Aniimo’s grass swordsman has a variant listed as No. 34B: Thunderstorm Thornblade. Its dark black-rose appearance and bright purple electrical aura set it apart from the standard form. Evolution cannot produce this variant; it appears only when bad weather reaches the Sea of Flowers.
Quick answer: Wait for rainy or thunderstorm weather in the Sea of Flowers, travel to -0224, 0688 by the ruined tower, and catch the aura-wrapped Thornblade with an Anipod before it dies.
Spawn conditions for Thunderstorm Thornblade
Weather determines whether this variant can appear. It is absent from the world during clear conditions, even after repeated area reloads. Use the map’s weather tab to track an approaching rain or storm period, and go there when it begins.
- You’ll find it in the Sea of Flowers only when conditions are rainy or stormy.
- The game allows just one Thunderstorm Thornblade to be present at any given time.
- Catching or defeating it prevents it from appearing again.
- It cannot be obtained through evolution, since there is no Thunderstorm Budsquire to evolve from.
Treat this as a one-shot encounter. If you knock it out by mistake, the variant remains unavailable until the weather changes, because the spawn will not return.
Thunderstorm Thornblade location in the Sea of Flowers
Find the spawn at -0224, 0688, on the purple-flowered grassy hill northwest of the Alpha Irisal boss arena. A ruined tower stands nearby, alongside a small, round building with white walls; the Thornblade is close to the building’s entrance. Its level is low, making the capture more challenging than the battle.
How to catch Thunderstorm Thornblade
A successful catch triggers the capture animation and displays a Completed Research banner. It also completes the line’s “Defeat this Aniimo 0/1” task. In the Anilog, find entry No. 34B and confirm that Thunderstorm Thornblade is registered with its encounter level. You will also receive the Pale Thorn, described as follows:
This item stands as evidence of triumph over Thunderstorm Thornblade.
Convert a Thornblade using a Morph Orb
Once you have caught a Thunderstorm Thornblade at least once and it is registered to your Aniilog, you can turn any basic-form Thornblade into the Thunderstorm form with a Morph Orb. This is the reliable route for a second copy without waiting on the weather.
Stock is capped at 10 Morph Orbs per week before it refreshes.
Force extra spawns with the Nurture feature
If it is already rainy or stormy in the Sea of Flowers, you can pull multiple Thunderstorm Thornblades into the world by using the Nurture feature at the local Bloom with a Grass Shard Nurturing Offering. This is an expensive method once your free nurtures are gone, so save it for when you want several copies in a single weather window.
Thunderstorm Thornblade stats, elements, and skills
With Grass and Lightning elements, Thunderstorm Thornblade is a Nova stage DPS, whereas its base form is Grass alone. Its stats match those of the standard form. Water and Earth are its strong matchups; Fire, Dark, and Wind are its weaknesses.
| Stat | Value | Stat | Value |
|---|---|---|---|
 HP | 96 | P.Def | 74 |
 Attack | 121 | M.Def | 73 |
| Magic Attack | 121 | Break | 53 |
| Regen | 92 | Dex No. | 34 |
Each skill used adds a stack to its Sword Dance trait, up to a cap of four. Stacks remain for 15 seconds; a basic attack spends one to deal 180 percent extra damage. In the Homeland, it grants Artisanship Lv. 3, Grass Lv. 3, and Lightning Lv. 2.
| Skill | Element | EP | Power |
|---|---|---|---|
| Thorny Defense |  Grass | 20 | 75 |
| Aqua Defense |  Water | 20 | 75 |
| Thorny Impact | Grass | 20 | 57 |
| Lightning Impact |  Electric | 20 | 57 |
| Thorny Rain | Grass | 10 | 30 |
| Elegant Waltz (Ultimate) | Grass | 0 | 172 |
Build the kit around critical hits: landing either dash, Thorny Impact or Lightning Impact, grants 15 percent Crit Rate for 15 seconds. Thorny Defense reduces incoming damage by 20 percent and counters when you’re hit in stance; casting it as an attack arrives also grants 30 percent Crit Rate. With Aqua Defense, a perfectly timed block applies Lockdown for 12 seconds instead of granting that crit bonus. Use skills to build Sword Dance stacks, spend them on basic attacks, then finish with Elegant Waltz after the buffs take effect.
