The Crucible forge is the mechanic added in the Crucible league that allows you to unlock and level up skill trees on a weapon or shield (or El'Abin's VisageEl'Abin's Visage

To use it, you must select a weapon or shield in your equipment slot (main or swap) or the top and left-most identified weapon or shield in your inventory slot. Once selected, you can hold the button to begin channeling to the Crucible. The longer you channel, the more enemies it spawns and more damage and damage reduction they receive. A bar near the circle will fill up, indicating the amount of experience points that will be contributed towards unlocking the selected node in the item's Crucible Passive Skill Tree. A charge percentage and difficulty will also be displayed at the bottom.

You are given a few seconds after channeling before the Crucible spawns enemies, in case you were interrupted and want to channel further. Leaving the circle around the Crucible will force spawn the enemies. Charging the Crucible to 100% will also spawn the enemies.

Once most of the enemies are defeated (all the Rare/Unique monsters and most normal/magic monsters), the item will receive experience points towards its Crucible Passive 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.

Tree limitations

Weapons trees usually have offensive nodes.

Shields trees have defensive nodes.

In each tree only one node at each tier can be unlocked.

The number, type, and potency of nodes depends on the item's item level.

Passives tend to have an archetype, chosen between Fire, Cold, Lightning, Physical, Chaos, or Elemental. This also reflects the types and skills of monsters spawned.

Version history

Version	Changes
3.21.0c	Added an indicator to the Crucible Forge user interface which displays the relative difficulty for the amount of channelling you have done, and how close you are to fully-channelling the encounter. Disabled most of the lower-tier Crucible Passives that have downsides on the initial skill from rolling. Initial skills with downsides are far less common and can generally only roll in the endgame. When an initial skill does come with a downside, the upside should outweigh the downside. The Crucible Passive that granted Weapon Elemental Damage and cannot Inflict Elemental Ailments can no longer roll. Unique Items obtained by selling an item with a Crucible Passive Tree now come with their own Crucible Passive Tree, with the first skill allocated. Crucible Passive Tree Skills that cause the item to sell for an additional Unique Item can no longer be transferred onto other unrelated Base Types by combining Crucible Passive Trees. Updated the explode visuals for the Crucible Passive Tree skill that causes Totems to Explode on Death to be more appropriate.
3.21.0b	Crucible monsters now have much less damage reduction, except when channeled to maximum difficulty. Crucible monsters now have less life at all levels, most notably in Part 2 of the campaign, and in low-tier Maps. In addition, Crucible Bosses have had their life further reduced by roughly 20%. Increased the amount of Crucible Passive Skill Tree experience gained from encounters, particularly for encounters that are not fully-channelled. This should result in smoother progression on the experience bar while channelling. Increased the drop rate of Igneous GeodesIgneous GeodeDark as obsidian with a red-hot core, the geode hums with mysterious energy.Right click on this item to open it.. Lower-tier Crucible monsters are now more likely to drop these. Note Geodes have a higher chance to drop in high-tier Maps, and their drop chance is affected by item quantity.
