Experimental Hogyoku Shards are the specific resource that rerolls your weapon form in VV: Ultimatum, meaning your Shikai, Schrift, or Resurrección appearance. They are different from the ability-type rerolls that change your power category, and you cannot pull them straight out of mission chests. You make them through a Hogyoku.
Quick answer: Farm regular Hogyoku Shards from high-difficulty mission chests and Rift chests, craft a Hogyoku at a crafting station, then select wish #2 to receive seven Experimental Hogyoku Shards. Spend those shards to reroll your race weapon form.
What Experimental Hogyoku Shards do
These shards reroll the weapon form tied to your race power. That covers the Shikai, Schrift, or Resurrección weapon appearance. They do not change your ability type, and they do not touch your stats or skill tree. If you want a different power category instead, that is a separate roll handled by a different Hogyoku wish.
Note: a weapon form reroll is cosmetic to your race weapon, while ability type rerolls (Shikai/Schrift/Res) are a different option entirely. Keep the two apart so you do not waste resources expecting the wrong outcome.
How to get Experimental Hogyoku Shards
You earn Experimental Hogyoku Shards by crafting a regular Hogyoku first and then claiming the correct wish. There is no mission that drops the experimental version directly.
All seven Hogyoku wishes
When you use a Hogyoku, it opens seven wish options. Wish #2 is the only one that gives Experimental Hogyoku Shards, so pick carefully.
| Wish | Effect |
|---|---|
| 1 | Relocate build points (stat reset) |
| 2 | Seven Experimental Hogyoku Shards (weapon form reroll) |
| 3 | Seven ability rolls (Shikai/Schrift/Res type reroll) |
| 4 | About 5,000 tokens |
| 5 | Reroll all four Hollow traits |
| 6 | Ultimate mastery on one technique |
| 7 | Refund toolbar skills (partial skill reset) |
Redeem a code for free shards
You can also pick up Experimental Hogyoku Shards from an active code without crafting a Hogyoku. The code SDFIX rewards 5x Experimental Hogyoku Shards and 3x Reiatsu Color Reroll. Codes are case-sensitive, so type it exactly in uppercase or the redemption fails with no clear error.
SDFIX in the box and hit Redeem. The shards and rerolls drop into your inventory. Codes can expire without warning, so claim it sooner rather than later.How to know the reroll worked
After you spend Experimental Hogyoku Shards, your weapon form updates to a new appearance for your Shikai, Schrift, or Resurrección. Rerolls are random, so you may need several attempts before you land the look you want. If your ability type stayed the same and only the weapon changed, the reroll behaved correctly. To swap the ability category itself, use Hogyoku wish #3 instead, which is a separate process.
Game mechanics in VV: Ultimatum can shift with updates, so wish numbering and drop rates may change after a patch. The core flow stays the same: build a Hogyoku from farmed shards, take wish #2, then reroll your weapon form.
