🎴 Character Card Standards

This page explains the standard format and rules used for character cards.


📐 Card Dimensions

  • Canvas Size: 800x1120px
  • Print Equivalent: 2.5 x 3.5 inches (at 300dpi, classic card format)

🧩 Layout Regions

Each card is composed of the following sections:

  • Top Name Bar Displays character name
  • Series Text Indicates the collection or set the card belongs to
  • Main Art Zone Character illustration
  • Stats Row Shows 3 core stats:
    • Power
    • Charm
    • Wit
  • Flavor Text Box Optional quote or description
  • Rarity Marker Icon, stars, or color code
  • Artist name - The creator of the Character illustration
  • Kemoverse ID - Unique SHA-256 code generated for the card, based on the information of the card (Ommiting art)

🌟 Rarity Tiers

Each card belongs to a rarity tier which affects both appearance and stat limits.

Rarity Total Stats Cap Visual Features Recommended
Common 100 Plain template, minimal shine
Uncommon 140 Slightly enhanced frame
Rare 180 Decorative borders, mild shine
Super Rare 220 Unique frame, vibrant shine
Legendary 250 Custom art frames, animated effects

🎲 Rarity Distribution Guidelines

The following table shows an example of how many cards you might include in a 20-card pack, but the actual number of cards per rarity is flexible.

What matters most is that rarities follow the percentage limits defined below.
These limits ensure balance across the entire card pool — regardless of total size.

Rarity Max % Allowed Example (20 cards) Weight Notes
Common No upper limit 10 cards (50%) 0.7 Can exceed 50% of total if needed
Uncommon 20% 4 cards 0.2 Should not exceed 20% of total
Rare 15% 3 cards 0.08 Should not exceed 15% of total
Super Rare 10% 2 cards 0.015 Should not exceed 10% of total
Legendary 5% 1 card 0.005 Should not exceed 5% of total

You can include more cards overall (e.g. 40, 100, etc.),
🔒 But rarities from Uncommon to Legendary must not exceed their percentage caps.
🪶 Common cards are the only exception — they can scale freely and fill the remaining space.


🧮 Stat Allocation Rules

Cards have three core stats: Power, Charm, and Wit.

  • The sum of these three stats must not exceed the max for the rarity tier.
  • Stats can be distributed however you want, as long as the total stays within the cap.
  • Minimum stat per field: 0
  • Maximum per stat: Not enforced, but try to keep cards balanced visually and mechanically.

  • 🌱 Common Gray
  • 🔸 Uncommon Green
