A comprehensive guide to maximizing your Yamask and Galarian Yamask catches during Pokemon Go’s October Research Day event.
Event Overview & Halloween Theme
Pokemon Go’s October festivities continue with a spooky Research Day spotlighting the Ghost-type Pokemon, Yamask, and its regional Galarian counterpart.
Niantic has officially unveiled the details for this limited-time event, providing trainers a focused opportunity to capture both Yamask and Galarian Yamask. This event is the key to obtaining their evolved forms, Cofagrigus and Runerigus, for your Pokedex.
October in Pokemon Go is a month-long celebration of Halloween, featuring events like the Gastly, Duskull, and Litwick Spotlight Hours and the multi-part Halloween event. The Yamask Research Day fits perfectly within this eerie seasonal theme.
This guide will cover all essential event details, including the boosted wild encounters, new avatar cosmetics, and strategic advice to help you optimize your three-hour window for maximum candy and shiny hauls.
Event Date, Time & Core Mechanics
Mark your calendars: the Yamask and Galarian Yamask Research Day is scheduled for Saturday, October 19, 2024, from 2:00 PM to 5:00 PM local time. This three-hour window is your only chance to access the event’s exclusive Field Research.
The core gameplay loop involves spinning the Photo Discs at PokeStops and Gyms. This action will grant you special event-themed Field Research tasks. Completing these simple tasks rewards you with an encounter with either Yamask or Galarian Yamask.
Pro Tip: Focus on areas with high PokeStop density. Having more stops within walking distance allows you to cycle through tasks faster, discarding any that are too time-consuming (like “Make 3 Excellent Throws”) in favor of quick ones (like “Catch 5 Pokemon”). This maximizes your number of guaranteed Yamask encounters.
Critically, encounters from these Field Research tasks have a significantly increased chance of being Shiny compared to standard wild encounters. This makes task completion the most efficient shiny hunting method for this event.
Wild Encounters & Spawn Strategy
Alongside the research tasks, the event will feature increased wild spawns of various Pokemon. While the specific species list wasn’t detailed in the announcement, past Research Days typically boost spawns related to the theme—expect other Ghost-types or Pokemon fitting the Halloween aesthetic.
A major bonus is that all these wild Pokemon will also have the potential to be Shiny, assuming their shiny form is released in the game. This turns the entire map into a potential shiny hunting ground.
Common Mistake to Avoid: Don’t get distracted by common wild spawns. Your primary focus should be completing Field Research tasks for the guaranteed Yamask encounters with better shiny odds. Check wild spawns as you walk between stops, but do not linger unless it’s a rare Pokemon you need.
Optimization Tip for Advanced Players: Use Incense and a Star Piece during the event. Incense will attract additional Pokemon to your location as you walk, increasing your overall catch count and stardust. A Star Piece will multiply the stardust you earn from every catch and research reward, making the event highly efficient for resource gathering.
Yamask & Galarian Yamask Stats
During the Research Day, the Combat Power (CP) range for encountered Yamask and Galarian Yamask will be adjusted for the event. While the exact values were not listed, they typically fall within a standard range for such limited-time encounters, making them easier to catch than their wild counterparts.
The primary goal for most trainers will be evolution. Both Yamask and Galarian Yamask require 50 Candy each to evolve into Cofagrigus and Runerigus, respectively. There is no special evolution item or requirement beyond the candy cost.
Candy Farming Strategy: Use Pinap Berries on every Yamask you catch, especially if it’s not shiny. This doubles the candy reward from 3 to 6 per catch. If you have a Yamask or Galarian Yamask as your Buddy Pokemon during the event, you can also earn extra candy from walking. Transfer any low-CP, non-shiny specimens after the event to Professor Willow for one additional candy each.
Paid Timed Research Analysis
An optional Paid Timed Research ticket will be available for purchase. This special research story will cost US$2.00 (or local equivalent) and provide additional Field Research-style tasks that yield more encounters with Yamask and Galarian Yamask.
The shiny rate for Pokemon encountered through this Paid Timed Research is identical to the shiny rate for the free Field Research tasks. It does not offer improved odds, only additional encounter opportunities.
Critical Deadline: Like all Timed Research, you must complete all steps and claim the rewards before the event concludes at 5:00 PM local time on October 19. Unclaimed rewards are lost forever.
Value Assessment: For casual players or those on a budget, the free event offers more than enough chances to get the Pokemon and candy needed. The Paid Research is best suited for dedicated shiny hunters who want to maximize their number of rolls on the shiny random number generator, or for players who may have limited mobility and fewer PokeStops available to them.
Avatar Items & Customization
To celebrate the event, two new avatar items will debut in the in-game shop: the Festival Mask (Pikachu) and the Festival Mask (Eevee). These festive, Halloween-themed masks will be available for purchase starting October 14, 2024, five days before the Research Day itself.
- Festival Mask (Pikachu)
- Festival Mask (Eevee)
These are likely cosmetic items purchased with PokéCoins. They allow you to customize your trainer’s appearance but provide no gameplay advantages. If you enjoy collecting avatar gear, mark your calendar for their early release.
Advanced Player Strategies & Common Pitfalls
Pre-Event Preparation:
- Stock Up: Ensure you have 100+ Poké Balls, 30+ Pinap Berries, and enough space for items and Pokemon.
- Scout Locations: Identify an area with a high density of PokeStops (like a downtown park or mall) the day before.
- Set Buddy: If you have one, set a Yamask or Galarian Yamask as your buddy to earn candy while walking.
During the Event:
- Priority Order: 1) Spin new stops for tasks. 2) Complete quick tasks. 3) Catch rewarded Yamask (use Pinap). 4) Check nearby wild spawns.
- Resource Management: Use Pinap Berries on all non-shiny Yamask. Use regular Razz Berries or Nanab Berries only if you are struggling to catch a shiny.
- Time Management: Don’t spend more than a minute on any single catch or animation. Speed is key.
Common Pitfall: Wasting time trying to perfect excellent throws on every encounter. During a time-limited event, consistent great throws that secure the catch are more valuable than missing an excellent throw attempt. Focus on speed and reliability.
Final Verdict & Action Plan
The Yamask and Galarian Yamask Research Day is absolutely worth participating in for any trainer. Free events that offer guaranteed encounters with otherwise elusive Pokemon, boosted shiny rates, and a clear path to filling your Pokedex are the best value Pokemon Go provides.
The Paid Timed Research is a luxury, not a necessity. Only purchase it if you are a completionist or have specific goals that require an extreme number of encounters. The free experience is robust and rewarding on its own.
By following the strategies outlined above—focusing on task efficiency, using berries wisely, and preparing your inventory—you can transform this three-hour event into a major step toward completing your Ghost-type collection and earning powerful evolutions.
