item had its Crucible Passive Skill Tree removed, it will generate a new one the next time it gains a Passive Tree.

Merging

When two Crucible Passive Skill Trees are merged, it generates a new tree based on both items' Passive Trees. The game uses certain logic to determine odds of specific nodes and connections (bridges) it generates.

• For each two nodes in the same position, the new tree will pick one or the other.
• If both trees have a node in that position, there is a chance for the passive in that position to mutate, causing it to upgrade or downgrade a tier or turn into a completely different node, which can potentially transform into a merge-exclusive passive.
• An allocated passive is more likely to appear in the new tree. For nodes in the same position, an allocated node has a higher chance of appearing over the unallocated node.
• If one tree has a passive in a certain position but the other doesn't, there's a high chance it will gain a passive in that spot from the tree that contained a node. The merged tree will never generate a node where neither trees had a node in that position.
• A node spawns bridges to its preceding nodes that can possibly lead up to it. If there's only one possible path going backwards, it's guaranteed to generate a bridge there. If there are two possible paths leading back, there is a roughly even chance it will generate a bridge for only the upper node, only the lower node, or both.
• If both trees have two of the same passives (disregarding tiers) of the same depth but in in different positions, it can generate that passive in either position. If this happens, one of the nodes that wasn't chosen may be treated as an empty node.
