Ragmon Merge

The Ragmon Merge feature in Ragnarok: Monster World provides a strategic method to enhance Ragmon NFTs. By merging multiple Ragmons of the same rarity, players invest $ZENY—with costs varying by rarity—to potentially increase a Ragmon’s level. This mechanic adds depth to gameplay and resou_rce management, making Merge a key component of progression within the Ronin ecosystem.

Creating Value Through Systematic Burning

The Ragmon Merge process systematically reduces the supply of lower-level Ragmons, thereby increasing the inherent value of higher-level NFTs. For example, with a 50% success rate and a Merge cost of 10 ZENY, and assuming the average price of a Level 1 Common Ragmon is 100 ZENY, the expected price for a Level 2 Common Ragmon can be calculated as follows:

$$(2∗10 ZENY)+(base 100 ZENY+(material 100 ZENY∗2))=320 ZENY$$

This cost structure and success probability help establish an intrinsic value for upgraded NFTs, as fewer lower-level Ragmons remain in circulation while higher-level ones become more desirable.

Transparent Control of NFT Supply

The Merge system offers a transparent way to regulate the total supply of Ragmon NFTs. By adjusting Merge costs and upgrade probabilities, DAO governance can incrementally modulate the number of NFTs in circulation, helping maintain a balanced and sustainable in-game economy.

Success Rate Calculation

The Merge success rate depends on three key factors: base probability, accumulated value, and the level of the material Ragmons involved. Each level carries a specific base probability—for instance, 10% for Level 2, 5% for Level 3, and 2.5% for Level 4. The following section explains how these probabilities are applied.

• Level 1 → Level 2

  • Each Level 1 Ragmon used as material contributes 10% to the success rate. Therefore, merging two Level 1 Ragmons results in a 20% overall rate.

• Higher-Level Merges (e.g., Level 3 → Level 4)

  • A Level 1 Ragmon provides 2.5%.

  • A Level 2 Ragmon is assumed to have consumed 10 Level 1 Ragmons (since it had a 10% chance to upgrade), resulting in an accumulated value of 11. Multiplying 11 by 2.5% gives 27.5%.

  • Combining one Level 1 (2.5%) and one Level 2 (27.5%) Ragmon yields a total success rate of 30%.

• Failure Outcome - Yggdrasil Berries: If the attempt fails, there is a chance to receive Yggdrasil Berries based on the Ragmon’s rarity and accumulated value. These can be used to increase the success rate of future Merge or Upgrade attempts, functioning as supplemental materials within the enhancement system.

Variables

• $P_b$: Base probability of success for the target level (e.g., 10% for level 2, 5% for level 3, 2.5% for level 4, etc.)
• $n_1$: Number of level 1 material Ragmons used in the merge
• $n_i$: Number of material Ragmons of level ( i ) used in the merge
• $A_i$: Accumulated value of a level ( i ) Ragmon (statistical value based on merging probabilities)

Accumulated Value Calculation

The accumulated value $A_i$ for a level $i$ monster can be expressed as:

$$A_i = 1 + \sum_{j=1}^{i} \left( \frac{1}{P_b^j} \right)$$

Where $P_b^j$ is the base probability for level $j$.

Success Rate Calculation

The success rate $P_s$ for the level merge can be expressed as:

$$P_s = P_b \left( n_1 + \sum_{i=2}^{N} n_i \cdot A_i \right)$$

Where $N$ is the highest level of material monster used in the merge.

Example Calculation

Let's go through an example:

• Target level: 4

• Base probabilities:

  • $P_b^2 = 10\%$
  • $P_b^3 = 5\%$
  • $P_b^4 = 2.5\%$
• Material Ragmons:

  • $n_1 = 1$ (level 1)
  • $n_2 = 1$ (level 2)

Step-by-Step Calculation

1. Calculate accumulated values:

   • $A_2 = 1 + \frac{1}{P_b^2} = 1 + 10 = 11\%$
2. Calculate success rate:

   • $P_s = 2.5\% \left( 1 + 1 \cdot 11 \right) = 2.5\% \times 12 = 30\%$
3. As a result, merging from Level 3 to Level 4 with one Level 1 Ragmon and one Level 2 Ragmon yields a 30% success rate.

Merge costs are periodically adjusted based on market conditions, and any changes will be announced through the social channels.
