Runes

How runes work

• Runes have their own inventory category; open your inventory, scroll right to the Runes section, and equip one rune at a time.
• Most runes drop from Rune Dungeons, which have Easy, Medium, Hard, and Extreme difficulty settings and 15 waves each run.
• Published rune chance notes usually use W1, W5, W10, and W15 as the shorthand checkpoints for each run.
• Secret runes are separate from the normal dungeon pool and come from Infinite Tower instead, not Rune Dungeon.

Current rune tier list

Rune	Rarity	Tier	Base stat	Max stat	Why players use it
Primordial Rune	Secret	S+	+75% Damage	+120% Damage	Best overall damage rune and the top rune for max DPS builds; this is an Infinite Tower chase rune, not a Rune Dungeon drop.
Radiant Rune	Secret	S+	+17.5% Luck	+28% Luck	Top luck rune and one of the two current endgame chase runes from Infinite Tower, not Rune Dungeon.
Havoc Rune	Mythical	S	+55% Damage	+88% Damage	Best non-secret damage rune in the current wiki rankings.
Wrath Rune	Mythical	A	+40% Damage	+64% Damage	Very strong raw damage rune and one of the best Rune Dungeon drops.
Fortune Rune	Mythical	A	+10% Luck	+16% Luck	Best non-secret luck option for drop and crate farming builds.
Destruction Rune	Legendary	B	+25% Damage	+40% Damage	Strong direct damage rune and a good bridge before the best mythicals.
Inferno Rune	Mythical	C	Burn 70% Damage over 4 seconds	Burn 112% Damage over 4 seconds	Burn damage is decent, but it does not keep up with the best current choices.
Blood Rune	Mythical	C	Bleed 65% Damage over 5 seconds	Bleed 97% Damage over 5 seconds	Bleed is useful, but it trails the highest raw damage runes.
Frost Rune	Legendary	C	Freeze 2 seconds and +30% Damage	Freeze 3.2 seconds and +48% Damage	Freeze utility is nice, but it is not a top-end damage rune.
Guardian Rune	Epic	C	+39% Max Health	+62.4% Max Health	Solid health padding, but lower value than damage and luck runes.
Suppression Rune	Rare	D	10% Damage Reduction	16% Damage Reduction	Lowest-impact defensive rune and usually replaced quickly.

How to level up runes

• Max Rune Level is 60.
• Any rune you obtain adds +1 Rune EXP, no matter which rune type or rarity it is.
• You need 700 total rune drops to reach max Rune Level.
• Each Rune Level adds +1% potency, so Rune Level 60 gives a 1.6x multiplier to a rune's base effect.
• Rune Level is shared across your rune collection, so your total rune drops decide how effective every equipped rune becomes.
• This works more like artifact milestones than separate per-rune leveling: you are raising the global Rune Level, not feeding duplicates into one specific rune.

Secret rune notes

• Radiant Rune is the main Infinite Tower chase rune for luck-focused farming builds.
• Primordial Rune is the main Infinite Tower chase rune for pure damage and top-end DPS builds.
• Both secret runes are tied to Infinite Tower rather than the normal Rune Dungeon pool.
• Higher floors have much better published odds than low-floor farming, and the 2x Drop gamepass boosts both the base and max listed rates shown on the page.
• Secret-rune pity increases by +1 per cleared Infinite Tower floor, with Radiant guaranteed at 6,000 total floors and Primordial guaranteed at 7,500 total floors.
• Secret rune pity is not visible in game, so track floors manually if you are chasing a guarantee.
• Radiant Rune and Primordial Rune do not share pity, so progress on one secret rune does not interfere with the other.

Best rune farming route

• Farm world bosses for Dungeon Keys first, then spend the keys on Hard or Extreme Rune Dungeon runs because both higher difficulty and later waves raise the rune odds sharply.
• If you are pushing a luck build or chasing the rarest drops, Infinite Tower is the route for Radiant Rune and Primordial Rune; higher floors and the 2x Drop gamepass both matter a lot more than low-floor resets.
• Damage-focused players usually aim for Havoc, Wrath, or Primordial first, while farming builds usually prefer Fortune or Radiant.
