Disaster Plants is the latest Cursed Technique in Kaizen, modeled after Hanami from Jujutsu Kaisen. It leans entirely on wide-area attacks that root, trap, and grind down enemies across large patches of ground. Getting it is less about luck and more about a focused grind through one raid, plus a hefty pile of crafting materials.
Quick answer: Talk to Dr. Shiro Kato in the school courtyard and buy Disaster Plants from the Permanent Cursed Techniques section of the Curse Shop for 4,000,000 Yen, 50 Grade 2 Cores, 35 Grade 1 Cores, 25 Cursed Petals, and 10 Cursed Roots. Cursed Petals and Cursed Roots drop only from the Forest of Ruin Raid.
Materials needed to unlock Disaster Plants
The purchase only becomes available once you carry the full material set along with the Yen cost. Two of the five items are tied to a single raid, so plan your farming around that. Grade Cores come from regular enemies during normal play, while Yen accumulates naturally as you fight.
| Material | Amount | How to get it |
|---|---|---|
| Grade 2 Core | 50 | General enemy drops |
| Grade 1 Core | 35 | General enemy drops |
| Cursed Petal | 25 | Forest of Ruin Raid |
| Cursed Root | 10 | Forest of Ruin Raid |
| Yen | 4,000,000 | General gameplay |
Forest of Ruin Raid requirements and drops
The Forest of Ruin Raid is the only place Cursed Petals and Cursed Roots come from, which makes it the real bottleneck. It opens at Level 300 on Easy and scales all the way up to Nightmare, which demands Level 930. Difficulty directly changes your material odds, and Nightmare carries far better rates than the lower tiers.
| Difficulty | Level requirement |
|---|---|
| Easy | 300+ |
| Nightmare | 930+ |
Every clear guarantees Yen. The rarer materials and cosmetics depend on difficulty and luck. The rates below reflect Nightmare runs, which is where you want to farm if your level allows it.
| Drop | Drop rate (Nightmare) |
|---|---|
| Yen | 100% |
| Cursed Root | 70% |
| Cursed Petal | 35% |
| Verdant Necklace | 95% |
| Hanami’s Vambrace | 45% |
| Domain Shard | 1.63% |
Note: Cursed Petal sits at a lower rate than Cursed Root even though you need more than twice as many of them. Expect Petals to be the slowest part of the grind, so keep running Nightmare even after your Roots are done.
All Disaster Plants moves and mastery levels
The kit is built around branch, root, and flower attacks that hit wide areas. Range and damage climb as you raise mastery, and new moves unlock at set mastery thresholds.
| Move | Mastery | Effect |
|---|---|---|
| Branch Trap | 0 | Hold to charge, then release for AoE damage in a circle around you, trapping nearby enemies |
| Death Flower Combo | 20 | Short charge, then a forward attack that grows branches and bushes for AoE damage in a straight line |
| Branch Caller | 65 | Charges for a few seconds, then raises two huge branches from the ground for straight-line AoE damage |
| Shining Sea of Glowing Branches (Domain Expansion) | 75 | Pulls you and nearby enemies into a flower garden that cuts your cooldowns, boosts skill damage, and adds AoE radius |
| Flower Beam | 100 | Summons a giant flower that charges briefly, then fires a large pink beam in your aimed direction for heavy AoE damage |
How to unlock the Domain Expansion
Hitting Mastery Level 75 alone does not give you Shining Sea of Glowing Branches. To turn it on, speak with Hakaze inside Jujutsu Tech and hand over 10 Domain Shards. The Domain Expansion only becomes usable in combat after that exchange is complete.
Domain Shards drop at a 35% rate on Nightmare difficulty, so you can collect them during the same Forest of Ruin runs you do for Cursed Root. Keep farming Nightmare and you will gather Shards alongside your unlock materials.
Best clan for Disaster Plants: Hanami Clan
The Hanami Clan is the strongest pairing for this technique. Its Genetic Hardening passive lines up directly with the kit, and since every Disaster Plants move pulls from Cursed Energy output, the clan’s stat spread matches almost perfectly.
| Stat bonus | Amount |
|---|---|
| Melee | +10 |
| Cursed Energy | +10 |
| Stamina | +9 |
| Defense | +13 |
| Weapon | +6 |
| Cursed Energy DMG % | +3.75% |
| HP % | +3.75% |
| Max Cursed Energy % | +8% |
You will know the unlock worked when Disaster Plants shows up as a selectable Cursed Technique in your loadout after buying it from Dr. Shiro Kato. If the purchase option stays greyed out, the cause is almost always a missing material or short Yen, so recheck your inventory against the full list before heading back into the Forest of Ruin.
