In Diablo IV Season 7, a new gameplay feature called “mystic gems” has been added to the game. This system allows players to enhance their skills by embedding different gems, especially wizard skills (known as “witchcraft” in the game), which will become stronger.If you’re new to the game or not very familiar with it, this article will explain in simple terms how to obtain these gems, what they do, and how to combine them for the best results.
1. How do I get Arcane Gems?
To obtain these gems, you need to complete a quest called “Whisper Bounty.” During the quest, you will encounter some special enemies. After defeating them, you will have a chance to drop a material called “Escaped Skull.” You can then take these materials to an NPC named “Grena,” who lives near the “Whisper Tree.”
Once you find her, you can use the following items to synthesize Mystic Gems:
- Escaped Skull
- Restless Corruption (also dropped by monsters)
- Gem Fragments
Sometimes you may need to exchange existing Mystical Gems for new ones, so it is recommended that you do not sell your old gems.

2. What are the basic bonuses of each gem?
Regardless of the type of Mystical Gem, they all provide two basic attributes:
- Increases armor by 160 points (making you more resistant to damage)
- Increases all elemental resistances by 8% (e.g., fire, ice, electricity, etc.)
In addition to these defensive enhancements, the most important aspect is how they enhance your skills. As long as you embed the right gems into your equipment, your skills will become more powerful!
3. Specific effects of Mystic Gems
Below, I will explain each of the currently available mystical gems, their effects, and which classes or playstyles they are suitable for.
1. Unholy Pact
This gem is suitable for players who like to use unholy skills. It increases the power of all non-unique unholy skills by 25%. In other words, the power of your normal unholy skills will be increased.
2. Soul Heart
Similar to the above, but this is for intelligence-based skills. Equipping this gem will increase the power of your intelligence skills by 25%.
3. Toad’s Wish
This gem is for those who prefer the growth and decay playstyle. It increases the power of your skills in this category by 35%, which is more than the previous two gems.
4. Phantom Thread
If you like to control enemies with curses and then deal suppression damage, this gem is perfect for you. When you attack enemies affected by curses, suppression damage increases by 40%.
5. Elder’s Mark
Another gem for the curse-based playstyle. When you activate a potential skill, if the target is already under the effect of a curse, the damage dealt increases by 25%, and you are more likely to trigger potential skills.
6. Death Wind
When you have three or more unholy skills equipped, your movement speed increases by 25% and your critical strike chance increases by 15%. Suitable for characters who need to move quickly or attack rapidly.

7. Witchcraft Moment
Also requires three or more evil skills. Every 15 seconds, your core skill will become an evil tag, allowing you to benefit from other evil bonuses. Very useful.
8. Secret Art of Anger
If you like to use unique skills, this gem will increase the damage of your unique witchcraft skills by 40%. Suitable for players who prefer high-end playstyles.
9. Voice of the Stars
As long as you have the Spirit state, your ultimate skill will gain the Grimoire tag and deal 10% additional damage. Suitable for use with Spirit builds.
10. Mind’s Eye
When you use three or more Intelligence skills, the cooldown of your Defense, Trap, and Death skills is reduced by 20%. Suitable for players who rely on skill frequency.
11. Spiral Coin
Also requires three Spirit-based skills, extends the duration of crowd control effects by 30%, and increases the chance of triggering lucky effects by 20%. Suitable for control-oriented characters.
12. Horn of Abundance
When using the Growth and Decay playstyle and equipping three or more related skills, Barrier, Resilience, and Thorn damage are increased by 30%.
13. Vulture’s Claw
While in Spirit state, your sustained damage output speed increases by 50%. Suitable for DOT (sustained damage) playstyles.
14. Sharp Finger
Summoned creatures deal 25% more damage to elite monsters affected by curses. Suitable for summoners.
15. Evil Amulet
When you use a skill with the Summoning tag and take lethal damage, you generate a shield equal to 100% of your maximum health. This effect can only trigger once every 75 seconds, but it can save your life in critical moments!
16. Marsh Friend
When you have three or more Growth and Decay skills, your primary attributes and maximum health increase by 10%, and you become immune to control effects. This is extremely useful.
17. Moonlight Barrier
For each unique witchcraft skill level equipped, you gain 3% damage reduction and 1% maximum elemental resistance. The higher the level, the better.
18. Dust Stone
When enemies have a spirit or curse effect, your damage against them increases by 4% each time. The more layers, the stronger.
19. Hungry Void
When you have a spirit state, every 8 seconds, enemies around you will be pulled to you. Very suitable for group battles.
4. How to choose arcane gems?
Everyone plays differently, so choose gems based on how you like to play.For example, if you like to control enemies and fight slowly, Phantom Thread and Dust Stone are good choices; if you like quick bursts, Death Wind and Rage Secret Art might be more suitable for you.
In addition, some gems require certain conditions to take effect, such as having three skills of the same type equipped. So when equipping gems, pay attention to the overall configuration and don’t just look at the strength of individual gems.
5. Summary
In summary, the Mystic Gems system is a highly engaging new feature that allows players to freely customize their skill combinations based on personal preferences, creating truly unique characters. While it may seem complex at first, understanding the function of each gem and combining them with your playstyle will make it easy to master.
Hopefully, this easy-to-understand article has helped you better understand the Mystic Gem system in Diablo IV Season 7. Go give it a try and create your own ultimate character!
