Purrchena drops into Talos-II as Endfield’s first true welfare 5-star, and the clock on her materials starts the moment you claim her. If you wait until the Purry Big Feline! RAWR! event hands her over, you will already be behind on Protodisks, Boletes, and the rare growths every other operator also eats. This Arknights Endfield Purrchena material guide exists so you can walk into Version 1.5 with a stockpile instead of a shopping list.
And one more thing. Consider topping up Arknights Endfield through Enjoygm if you want extra Sanity Boosters and Protocol Pass resources without paying full store price. The extra daily Sanity turns Protocol Space runs into a reliable pipeline for the exact Arknights Endfield operator upgrade materials Purrchena will demand the second she joins your roster.
Who Purrchena Is and Why Her Materials Matter Right Now
Purrchena is a 5-star Physical Defender who uses a Sword. She arrives free alongside her signature weapon Dessert Moment through the limited giveaway event Purry Big Feline! RAWR! (starting September 24). Event missions also give enough tokens to push both her Potential and the weapon’s refinement to max without extra pulls. Since Purrchena is welfare, every Endministrator will own her; the difference between a useful teammate and a bench-warmer is how fast you feed her Arknights Endfield character materials.
Purrchena’s kit is built around Protection, anti-interrupt, Giftbox heals, Nature Infliction on recast, and random bombs or pulls from her Ultimate. That kit scales with level, promotions, and skill ranks the same way every other operator does. The materials themselves are not unique to Purrchena—they are the shared operator upgrade materials pool but the volume you need for a complete 90/90/9/9/9 Defender is still substantial.
Arknights Endfield Purrchena Promotion Materials (Level Caps)
Every operator, including Purrchena, hits hard level caps at 20, 40, 60, and 80. Crossing each cap requires Protodisks or Protosets plus a specific Rare Growth mushroom and T-Creds.
And here is an overview of the promotion materials she is going to need in the gameplay:
| Promotion | Level Cap Unlocked | Protodisk / Protoset | Rare Growth | T-Creds |
| I | 40 | 8 Protodisk | 3 Pink Bolete | 1,600 |
| II | 60 | 25 Protodisk | 5 Red Bolete | 6,500 |
| III | 80 | 24 Protoset | 5 Ruby Bolete | 18,000 |
| IV | 90 | 36 Protoset | 8 Bloodcap + 20 rare progression item* | 100,000 |
The rare progression item at Promotion IV is typically Metadiastima Photoemission Tube or D96 Steel Sample 4 depending on the operator’s exact requirement. Confirm in-game once Purrchena is live and the quantity stays 20.
Also make sure to farm Protodisks and Protosets in Protocol Space: Promotions near the Core AIC Area. Higher difficulties mix both items. Pink Bolete appears in early Valley IV and starter hubs. Red Bolete is concentrated in Originium Lodespring. Ruby Bolete and Bloodcap sit in later Wuling and high-tier collection nodes.
Operator EXP Materials for Purrchena
Leveling from 1 to 60 uses Combat Records. From 60 onward you switch to Cognitive Carriers. Rarity only changes how much EXP each item grants.
Best early-to-mid farm method is Valley Pass Sub-PAC on Difficulty 4. The same node also drops a usable mix of both EXP types. Later you can let the Manufacturing Cabin on Dijiang produce them passively while you run other content.
Approximate EXP totals you will need here as Arknights Endfield Purrchena materials are:
- To 20: ~23,000 EXP
- To 40: ~272,000 EXP
- To 60: ~747,000 EXP
- To 80: ~1,212,000 EXP
- To 90: ~1,792,000 EXP
Make sure to stockpile both Combat Records and Cognitive Carriers now; Purrchena will eat the same pile every other new operator uses.
Skill Leveling and Mastery Materials
Skills 1–9 consume Protoprism and Protohedron plus T-Creds for Arknights Endfield Purrchena. Mastery ranks (M1–M3) add rare plants (Kalkodendra, Chrysodendra, Vitrodendra) and later gold-tier items.
Farm Protoprism and Protohedron in Protocol Space: Skills, also located near the Core AIC Area. The plant materials drop from specific overworld nodes and high-tier Protocol Spaces. Because Purrchena’s Battle Skill, Combo, and Ultimate all want investment for Protection uptime and Giftbox frequency, plan to take at least her Battle Skill and Ultimate to rank 9.
Dessert Moment Weapon Materials
Purrchena’s free signature sword follows the standard weapon tuning track:
| Tuning Cap | Cast Die / Heavy Cast Die | Rare Ore |
| 20 → 40 | 5 Cast Die | 3 Kalkonyx |
| 40 → 60 | 18 Cast Die | 5 Auronyx |
| 60 → 80 | 20 Heavy Cast Die | 5 Umbronyx |
| 80 → 90 | 80 Heavy Cast Die | 8 Wulingstone |
Cast Die and Heavy Cast Die come from Protocol Space: Weapon Tune near the Originium Byproduct Processing Center. Kalkonyx and higher ores are world-collectibles in Valley IV and Wuling. Because the event also gives refinement materials, you can push Dessert Moment to high potential without extra gacha, but you still need the tuning mats listed above.
Where to Farm Arknights Endfield Operator Upgrade Materials Efficiently
You can prioritize these nodes in order:
- Protocol Space: Promotions (Core AIC Area) — Protodisks and Protosets.
- Protocol Space: Skills (Core AIC Area) — Protoprism and Protohedron.
- Protocol Space: Weapon Tune — Cast Die family.
- Valley Pass Sub-PAC Difficulty 4 — Combat Records and Cognitive Carriers.
- Originium Lodespring — Red Bolete and several mid-tier growths.
- Mines Cable Car Station / Power Plateau — D96 Steel Sample 4 and Metadiastima Photoemission Tube for late promotions.
- Event shops and AIC Quota Exchange — limited extra Protodisks when you have spare tokens.
Sanity is the real spot here. A Monthly Pass plus occasional Sanity Boosters lets you clear more Protocol Space runs per day. If you want those resources without paying official store rates, Enjoygm remains a practical option for discounted Origeometry and pass packs that convert directly into extra farming time for Purrchena’s character materials.
For the full Version 1.5 event calendar, banner dates, and how the Purry Big Feline! RAWR! missions line up with Typhoeus’s debut, you can check through our Arknights Endfield Version 1.5 preview write-up that breaks down the same patch window this material plan is built around: Arknights Endfield Version 1.5 Preview. Pair that overview with the tables above and you will know exactly which materials to pre-farm before September 24.
Conclusion
Purrchena is free. The materials that make her actually protect your Typhoeus or Yvonne teams are not. So, use our Arknights Endfield Purrchena materials guide to see what makes the best impact on her from now on. And then start the farms today and she will be ready the same week you claim her.
