Crucible Passive Skill Tree

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

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 maximum possible depth is 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.

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. Primordial Remnants allow you to merge the trees of the same unique items and also works with corrupted 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 recipes 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.

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. There is also a chance for the passive to mutate into an entirely different node, causing it to upgrade or downgrade a tier or turn into a merge-exclusive passive.
• An allocated passive is more likely to appear in the new tree in the same position than a passive that is unallocated.
• 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.
• Bridges are based on previous nodes the passive can make a connection to. If there is only one possible adjacent node in the previous tier, it's guaranteed to generate a bridge there. If there are two possible adjacent nodes, there is a roughly even chance it will generate a bridge for only the first node, only the second node, or both.
