In Monster Hunter Now, Mysterious Driftstone V can give your armor one of four skills: Critical Range Boost, Ice Attack, Charge Master or Partbreaker. Featured large monsters and elder dragons guarantee the stone during the Halloween Driftsmelting Bonanza, which starts October 26 at 9 AM local time and ends November 8 at 11:59 PM. Driftstones you obtain during the event need only 1 km of walking to smelt. As of the latest update, I found no source that confirms the Driftgem V shard exchange cost or a best armor to smelt.

What Mysterious Driftstone V Is
Driftstones are items that add skills to your gear through driftsmelting. A Mysterious Driftstone is a special version that appears during Driftsmelting Bonanza events and offers a limited set of event skills. The “V” marks this edition.
| Item | Detail |
|---|---|
| Event | Halloween Driftsmelting Bonanza |
| Part I | Starts October 26, 9 AM local time |
| Part II | Starts November 2, 9 AM local time |
| Event ends | November 8, 11:59 PM local time |
| Exchange hubs | Halloween 2026 hubs stay open until November 15 |
| Skills | Critical Range Boost, Ice Attack, Charge Master, Partbreaker |
| Smelting distance | 1 km for event-obtained stones |
I found these event details in one third-party article. I could not locate the official Monster Hunter Now announcement for this event, so check the in-game news before you plan around the exact times.
Mysterious Driftstone V Skill List
The stone can give your armor one of four skills. The article does not publish individual odds for each skill, so I cannot tell you which is most common.
| Item | Detail |
|---|---|
| Critical Range Boost | One of the four possible skills |
| Ice Attack | One of the four possible skills |
| Charge Master | One of the four possible skills |
| Partbreaker | One of the four possible skills |
I did not find skill descriptions for this event’s list. Therefore, tap the stone in game to read each skill’s text before you smelt. Official event pages from earlier months, such as August 2026, did describe their skills in detail, so the same screen should show you this one.
How to Get Mysterious Driftstone V
During the event, hunting the right monsters guarantees the stone. Here is how the drops work.
- Featured large monsters: they guarantee Mysterious Driftstone V.
- Featured elder dragons: they also guarantee it.
- Non-featured large monsters: they guarantee one of the standard colors instead. These are Crimson, Azure, Amber, Cyan, Pale and Black Driftstones.
So the key is to pick featured targets. Here are the lineups.
| Item | Detail |
|---|---|
| Part I | Aurora Somnacanth, Black Diablos, Somnacanth, Legiana, Stygian Zinogre, Espinas, Brute Tigrex, Bazelgeuse |
| Part II | Aurora Somnacanth, Black Diablos, Azure Rathalos, Glavenus, Brachydios, Viper Tobi-Kadachi, Kulu-Ya-Ku, Deviljho |
The same article also lists Velkhana as an elder dragon expected to appear more often at Interception points. Meanwhile, Aurora Somnacanth and Black Diablos appear in both parts, so you get two chances at them.
The 1 km Driftsmelting Bonus
Driftstones you obtain during the Halloween event have a reduced smelting distance of 1 km. The article says this applies to stones you obtain during the event, not to stones you collected before it. Because normal driftstones list longer distances, the bonus saves real walking.
Here is what that means in practice:
- Hunt featured monsters first. Stones from the event carry the 1 km distance.
- Smelt event stones quickly. The distance cut applies to them.
- Leave older stones for later. They keep their original distance.
The Help Center explains that each driftstone lists its own distance, so tap a stone to confirm. Also, Insta-Smelt Solution completes the process instantly if you would rather skip walking.
Other Event Bonuses
The event adds three more perks.
| Item | Detail |
|---|---|
| Field access range | Up 50% |
| Group hunts | One extra materials slot |
| Part breaks | Double material payouts |
These perks help you farm. For example, double part breaks pay off most with a build that includes Partbreaker, although you need a stone to get the skill.

Driftgem V Shard Exchange Requirements
Your keywords ask about a Mysterious Driftgem V. I could not confirm the exchange cost for it. The sources I read do not cover it. However, the Help Center explains how shards work in general:
- Shards: each driftsmelt gives one driftstone shard as a byproduct.
- Cap: you can hold up to 300 shards.
- Exchange path: open the Driftsmelting Tank, then the Driftstone Shards icon.
- Driftgems: each one holds a single skill type and guarantees that skill.
- Exclusive gems: some driftgems come only from this exchange.
In addition, the event notes say the Halloween 2026 Exchange Hubs stay open until November 15, which is a week after the event ends. So you have extra time to spend shards. As of the latest update, check the exchange screen for the exact cost.
Best Armor to Smelt Mysterious Driftstone V
No source I found names a best armor piece, so I will not invent one. The Help Center does list the rules that decide it:
- Open slot: the equipment needs an open driftsmelt slot.
- Overgrade level: the gear needs the required overgrade level, which varies.
- Skill cap: equipment can save up to 20 skills.
My suggestion, and it is advice, not a confirmed fact: choose a piece that already fits the build you use most, then match the skill to it. For example, if you hunt with an ice weapon, Ice Attack makes sense. Because a smelt adds a random skill from the four, check the stone first, then pick the gear.
Tips and Common Mistakes
- Hunting non-featured monsters. They give standard colors, not Mysterious Driftstone V.
- Waiting until the last day. The event window closes November 8 at 11:59 PM.
- Smelting old stones first. Only event stones get the 1 km distance.
- Ignoring shards. Every smelt gives one, and they feed the driftgem exchange.
- Forgetting the hubs. Exchange Hubs stay open until November 15.
- Smelting without reading the skill. Check the stone’s skill text first.
Conclusion
Monster Hunter Now Mysterious Driftstone V gives one of four skills, and featured monsters guarantee it during the Halloween Driftsmelting Bonanza from October 26 to November 8. Event stones need only 1 km of walking, and the exchange hubs stay open until November 15. The Driftgem V exchange cost and the best armor remain unconfirmed. Everything here is accurate as of October 26, 2026, and the developers may change event details.
