Chrono Synthesis Box

Box of Synthesis

Box of Synthesis is a random reward box that grants 1 item from a predefined reward pool when opened.

How it works

When a player opens the box, the script performs a weighted random roll based on a total chance pool of 100.00% (10,000 points).

Some items have fixed special rates:

• 100601 — 15.00%
• 100602 — 8.00%
• 23436 — 8.00%

All remaining items share the leftover chance equally.

Reward Distribution Logic

The script uses a total pool of 10,000 chance points.

Fixed-rate items

• 100601 = 1500 points = 15.00%
• 100602 = 800 points = 8.00%
• 23436 = 800 points = 8.00%

Total fixed chance:

• 3100 points = 31.00%

Remaining chance:

• 6900 points = 69.00%

This remaining chance is divided among the other 27 entries in the pool.

Because the division is not perfectly even:

• the first 15 non-fixed entries receive 256 points = 2.56%
• the remaining 12 non-fixed entries receive 255 points = 2.55%

Important Notes

• Some items appear more than once in the pool.
• If the same item ID appears multiple times, each entry is rolled separately.
• This means duplicated items have a higher total combined chance.

For example:

• 100058 appears twice
• 536 appears twice

So their effective total chance is approximately doubled.

Rare Drop Announcement

The script sends a global announcement when the obtained item's chance is 8.00% or lower.

This includes:

• all shared-pool items
• 100602
• 23436

The following item is not announced because its chance is above the threshold:

• 100601 — 15.00%

Summary

• Total reward pool: 100.00%
• Highest chance item: 100601 at 15.00%
• Mid-tier fixed items: 100602 and 23436 at 8.00%
• All other items: approximately 2.55%–2.56%
• Duplicate entries increase the effective drop chance of those items
