What is Radiant Rune in Sailor Piece?
Radiant Rune is a secret rune that provides a major boost to your luck stat. When equipped, the rune increases your luck by 26%, which directly affects the drop rate of rare items. This bonus can help you get better rewards from:
- Boss fights
- NPC enemy drops
- Rare crafting materials
- Other endgame items
Because of this effect, Radiant Rune is often used by players who want to farm rare items faster.
Radiant Rune Stats
Here are the main stats for Radiant Rune:
- Luck Boost: +26% Luck
- Type: Secret Rune
- Main Benefit: Higher drop rates for rare items
Although it does not increase damage, the luck boost makes it extremely useful for long farming sessions.
Where to Get Radiant Rune
Radiant Rune can only be obtained from Infinite Tower mode. You cannot get this rune from:
- Boss drops
- Quests
- Regular enemies
- Shops or NPC vendors
The only place where Radiant Rune appears is inside the Infinite Tower on Tower Island.
The rune drops randomly while clearing tower floors. Because the drop rate is very low, players usually need to complete many tower runs before finally getting one.
How to Enter Infinite Tower
Before you can farm Radiant Rune, you need to access Infinite Tower mode. Here is how to enter it:
- Go to Tower Island using the teleport system.
- Find the Infinite Tower NPC near the tower entrance.
- Use 1 Tower Key to open the Infinite Tower portal.
- Enter the tower and start clearing floors.
Each run requires one Tower Key, so you should collect multiple keys before starting your farming session.
How to Get Tower Keys
Tower Keys are required to enter Infinite Tower. Without them, you cannot access the mode. The easiest way to get Tower Keys is by defeating enemies on Lawless Island. Mobs in this area have a chance to drop keys randomly. To farm keys faster:
- Defeat groups of enemies continuously
- Stay in areas where mobs respawn quickly
- Collect several keys before running the tower
Having multiple keys lets you run Infinite Tower several times without stopping.
Radiant Rune is one of the most useful runes in Sailor Piece for players who focus on farming rare items. With its 26% luck boost, it improves drop rates across the entire game, making long grinding sessions much more rewarding.
To obtain it, you will need to repeatedly clear Infinite Tower on Tower Island using Tower Keys. The drop rate is low, so patience is important. However, while farming for Radiant Rune, you will also collect other valuable rewards from the tower, making the grind worth the effort in the long run.
