PF2e Rune Extraction: When and Why
The math behind rune transfers. When to extract, when to sell, and how to stop wasting gold.
Published January 20, 2026 • 6 min read
Your fighter finds a +2 striking greatsword, but they use a longsword. Do you sell it? Transfer the runes? The answer depends on math most players never do. Let's fix that.
The Rune Economics Basics
In Pathfinder 2e, magic weapons and armor get their power from runes. When you find a magic sword, the value isn't in the sword—it's in the runes etched onto it.
Key Costs to Know
- Selling items: You get 50% of market value
- Rune transfer (etching): Costs 10% of rune value + requires a runestone
- Runestone: Costs 4gp (negligible)
- Extraction: The rune goes onto a runestone, destroying the original item
This means transferring a rune costs roughly 10% of its value, while selling the whole item nets you 50%. So why would you ever extract?
When Extraction Makes Sense
Extract When: You'll Use the Rune
If you find a +2 weapon and you currently have a +1 weapon, extracting the potency rune makes sense because:
Scenario: You have a +1 striking longsword, find a +2 greatsword
- • +2 Potency Rune value: 1,000 gp
- • Extraction + transfer cost: ~100 gp (10%)
- • Your cost to upgrade: 100 gp
- • Cost to buy +2 potency outright: 1,000 gp
You saved 900 gp by extracting instead of buying new.
Extract When: The Rune Is Expensive
Higher-level runes have higher value, making extraction proportionally cheaper compared to buying new.
| Rune | Value | Transfer Cost | Sell Value | You Save |
|---|---|---|---|---|
| +1 Potency | 35 gp | ~4 gp | 17.5 gp | 31 gp |
| +2 Potency | 1,000 gp | ~100 gp | 500 gp | 900 gp |
| +3 Potency | 16,500 gp | ~1,650 gp | 8,250 gp | 14,850 gp |
| Striking | 65 gp | ~7 gp | 32.5 gp | 58 gp |
| Greater Striking | 1,065 gp | ~107 gp | 532.5 gp | 958 gp |
| Major Striking | 31,065 gp | ~3,107 gp | 15,532 gp | 27,958 gp |
"You Save" = Rune Value − Transfer Cost (what you'd pay vs. buying new)
When to Just Sell the Item
Sell When: Nobody Needs the Rune
If your whole party already has +2 weapons and you find another +2 weapon, just sell it. You'll get 50% value immediately with no work.
Extraction only makes sense if someone will use the rune. A runestone sitting in your inventory forever was a waste of 10%.
Sell When: The Rune Is Low-Level
For cheap runes (+1 potency, basic striking), the savings from extraction are minimal. If you're level 10 with 5,000+ gold, saving 30 gp isn't worth the hassle.
At higher levels, just sell low-tier runed items unless someone specifically needs to upgrade from nothing.
Sell When: You Need Cash Now
Extraction requires finding a spellcaster with the right skills (usually in a settlement). If you're mid-dungeon and need to buy healing potions, sell first, optimize later.
Quick Decision Flowchart
Does someone in the party want this rune?
No → Sell the item
Is the rune worth more than 100 gp?
No → Probably just sell unless someone is starting from scratch
Can you access extraction services soon?
No → Sell now if you need the gold, otherwise hold
If yes to all above:
Extract the rune!
Property Runes: Same Logic, Higher Stakes
Property runes (flaming, frost, ghost touch, etc.) follow the same math but are often more valuable and more worth extracting.
Common Property Runes Worth Extracting
High Value (Always Extract if Useful):
- • Flaming/Frost/etc.: 500 gp
- • Greater versions: 3,000+ gp
- • Ghost Touch: 75 gp
- • Returning: 55 gp
Situational (Extract for the Right Build):
- • Wounding: 340 gp (great for rogues)
- • Disrupting: 150 gp (for undead campaigns)
- • Keen: 3,000 gp (crit-fishing builds)

TL;DR
Extract runes when someone will use them. Sell items when nobody needs the runes. The more valuable the rune, the more you save by extracting. Don't overthink low-level runes—the gold difference is too small to matter.
