🎁 Drop Rate
Illustration: Drop rate distribution when opening a treasure chest — common items (gray) appear densely, while rare items (Legendary - yellow) have an extremely slim drop rate.
Drop Rate is a term indicating the probability (calculated in percentages) for a specific item to appear when a player defeats an enemy, opens a gold chest, or performs a reward spin (Gacha).
The Drop Rate system is a tool to regulate economic inflation in the game, while simultaneously baiting players into playing a piece of content over and over (Grinding).
1. Basic Rarity Tier Classification
Often encoded by the industry’s global color standard (Born and shaped by World of Warcraft and Diablo):
- White (Common): Drop Rate 80%. Trash you can pick up anywhere.
- Green (Uncommon): Drop Rate 15%. Has decent temporary stat lines.
- Blue (Rare): Drop Rate 4%. Good for the mid-game phase.
- Purple (Epic): Drop Rate 0.9%. High-end staple weapons.
- Gold / Orange (Legendary / SSR): Drop Rate 0.1% or lower. Extremely Overpowered, altering even visual magic effects, coveted by everyone.
2. Dynamic Drop Rate vs Fixed Drop Rate
- Fixed Drop Rate: The probability of dropping a rare sword is always 1%. Killing 1,000 monsters might not drop it if you’re unlucky.
- Dynamic / Pseudo-RNG: To reduce the unfairness of pure Mathematics. Every time an attack doesn’t drop a card, the algorithm secretly “adds” a small percentage of luck to the next attack. If the item drops, the rate resets to 0%. This avoids players crying in frustration from a continuous streak of bad luck and rage-quitting the game.
