Breach: the Genesis Tree & caster jewellery

How Breach works

An Unstable Breach is a tear that opens for a short time. Killing the Breach monsters that pour out extends the timer (a progress bar shows the time left and how much each kill adds). Reach 100% and the Breach stabilises, spawning a tougher challenge at its centre, including Vruun, Marshal of Xesht. Run over Clasped Hands for extra item drops. Killing Breach monsters drops Hiveblood, Wombgifts and Breachstone Splinters.

A Breach Hive is a tear grown out of control: with a blessing from Chayula you burn to its centre and defend Ailith while she destroys it (if Ailith dies, the Hive remains). Collecting Splinters into a Breachstone opens a Breach Domain on the Atlas containing Hives, Sky Hives and Fortresses. The Fortress bosses It That Was Tul and It That Was Esh drop the key to the pinnacle Xesht, We That Are One (4 difficulties). Xesht drops the caster chase uniques: Hand of Wisdom and Action, Choir of the Storm, The Pandemonius.

The Genesis Tree (why casters farm Breach)

The crafting hub at the Monastery of the Keepers. Feed Hiveblood and Wombgifts into its wombs to grow gear; allocate its own passive nodes to steer what you birth. The four Wombgifts:

Signet

Rings

Ornate

Amulets

Banded

Belts

Lavish

Currency

It crafts 6 exclusive Ring, 4 Amulet and 4 Belt base types, plus a new set of Caster and Minion modifiers that only exist on Genesis Tree rings and belts. Full stacks of Splinters become a Revelatory Wombgift, turned in for a Breachstone.

The 12 Catalysts now come only from the Genesis Tree (they no longer drop from monsters). Each adds quality enhancing one modifier family on a ring or amulet: Flesh (Life), Neural (Mana), Sibilant (Caster, ~1 div), Xoph's (Fire), Tul's (Cold), Esh's (Lightning), Chayula's (Chaos), and more. A Breach Ring can take up to +50% quality from Catalysts (around 170 Life), making it one of the strongest rings in the game. A separate set of 12 Catalysts adds quality modifiers to Jewels.

The full Breach Atlas subtree

Exact node text from poe2db. Points come from Otherworldly Books of Knowledge (2 each) and Xesht kills at higher difficulty. Small nodes make the Twisted Domain harder but more rewarding.

• Wombgift Quantity and Hiveblood Quantity: +5% each (small nodes, ×8 each).
• Breeding Program: +100% chance to find your selected Wombgift type (Lavish / Ornate / Banded / Signet).
• Moment of Risk: Wombgifts have 5% chance to drop one level higher per Explicit Modifier on the map (juice the waystone), plus 2 extra Rares per Stabilised Breach.

• Growing Wealth: +5 Genesis points for the Currency Womb. Exquisite Design: +5 for the Amulet Womb. Diverse Control: +2 for every Womb.
• Essence Transference: Essences near Breaches / Hives have 20% chance to gain an Essence of the Breach.

• Shape the Chains (multichoice): +30% Rare Breach monster effectiveness (-20% pack), or +20% effectiveness (+15% pack).
• Reality Wound: Unstable Breaches take 10 extra seconds to collapse (more kills, more loot).
• Frantic Invasion: Unstable Breaches 100% increased chance to contain Vruun. Study the Chains: Vruun 50% increased chance to drop Lineage Supports.
• Reactive Hiveseeding (needs a Breach Stronghold revealed): completing Breaches has a 10% chance to add a Hive to a nearby map.
• Tear Open the Rift (pinnacle): revealing Breach Strongholds adds Modifiers to revealed maps; consume an extra Breachstone to add mods to all of them.

Juicing: exact tablet text

Breach Tablets add an Otherworldly Breach; the suffixes (poe2db) tune density and rewards:

• of the Domain: +15-30% Quantity of Breach Splinters. of the Form: +30-60% Quantity of Wombgifts.
• of the Horde: +40-70% Magic Monsters / +5-15% Pack Size. of the Hand: +5-20% Rare Breach effectiveness.
• of Fissuring / of Rupturing: chance for +1 / +3 additional Breaches.
• of the Flash: +Pack Size and Breaches open/close 10-30% faster (better for high clear speed).
• of the Flesh: Wombgifts 10-30% chance to drop one level higher. Unique Wraeclast Besieged: +2-5 Hiveborn waves, +Rares on Stabilise (but reduced Pack Size).

The farming loop

1. Atlas: Wombgift + Hiveblood Quantity, Breeding Program (pick your Womb), Genesis point nodes, then density (Reality Wound, Shape the Chains) and Frantic Invasion for Vruun.
2. Tablets: 2-3 Breach tablets rolled for of the Domain (splinters) + of the Form (Wombgifts) + density. Add 1 Ritual tablet to revive the packs.
3. In map: clear fast to keep Breaches open, grab every Clasped Hand, stabilise for Vruun and his Lineage Supports.
4. At the Genesis Tree: spend Hiveblood + Wombgifts to birth caster rings / amulets / belts and Catalysts. Catalyse Breach Rings to +50% quality.
5. Bank Splinters into Breachstones for Xesht runs (uniques + Atlas points at higher difficulty).

• Breach Splinters and Breachstones in bulk.
• Catalysts (Sibilant / Flesh / Neural are always in demand) and finished Genesis Tree caster rings / amulets.
• Xesht uniques (Hand of Wisdom and Action, Choir of the Storm, The Pandemonius) and Vruun's Lineage Supports.
