Greavard is one of the most memorable Ghost-type Pokémon introduced in recent generations, and many players are eager to know how its evolution works in Pokémon Legends Z-A. While the game brings new systems and twists compared to classic titles, evolving Greavard still follows a clear set of rules once you understand the mechanics. This guide explains everything you need to know in simple terms, so you can evolve Greavard efficiently without confusion or wasted time.

Greavard is a Ghost-type Pokémon known for carrying a candle on its head that slowly burns away its life energy. In Legends Z-A, Greavard fits perfectly into the darker lore and exploration-focused gameplay. You can usually find Greavard in quiet, eerie zones, often appearing during nighttime or in abandoned areas.
Before focusing on evolution, it is important to understand how Legends Z-A handles progression. Unlike traditional Pokémon games, evolution conditions often rely on behavior, time, and environment rather than just leveling up. This design encourages players to interact with the world instead of grinding battles endlessly.
Greavard’s Evolution Requirement
In Pokémon Legends Z-A, Greavard evolves into Houndstone, its final evolutionary form. The core requirement remains tied to leveling up, but with a specific condition attached. Greavard must level up during nighttime within the game world.
This means simply reaching the required level is not enough. If Greavard levels up during the day, the evolution will not trigger. You must be mindful of the in-game clock and plan your battles accordingly.
Key points to remember include:
- Greavard must level up at night
- The evolution only triggers during a nighttime level-up
- Daytime leveling will not work
This small detail is where most players make mistakes, so timing is critical.
How to Check Nighttime in Legends Z-A
Legends Z-A features a dynamic day and night cycle. The environment lighting, sky color, and Pokémon spawns change depending on the time. Nighttime is usually marked by darker skies, visible stars, and an increase in Ghost-type encounters.
If you are unsure whether it is night, return to camp or use rest mechanics to adjust the time. Choosing to rest until night is the safest way to ensure your Greavard evolves when it levels up.
Fast Ways to Level Up Greavard at Night
Once nighttime begins, your goal should be to gain experience quickly without accidentally switching to daytime. The best strategies include controlled battles and experience planning.
Effective methods include:
- Battling higher-level wild Pokémon nearby
- Using experience-boosting items if available
- Completing nighttime research tasks and side objectives
Avoid long travel sequences that may push the game clock forward unexpectedly. Staying in one area helps maintain the nighttime window.
What Happens After Evolution
When Greavard evolves, it becomes Houndstone, a Ghost-type Pokémon with higher stats and improved battle potential. Houndstone gains access to stronger moves and better survivability, making it far more useful in both exploration and combat scenarios.
Houndstone is especially effective in battles that reward status effects, endurance, and tactical positioning. Its presence also unlocks new Pokédex research tasks, contributing to overall completion progress.
Common Mistakes Players Should Avoid
Many players struggle with Greavard’s evolution due to small but important errors. Understanding these mistakes can save you time.
The most common issues include:
- Leveling up Greavard during the day by accident
- Forgetting to monitor the in-game time
- Switching party members and missing the level-up moment
Always double-check that Greavard is in your active party and close to leveling up before initiating nighttime battles.
