Harvest Crafting Explained: Tag Reforges, Lifeforce and What's Left
Harvest no longer has the old 'reforge keeping prefixes' or 'remove' crafts. What it does have (tag-guaranteed reforges, more/less-likely reforges and resistance swaps) is still some of the most targeted crafting in the game.
In this guide
A lot of Harvest advice online still describes crafts that were removed years ago, like "reforge keeping prefixes" or "remove a fire mod". If a guide tells you to use those, it's out of date. Harvest today is smaller, but what's left is still some of the most targeted crafting in Path of Exile.
Pick a base for the finished result
A Harvest tag guarantee does not bypass base, influence or item-level restrictions. Choose the retained item for all planned tiers first: commonly 86 for endgame body armour or 35%-movement-speed boots, often 85 for eligible suppression gloves. A cheap donor minimum serves a different purpose. See choosing crafting bases.
In this Crusader chest discussion, Physical reforging is one option for explode while defence prefixes are another part of the goal. Highest normal explode starts at 85; top natural body-armour percentage defence needs 86 in the modifier data. Harvest can roll other physical modifiers instead of explode. Set the exact target, not “any physical mod”, if explode is what you need.
How Harvest works now
Harvest monsters in the Sacred Grove drop Lifeforce: Vivid (yellow), Primal (blue), Wild (purple), with Sacred Lifeforce from the boss Oshabi. Spend it at the Horticrafting Station in your hideout, choosing from its available recipes.
Since the 3.19 rework, you store and trade Lifeforce, not individual crafts harvested from plots. Recipes have different costs; check the station before buying materials.
The crafts worth knowing
Tag reforges roll a rare item with new random modifiers, including a modifier of the selected type. The guarantee is a tag, not an exact modifier, tier or set of good companion mods. The available choices and costs are shown in the station.
More/less-likely reforges bias modifier types; they do not preserve your existing modifiers. Older guides quoting the stronger “much more likely” craft describe an earlier version.
Resistance swaps change an eligible elemental resistance modifier to another element. Read the recipe and check crafted, hybrid and influenced modifiers before spending.
Add/remove crafts are separate expensive recipes with restrictions, including restrictions on influenced items. They are not the same as a tag reforge. Inspect the exact recipe before using one.
Removed in 3.29: the Synthesise craft and the socket-colour craft that turned a socket white. Ordinary non-unique synthesised crafting bases are no longer obtainable in the current league; the exception is a corrupted unique becoming rare, which does not supply a normal editable base. Existing Standard items are a separate case. Do not buy Lifeforce for an old synthesised-base recipe. GGG's 3.29 notes document these changes.
The workflow
- Choose a base whose existing non-fractured mods you are willing to lose.
- Pick a reforge whose guaranteed tag includes your target modifier.
- Reforge, inspect the complete result and repeat within a fixed Lifeforce budget.
A reforge replaces existing explicit mods. A good essence start is not automatically preserved. A compatible prefix/suffix lock can protect one side, but the lock may be consumed and must be reapplied. Check metamod interactions before using a valuable base.
Two accessible starting crafts
Chaos-resistance rings
Start with an ordinary non-influenced Amethyst or Two-Stone Ring. Chaos reforge targets the natural chaos-resistance family on this pool; it does not guarantee its best tier or good companion mods. Ilvl 81 unlocks the top natural chaos-resistance tier. Ilvl 84 is useful if you also want top elemental-resistance tiers: those are different thresholds, not a requirement for T1 chaos resistance. Check the ring modifier data before buying bases.
Set a keepable chaos-resistance tier plus life or useful elemental resistance as your stop condition. A ring with the desired suffixes and an open prefix can take a life bench craft; inspect the complete result before spending more Lifeforce. Price comparable rings with the same useful combination, rather than assuming every T1 resistance hit sells.
Elemental-attack Stygian Vises
On an ordinary non-influenced Stygian Vise, increased Elemental Damage with Attack Skills is the natural Attack-tagged modifier family. An Attack reforge therefore targets that family, but still rolls its tier and the other affixes. Ilvl 86 unlocks the highest natural tier; the current modifier data lists that threshold. Influenced belts can add competing Attack mods, so do not reuse the guarantee on a different pool.
Keep results with useful life, resistances or an open finishing slot; a lone damage prefix is not a finished belt. Compare Lifeforce and base costs with equivalent listed belts in your league. Set a total attempt budget before batching; neither example promises profit.
A worked example: the explode chest
The explode-on-kill mod on Crusader body armour has the physical tag. So instead of a blind Chaos reroll, you can use the Physical tag reforge. Every attempt then guarantees a physical-tagged mod, and explode is one of them. The explode chest guide walks through it.
Automating Harvest with Exiled Bench
The app's Harvest page has three craft types:
- Mods. The reforge loop above. Under Calibration → Horticrafting, align the bench frame and save the item slot and Craft button together. Select the intended recipe in game, then roll a Single item or your whole Inventory: each item is moved into the craft window, reforged until your Target mods land (at your tier or better), and moved back out. If you pause or stop, the item is returned safely.
- Div card reroll. Rerolls a divination card stack via Harvest.
- Currency reforge. Feed a stack of fossils, oils, catalysts, delirium orbs, essences or timeless emblems through Harvest's reforge until it turns into something worth keeping. You tick which ones you're happy to feed. Anything unticked is a keeper, so is anything the app doesn't recognise, and prices come live from poe.ninja. Each run ends with what went in and what came out, in chaos. If your Lifeforce runs out, it stops and says so.
Tips
- Compare the actual mod pool. A tag guarantee still has competing modifiers and tiers.
- Protect valuable affixes deliberately. Essences, fossils and Harvest reforges are alternatives for starting a base; chaining them does not automatically keep earlier hits.
- Count Lifeforce as a cost. Use current trade prices, including the material spent on failed attempts. A potentially valuable output is not guaranteed profit.

How to Craft an Explode Chest in PoE 3.29 (and Elevated Explode)
The Crusader body-armour mod that makes enemies explode on kill is a clear-speed staple. Here are the realistic ways to land it, the imprint + Orb of Dominance route to elevated explode, and which parts to automate.
Choose a Crafting Base: Item Level, Donors and Finished Gear
A donor that can roll one mod is not automatically a good endgame base. Choose item level, defence type, implicit and fracture for the complete craft.
Double-Influenced Tailwind Boots: Onslaught, CDR or Spectres
Choose an Onslaught, cooldown or Raise Spectre donor for Tailwind boots. Follow the elevated Onslaught route through the merge, Elusive and movement speed.
Spend fewer clicks on preparation
Roll one base or a stash tab, including Regal and capped Exalt stages. Set your targets and limits; inspect the result at your chosen checkpoint.
