POE 1 News: T0 Gigabuffs & Day 12 Teasers in Path of Exile

Two Unique Item Buffs That Landed in 3.28 Mirage
Patch 3.28 Mirage launched on March 6, 2026, and among its long list of balance changes were buffs to two unique items that had been sitting on the bench: Essentia Sanguis, a lightning-focused Vaal Claw, and Bino's Kitchen Knife, the poison dagger. Neither is a headline chase unique, but both got a real upgrade that changes how they slot into a build.
This breakdown covers exactly what 3.28 changed on each item, with the before-and-after numbers from the official patch notes, and where the two now sit relative to the rest of Path of Exile's unique pool.
Key Takeaways
- Patch 3.28 Mirage launched March 6, 2026, and buffed both Essentia Sanguis and Bino's Kitchen Knife.
- Essentia Sanguis now adds 1 to 650-850 Lightning Damage, raised from 1 to 600-700.
- Essentia Sanguis grants +200-300 maximum Energy Shield, up from +30-40, and doubles maximum recovery per Energy Shield leech.
- Essentia Sanguis lost its chance to block attack damage while dual wielding claws, a trade-off for the offensive gains.
- Bino's Kitchen Knife spreads poison to enemies within 3 metres on a poisoned kill, up from 1.5 metres, which doubles the radius and roughly quadruples the covered area.
- Bino's Kitchen Knife also raised chaos resistance to +17-27% and ally life regeneration to 400 per second.
One item is an offence-and-defence rework, the other is a clear-speed tool. Here is each change in detail.
Essentia Sanguis: The Lightning Claw Buff
Essentia Sanguis is a unique Vaal Claw built around lightning damage and Energy Shield leech, and it had drifted out of relevance before 3.28. The Mirage patch gave it three concrete changes.
- Added lightning damage rose to 1 to 650-850, from 1 to 600-700. The floor is unchanged, but the top end of the roll is meaningfully higher.
- Maximum Energy Shield jumped to +200-300, from a near-token +30-40. For an Energy-Shield-leech claw, that is the change that actually matters.
- Maximum recovery per Energy Shield leech is now doubled, which lets the claw refill a larger Energy Shield pool faster in sustained fights.
The buff is not free. Essentia Sanguis lost its chance to block attack damage while dual wielding claws, so a build that leaned on it for a layer of block needs to find that defence elsewhere. On balance it is a stronger item than it was, but it asks for a slightly different build around it.
📌 Common mistake: Treating Essentia Sanguis as a finished chase item. Even after the 3.28 buff it is a mid-tier claw that suits a transitional Energy Shield build; plan to replace it with a crafted rare once your build matures, rather than over-investing in it.
Bino's Kitchen Knife: The Poison Proliferation Buff
Bino's Kitchen Knife is a long-standing unique dagger on the Slaughter Knife base, and 3.28 turned it into a genuine clear-speed pick for poison builds. The headline change is its on-kill poison spread.
Before 3.28, killing a poisoned enemy spread poison to other enemies within 1.5 metres. Mirage doubled that to 3 metres. Because the covered area scales with the square of the radius, a doubled radius covers roughly four times the ground, so poison chains across a screen far more reliably than it used to.
- Poison spread radius: 3 metres on a poisoned kill, up from 1.5 metres.
- Chaos resistance: +17-27%, roughly double the old +8-12% roll.
- Ally life regeneration: 400 per second, up from 200.
The result is a dagger that clears maps quickly through poison proliferation. Single-target damage is not where Bino's shines, so a pure boss-killing build still wants a different weapon, but for mapping and crowd clear it is now a defensible main-hand choice.
Where These Buffs Sit Among PoE's Chase Uniques
Path of Exile players use the term "T0", short for tier-0, for the rarest chase uniques: items like Mageblood, Headhunter, and Kalandra's Touch that can anchor an entire character's economy. Those items are vanishingly rare and trade for enormous sums.
Essentia Sanguis and Bino's Kitchen Knife are not in that bracket, and the 3.28 buffs do not move them into it. Both are accessible mid-tier uniques that most players can pick up cheaply early in a league. What the Mirage patch did was make each one worth slotting again in the build it was designed for, rather than skipping it on the way to a crafted rare. Players who want to grab either one for a Mirage character can pick up these buffed uniques without farming the drop themselves.
That is the practical takeaway: 3.28 did not create two new chase items, it revived two old ones. If you are building lightning Energy Shield leech or a poison mapper this league, both are back on the table.
3.28 Mirage Item Buffs at a Glance
Here is the short version of every change covered above, with the direction and the practical effect on a build:
| Item | 3.28 change | Build effect |
|---|---|---|
| Essentia Sanguis | Lightning damage to 1-650/850; max Energy Shield to +200-300; ES leech recovery doubled | Stronger transitional pick for lightning Energy Shield leech builds |
| Essentia Sanguis | Lost block chance while dual wielding claws | Build must source block or defence elsewhere |
| Bino's Kitchen Knife | Poison spread radius 1.5 m to 3 m on a poisoned kill | Far stronger map clear through poison proliferation |
| Bino's Kitchen Knife | Chaos resistance to +17-27%; ally regen to 400/sec | Better personal defence and party utility |
With both items broken down, a few questions tend to come up from players weighing them for a Mirage build.
Frequently Asked Questions
What is the current Path of Exile league?
The current Path of Exile 1 league is 3.28 Mirage, which launched on March 6, 2026. It is a league of the original Path of Exile, separate from Path of Exile 2. The name is sometimes miswritten as the "mirror league", but Mirror refers to the Mirror of Kalandra currency, not the league.
Was Bino's Kitchen Knife buffed in 3.28?
Yes. Patch 3.28 Mirage doubled the on-kill poison spread radius of Bino's Kitchen Knife from 1.5 metres to 3 metres, raised its chaos resistance to +17-27%, and doubled the nearby-ally life regeneration to 400 per second. It is a stronger map-clear weapon for poison builds than it was before the patch.
Is Essentia Sanguis worth using in 3.28 Mirage?
Essentia Sanguis is worth using as a transitional weapon for lightning Energy Shield leech builds. The 3.28 buff raised its added lightning damage to 1-650/850 and its maximum Energy Shield to +200-300, and doubled its Energy Shield leech recovery. It is a mid-tier claw, not a chase item, so most builds eventually replace it with a crafted rare.
What did Essentia Sanguis lose in the 3.28 buff?
Essentia Sanguis lost its chance to block attack damage while dual wielding claws. The 3.28 patch traded that defensive line for higher lightning damage and a much larger maximum Energy Shield roll, so builds that relied on the claw for block now need another source of defence.
What does "T0" mean in Path of Exile?
"T0" is community shorthand for tier-0 uniques, the rarest chase items in Path of Exile. Mageblood, Headhunter, and Kalandra's Touch are the usual examples. Essentia Sanguis and Bino's Kitchen Knife are not T0 items; they are accessible mid-tier uniques that the 3.28 buffs made worth using again.
Do I need a new copy of these uniques to get the 3.28 buffs?
Any copy of Essentia Sanguis or Bino's Kitchen Knife that drops in the 3.28 Mirage league rolls with the new values. Copies that have been sitting in standing storage from older leagues may keep their old stat lines, so a fresh drop or trade in Mirage is the reliable way to get the buffed version.
