Roco Kingdom Flurri Evolution Line: Winterfinch, Swiftwing, Stats and Tailwind Trait

It starts life as a round little snowbird that pecks at fresh snow for fun, and it grows into a sharp-eyed, elegant flier that nobles love. In Roco Kingdom, Flurri and its evolutions Winterfinch and Swiftwing make up a fast, hard-hitting Wing-class line built around one idea: strike first and strike hard. Here is how each stage grows and how to use them.

The evolution line

1. Flurri (No. 018): A bird Jini born in winter, it often curls into a ball to stay warm. It likes to peck at freshly fallen snow with its small beak, both to eat and just for fun.
2. Winterfinch (No. 019): Tiny and round, with a soft ring of down feathers around its eyes and thick plumage that traps heat. It often huddles with its kin to survive cold winter nights.
3. Swiftwing (No. 020): Sharp-eyed and perfectly composed, it carries itself with a quiet elegance that makes it a favorite among nobles. Its down feathers trap heat even in the strongest winds, which boosts its endurance.

All three stages are Wing class and share the same trait.

Seasonal variants

Each stage comes in four looks, one for each season:

1. Original Variant
2. Spring Variant
3. Summer Variant
4. Autumn Variant

Trait: Tailwind

Tailwind raises Skill Power by 50% when the Jini attacks first.

That makes Speed the key stat for this line. The faster it is, the more often it moves first and gets the bonus.

Stats at every stage

Here is how Species Aptitude grows from stage to stage:

1. Flurri, 342 total: HP 54, Physical Attack 77, Magic Attack 33, Physical Defense 65, Magic Defense 44, Speed 69
2. Winterfinch, 456 total: HP 72, Physical Attack 103, Magic Attack 44, Physical Defense 86, Magic Defense 59, Speed 92
3. Swiftwing, 570 total: HP 90, Physical Attack 128, Magic Attack 55, Physical Defense 108, Magic Defense 74, Speed 115

At every stage, this line leads with Physical Attack and Speed. Swiftwing’s 115 Speed and 128 Physical Attack let it trigger Tailwind often and hit very hard when it does.

Size and capture details:

1. Flurri: 0.38 to 0.51 m, 2.77 to 4.5 kg. Gives 16 Starlight and a 1,200 Roco Coin base review reward.
2. Winterfinch: 0.62 to 0.71 m, 8.92 to 12.7 kg. Gives 16 Starlight and a 1,200 Roco Coin base review reward.
3. Swiftwing: 1.43 to 2.04 m, 27.08 to 32.7 kg. Gives 40 Starlight and a 3,000 Roco Coin base review reward.

Class effectiveness

When attacking with Wing skills:

1. Deals ×2 damage to: Flora, Bug and Fighting
2. Deals ×0.5 damage to: Earth, Dragon, Electro and Mech

When defending as a Wing-class Jini:

1. Takes ×2 damage from: Ice and Electro
2. Takes ×0.5 damage from: Flora, Bug and Fighting

All other matchups deal normal ×1 damage. Flora, Bug and Fighting Jinies are perfect targets, since this line both hits them hard and resists their attacks. Electro is the matchup to avoid: it resists Wing attacks and deals double damage back.
