What is the Undine Jar?

The Undine Jar is a special event item used during the Undine Evolution update in Catch a Monster. Its main purpose is to summon special Undine-related monsters inside the event area. These summons can give players access to rare pets, evolution materials, and event progression rewards. The jar works similarly to Void Jars, but it is specifically tied to the Undine event and its exclusive monster pool.

How to Get Undine Jars

Currently, players can obtain Undine Jars from several sources during the event.

• Event Tasks The easiest method is completing event missions and daily objectives. Tasks may include: Playing for a certain amount of time, Defeating event monsters, Clearing dungeons, Enhancing pets, & Killing bosses! These missions often reward players with Undine Jars directly.
• Boss Rewards The new Lampyr boss on Circus Island also has a chance to help progress event rewards tied to jars and event materials. Boss farming is currently one of the best methods for active players.
• Event Progression Rewards Some event milestones and achievement systems also provide jars as rewards after reaching certain requirements. This makes consistent grinding more important than pure luck.

How to Use the Undine Jar

Using the jar is simple.

1. Open your inventory
2. Find the Undine Jar
3. Use the item inside the event area
4. A special summon encounter will appear

The summoned monster may vary depending on current event rates and boosts. Some players recommend saving jars until luck boosts or admin events become active since spawn quality may improve during boosted periods.

The Undine Jar is easily one of the most valuable event items currently available in Catch a Monster. Whether you are farming evolutions, chasing Void pets, or trying to get stronger event monsters, the jar plays a huge role in progression. Right now, the smartest strategy is probably balancing both approaches: use some jars for immediate progress while saving the rest for future boost events. That way, you can continue evolving your team without missing out on potentially better rewards later in the event.
