VV: Ultimatum offers several ways to obtain Ability Rerolls and Hogyuku Fragments, but not all methods are equally efficient. Since rerolling abilities is essential for optimizing your build, understanding where Hogyoku Fragments come from and how to farm them efficiently can save dozens of hours of grinding.
The current endgame farming loop revolves around collecting Hogyoku Fragments, crafting a complete Hogyoku, and exchanging it for Ability Rerolls.
Quick overview of Ability Reroll farming
| Method | Difficulty | Solo Friendly | Rewards | Best For |
|---|---|---|---|---|
| Human World PvP | Medium | No | War Medals, Hogyoku Fragments | Guaranteed progress |
| World Events (Bosses) | Hard | Sometimes | Chests, Rift Chests, Fragments | Consistent farming |
| Calamitas (Dragon) | Very Hard | Yes (with experience) | 13 Chests, Rift Chests, Fragments | Fastest farming |
How Ability Rerolls and Hogyoku work
Ability Rerolls are obtained indirectly through the Hogyoku system. Players must first collect seven Hogyoku Fragments. Once all seven fragments have been acquired, they can be combined into a complete Hogyoku.
Using a Hogyoku grants a wish that rewards seven Ability Rerolls. Because of this conversion rate, every fragment you obtain contributes directly toward future rerolls.
| Item | Requirement | Reward |
|---|---|---|
| Hogyoku Fragment | Farmed from bosses, events, or PvP | 1/7 progress |
| Complete Hogyoku | 7 Fragments | 7 Ability Rerolls |
How to farm through Human World Black Market – PvP
This method functions as the game’s guaranteed progression system.
By defeating other players in Human World, you earn War Medals. These medals can be exchanged through the Black Market for Hogyoku Fragments.
The major advantage is consistency. Even if boss drops are not cooperating, you can steadily work toward a fragment.

The downside is the required grind.
PvP Fragment Costs
| Resource | Amount Required |
|---|---|
| War Medals per Fragment | 30 |
| Fragments for Hogyoku | 7 |
| Total War Medals Needed | 210 |
Step 1
Travel to Human World and participate in PvP activities.

Step 2
Defeat opposing players to earn War Medals.

Step 3
Visit the Black Market vendor.

Step 4
Exchange medals for Hogyoku Fragments.

Repeat until you obtain seven fragments.
While effective, this is generally considered the slowest farming method compared to boss farming.
How to farm World Event bosses
World Events provide one of the best balances between difficulty and reward.

These bosses spawn every hour at approximately the 20-minute mark. Upon defeating the boss, players receive multiple loot chests that can contain valuable items, including Hogyoku Fragments and Rift Chests.
Advantages
| Benefit | Details |
|---|---|
| No crafting required | Simply join the event |
| Valuable chest rewards | Multiple loot opportunities |
| Rift Chest drops | Additional high-value loot |
| Server hopping | Fight multiple bosses quickly |
Step 1
Monitor server announcements for upcoming World Events.
Step 2
Arrive before the boss spawns.

Step 3
Attempt to fight the boss solo if possible to maximize loot.

Step 4
Open all earned chests and check for Hogyoku Fragments.

After completion, server hop to find another active event.
Server hopping is one of the most effective techniques because it allows you to bypass waiting for the next spawn timer.
How to farm Calamitas (Dragon)
For experienced players, Calamitas is widely regarded as the strongest farming method available.
The encounter is difficult, but the rewards are exceptional. The dragon drops thirteen chests per clear, including multiple Rift Chests, making it one of the highest-value activities in the game.

Based on player experience, the encounter also benefits from a relatively short cooldown, allowing repeated runs throughout a farming session.
Calamitas rewards
| Reward Type | Amount |
|---|---|
| Total Chests | 13 |
| Rift Chests | 3 |
| Cooldown | 5 Minutes |
Step 1
Acquire the required Ritual Oil to access the encounter.

Step 2
Find a low-population or private server whenever possible.

Step 3
Engage the dragon and learn its attack patterns.

Step 4
Loot all thirteen reward chests after victory.

Wait for cooldown or switch servers and repeat.
Understanding Calamitas attack patterns
Success against Calamitas depends heavily on recognizing its attacks.
The fireball attack is one of the easiest abilities to avoid. Keep moving and maintain awareness of projectile trajectories.

The barrage attack unleashes repeated projectiles and can quickly overwhelm players who panic. Proper timing and defensive abilities significantly reduce incoming damage.
The fire breath phase is often the most dangerous attack. Positioning becomes critical, and players should avoid standing directly in the dragon’s path. Dodging sideways instead of retreating backward generally provides better survival chances.

Learning these patterns transforms the fight from an overwhelming challenge into a reliable farming route.
Farming tips to maximize Hogyoku Fragment gains
The most efficient farmers rarely stick to a single method. Instead, they rotate between available content.

When World Events are active, prioritize them because they require no setup and provide strong rewards. During downtime, move to Calamitas farming if your character is strong enough. Human World PvP should function as a backup method that guarantees progress whenever boss drops are unlucky.
Server hopping remains one of the most valuable techniques in VV: Ultimatum. Rather than waiting for cooldowns or hourly timers, moving between servers dramatically increases the number of bosses you can defeat per hour.
Players who can consistently clear Calamitas while also participating in World Events will generally accumulate Hogyoku Fragments far faster than those relying solely on PvP.
If your goal is to obtain Ability Rerolls as quickly as possible, focus primarily on Calamitas farming while participating in every available World Event. The combination of massive chest rewards, Rift Chest opportunities, and short cooldowns makes it the strongest fragment farming strategy currently available. Human World PvP remains useful as a fallback option, ensuring that every session contributes progress toward your next Hogyoku even when boss drops are not in your favor.
