The new Graft system sits at the center of Keepers of the Flame. The Genesis Tree is a separate passive network you feed and shape. You place wombgifts into the tree and spend Graftblood to grow rewards. The tree does not directly buff your character. The tree changes what items and currencies it produces for graft crafting PoE 1 Currency.

Graftblood is the main resource you must collect. You earn Graftblood by clearing the special breach and Breach-like encounters that the league adds. You bring that blood to the Genesis Tree to trigger births from wombgifts and to charge production. You need a steady stream of Graftblood if you want a reliable crafting loop.

Grafts are the objects you make with this system. Grafts are new, temporary item slots that attach to your character and can grant strong passives or active effects. You can eventually equip multiple grafts, and the best grafts can change how your build behaves. The graft items and their modifiers are separate from standard gear crafting and have their own item types and rules.

Foulborn currencies are the special orbs the Genesis Tree can produce. These currencies behave like warped versions of regular orbs but are tuned for grafts. The tree can birth Foulborn Augments, Regals, and even Foulborn Exalted equivalents that skew rolls toward higher level modifiers. Because these currencies are meant for grafts, they give more predictable, high-end results than ordinary orbs when used on graft items.

To be efficient you must treat the system like a production line: specialize the Genesis Tree and farm the right currency. First, pick the graft types and modifiers that matter for your build and then commit points to tree nodes that raise the chance to birth the specific currency or graft types you want. Second, focus on farming the encounters that drop the highest Graftblood per run so you keep production steady. Third, use Foulborn currency selectively on grafts that match your plan so you avoid wasting rare items on speculative rolls.

Remember that this system sits beside the normal economy of PoE 1. Currency like Chaos and Exalted Orbs still matter for your broader goals, but Foulborn items give a deterministic path to high-tier graft results when the Genesis Tree is tuned correctly. Keep reserves of u4gm PoE 1 Currency for map upkeep, trading, and bench crafting that support your grafting runs. Use standard currency to smooth parts of your progression while you build a self-sustaining graft pipeline.

Track which nodes produce the most useful outputs and adjust your tree slowly rather than spreading points thin. That steady, targeted approach turns grafting from random luck into a reliable method of powering up your character.
