Cid Kagenou V2 is the Shadow-themed spec added in the Red Dungeon update for Rock Fruit, and it sits among the strongest weapons in the game. It is also one of the hardest to unlock. The upgrade is gated behind rare drops and a low-odds craft, so the path matters more than raw luck.
Quick answer: Own Cid V1 first, then go to Event Island and hand over one Blade Shadow and one Blood of Shadow to complete the upgrade to Cid V2.

What you need before upgrading to Cid V2
You cannot skip straight to V2. Cid V1 is a hard requirement, and the upgrade itself is handled at Event Island, the area marked by the large rainbow and the rainbow-colored buildings and trees. Bring both upgrade items with you before talking to the NPC there.
| Requirement | How to get it |
|---|---|
| Cid V1 | Must already be unlocked; it is the base for the V2 upgrade |
| Blade Shadow | Chest or dungeon rewards, or farm the new island’s mobs at a 0.3% drop rate |
| Blood of Shadow | Crafted item with a 5% success rate per attempt |
Note: Hold onto these materials. It is easy to trade away items that turn out to be far more valuable than they first appear, so avoid parting with anything Shadow-related until Cid V2 is finished.

Blade Shadow comes down to luck. It appears as a random drop from chests and dungeon rewards, or from farming mobs on the new island. The mob drop rate is only 0.3%, which means long farming sessions before one appears. There is no guaranteed method, so expect to grind unless a chest rolls in your favor early.

How to craft Blood of Shadow
Blood of Shadow is the harder half of the upgrade. It is a craft with a 5% success rate, so on average you will fail roughly 19 times before a single craft succeeds. Each attempt consumes the same set of materials, which is what makes this step so demanding.
| Crafting material | Where to find it |
|---|---|
| Orb Atomic | Found in chests |
| Glass Tube | Found in chests |
| Orb Blood | Red Dungeon Shop for 30 dungeon points each, or a rare Iris Boss drop |
Orb Atomic and Glass Tube are the easy pieces since both drop from chests. Orb Blood is the bottleneck. Buying it from the Red Dungeon Shop is the reliable route at 30 dungeon points per orb, while farming the Iris Boss for it is possible but has very low odds.

Planning the grind
Because the craft can fail so often, it helps to stockpile materials before you start rolling. To reach a near-guaranteed success rate through repeated attempts, plan for about 10 Orb Atomic, 10 Glass Tubes, and 10 Orb Blood.
Buying those 10 Orb Blood costs 300 dungeon points, which works out to roughly 25 or more hours of straight Red Dungeon runs to accumulate. If an early craft succeeds, you save a huge amount of time. If it does not, this is where most of the effort goes.
Completing the upgrade

Cid V2 moveset and payoff
The reward for finishing the grind is a spec that dominates both bosses and PvP. Its basic attacks are fast and smooth, and its kit combines a spammable strike, a full time stop, and a one-shot finisher. In the Red Dungeon it can one-shot the Aegis boss and even the Gojo boss.
| Key | Move | Notes |
|---|---|---|
| Z | Quick Strike | Decent range and damage on a 2-second cooldown, easy to spam |
| X | Time Stop | Stops time for 10 seconds, strong in both PvP and boss fights |
| C | Atomic Slash | Standard AoE attack on a 20-second cooldown |
| V | Cutscene Attack | High damage with one of the game’s best-looking cutscenes |
| F | One-shot finisher | Short cooldown, can one-shot bosses and players |
The F move is the single reason the grind is worth it, since its short cooldown and massive damage make it borderline broken against the strongest bosses. The main downsides are the punishing farm for Orb Blood and a C move that feels underwhelming next to the rest of the kit. If you can survive the material grind, Cid V2 is one of the most powerful weapons Rock Fruit currently offers.
