Runes

Runes are mob drops that either grant passive effects while in inventory or act as rare crafting materials.

Quick Summary

Runes only drop from mobs killed by a player.
Keep runes in your inventory to activate them.
Runes cannot be stored in bundles.
Looting and Rune Multiplier events both increase drop chance.
Rune drops now use scaling RNG: going dry raises your current chance until that rune drops.

Unlock Phases

Season start: Corrupted Mob Soul Rune and Severed Mob Heart Rune can already drop.
Week 1 (SeasonStart + 7 days): full passive rune pool + special runes unlock.

Activation Rules

Inventory runes apply effects while carried (main inventory/hotbar/offhand).
Effect refresh task runs every 199 ticks (about 10 seconds).
If multiple runes give the same potion effect, the strongest tier is used.
Potion Extender runes do not grant a potion effect by themselves. They extend a matching active potion effect by 3 seconds every refresh cycle.
Potion Extender runes only extend normal potion effects that are already active at the same effect level; they do not refresh effects created by other runes.
Runes found inside bundles are automatically removed and returned to normal inventory/drop flow.

Bedrock Visual Note

On Bedrock, some rune effects may not always show clear visual indicators (for example, Luck, Saturation, etc.).
This is a client limitation.
Effects still apply correctly server-side.
Dolphins Grace Rune is temporarily vaulted and currently cannot drop or appear in /runes.
Dolphins Grace Potion Extender Rune can still drop; it only extends Dolphins Grace from another source.

Drop Formula and Scaling RNG

Per eligible mob kill, the flat rune chance starts as:

flatChance = min(1.0, baseChance * (1 + 0.10 * lootingLevel) * runeMultiplier)

baseChance is the rune's built-in drop rate.
lootingLevel is your weapon Looting enchant level.
runeMultiplier is the active server rune event multiplier (1.0 default, 2.0 or 1.5 during events).

Scaling RNG then uses that flat chance to set your current roll chance for each rune:

Your current chance starts lower than the flat rate.
Each eligible kill without that rune increases your current chance.
When that rune drops, its dry streak resets.
The long-term average stays close to the listed flat rate, but long dry streaks are less punishing.
/runes shows both your current chance and the flat rate for each rune, using the Looting level on the item in your main hand.

Rune Multiplier Schedule
