Spirit Board Rarity Guide

The current Spirit Board is not a placement puzzle. Each character equips up to three Spirits, and the game handles their form as they grow. To compare two setups, always check the same three things: direct Attack, bonus lines, and the matching-colour bonus.

Quick colour comparison

Each value is the direct HP / Attack / Defense from one Spirit.

Spirit	Colour	Size 1	Size 6	Damage Boost at 6 / 12 / 18 cells
	Green	1,763 / 117 / 58	2,278 / 151 / 75	+0.5% / +1.0% / +1.5%
	Blue	2,398 / 159 / 79	3,099 / 206 / 103	+2.0% / +2.5% / +3.0%
	Purple	3,262 / 217 / 108	4,216 / 281 / 140	+3.5% / +4.0% / +4.5%
	Yellow	4,438 / 295 / 147	5,736 / 382 / 191	+5.0% / +5.5% / +6.0%
	Red	6,038 / 402 / 201	7,803 / 520 / 260	+6.5% / +7.0% / +7.5%

The same set bonus also gives the same amount of Damage Reduction. It uses the total size of Spirits of that colour: one size-6 Spirit or three size-2 Spirits both trigger the first threshold.

The six growth shapes

These are the shapes the game uses. From left to right: size 1, 2, 3, 4, 5, then 6.

Red

What size really changes

Size	Direct Attack	Bonus lines
1 or 2	increases with each size	0
3	increases	1
4	increases	2
5 or 6	increases	3

Size 6 therefore raises direct stats and can advance the matching-colour bonus, but it does not add a fourth line.

Beyond Red: rainbow bonus lines

Red is the highest colour of the Spirit itself. Rainbow is not a sixth Spirit colour: it is the highest quality of a bonus line after it has been mastered.

• A size-6 Red Spirit stays Red: its direct stats and set bonus do not become a new colour.
• Its three bonus lines can be improved independently to Rainbow.
• Size 6 does not open a fourth line. It keeps three lines and enables their quality to be improved.

The real late-game target for a damage dealer is therefore three size-6 Red Spirits, with nine useful bonus lines, ideally all Rainbow. The set bonus remains the Red set bonus; Rainbow only raises the strength of the relevant bonus line.

Full sets: the readable gap

Three size-6 Spirits of one colour give nine bonus lines and reach the 18-cell threshold.

Three size-6 Spirits	Total Attack	Damage Boost
Green	453	+1.5%
Blue	618	+3.0%
Purple	843	+4.5%
Yellow	1,146	+6.0%
Red	1,560	+7.5%

At the same size, a higher colour always has higher direct stats and a better set bonus. A size-6 Blue set is therefore ahead of a size-6 Green set before bonus lines are compared; the same is true at every colour step.

Full Green or small higher-colour Spirits?

There is no universal rule such as “Purple always beats Green.” Compare the full change, not one item.

Setup	Direct Attack	Lines	Set bonus
3 × Green size 6	453	9	+1.5%
3 × Blue size 1	477	0	none
3 × Purple size 1	651	0	none
3 × Yellow size 1	885	0	none
3 × Red size 1	1,206	0	none

Small higher-colour pieces can bring much more direct Attack, but they can also remove nine lines and a set bonus. They are neither automatically better nor automatically worse.

The in-game decision

When replacing a Spirit on a damage dealer:

1. Compare the total Attack of all three Spirits, not just the new item’s colour.
2. Count the bonus lines gained or lost.
3. Check the matching-colour threshold before and after the change.
4. Keep the setup that improves those three points together.

Three size-6 Red Spirits with good lines are the maximum for direct stats, set bonus, and line count. Rainbow lines are the next late-game step. Before that point, the best piece is the one that gives the best total for that character, not automatically the highest-colour piece.
