Volt Evolution Event Explained

The main event of this update is the Volt Evolution Event. Players must complete daily tasks to earn rewards. There are 14 available tasks each day, and completing them unlocks special event items. Event rewards include:
- Complete 10 tasks: Amethyst Fragment
- Complete all 14 tasks: New Event Egg
The event sounds simple on paper, but some tasks may take significant time and effort, especially for newer players. If you are unable to finish all 14 tasks, aiming for at least 10 tasks daily is still a good strategy to collect valuable resources.
New MechaVolt Evolutions
One of the biggest additions in Update 0.34 is the new evolution line for MechaVolt. The monster now has:
- Two regular evolutions
- One secret evolution
The secret evolution is currently the most desirable version because of its rarity and power.
How to Get Secret MechaVolt Evolution
To unlock the secret evolution, you’ll need:
- 12 Scythes
- 15 Ice Gems
- 15 Grass Gems
Scythes are obtained from the new Scare Reaper boss. After collecting all required materials, players can attempt the evolution recipe. The secret evolution has roughly a 22% chance of success, which is noticeably better than some previous secret evolution rates in the game. Because of the low success chance, expect to farm multiple attempts if luck is not on your side.
New Scare Reaper Boss Guide
The latest boss added to Specter’s Shallows is Scare Reaper.
This boss is designed for stronger players and comes with an enormous health pool exceeding 500 billion HP. Players should bring their highest damage monsters and prepare for a lengthy fight if their team is not fully upgraded.
Scare Reaper is also important because it drops materials required for MechaVolt’s secret evolution.
Boss Rewards
Scare Reaper can drop:
- Scythes
- Boss Egg
The Boss Egg contains a chance to hatch Scare Reaper.
Void Scare Reaper Chance
Players opening the Boss Egg have approximately:
- 1.5% chance to obtain Void Scare Reaper
This makes the Void version one of the rarer monsters currently available in the game.
New Pet Collection Quest
Another addition in Update 0.34 is a new collection quest available through the Pet Master located on Skyheart Isle. This collection focuses on the Tideland monster set.
Completing the collection grants:
- +8% Attack Buff
An 8% attack increase may not sound huge at first, but it can significantly improve overall damage when fighting bosses and clearing difficult content. Players who have been ignoring collection quests may want to start working on them because these permanent bonuses can add up over time.
Dungeon Improvements
Dungeons received several welcome improvements in this update. Changes include:
- Faster dungeon completion times
- Reduced prices for Potential Serums
- Reduced prices for Arcane Spark Stones
- Reduced prices for Scavenger Cores
These adjustments make farming resources much more efficient and reduce the grind needed for progression.
Mutation System Changes
Wild monsters can now mutate when captured. This means players farming monsters or leaving the game running while AFK have more opportunities to obtain mutated creatures without relying entirely on previous methods. Mutated monsters remain valuable because they can be used for crafting and other progression systems.
Enhancement System Buffs
The enhancement system also received a useful upgrade. Update 0.34 introduces an enhancement pity system for players attempting to reach +10 enhancements. This should reduce frustration and make upgrading monsters more consistent over time. Combined with the improved secret evolution rates, progression feels a little more forgiving than before.
Catch a Monster Update 0.34 focuses more on progression improvements than massive content additions. The new Scare Reaper boss and MechaVolt evolutions are the highlights, while dungeon improvements, cheaper upgrade materials, mutation changes, and enhancement pity systems make daily gameplay smoother.
Players looking for the strongest rewards should prioritize farming Scare Reaper, collecting Scythes for the secret MechaVolt evolution, and completing as many Volt Evolution Event tasks as possible. While some players may feel the update could have offered more content, it still introduces several useful changes that make progression easier and more rewarding in the long run.
