Runes in Iron Soul: Dungeon — Best Runes & Enchant Guide

Four runes exist in Iron Soul: Dungeon: Burn, Frost, Corrode and Methysis. All four appear in the official-branded rune template and in community item lists, and both sources describe the same effects. Some guide sites publish only three and drop Methysis entirely, and older pages call Burn by the name Fire — so the count and the spelling are both worth checking before you plan an Iron Soul: Dungeon build around them.

A rune in Iron Soul: Dungeon pays its full rolled value in a weapon slot, 60 percent in body armor and 40 percent in a helmet. The multiplier is a flat percentage, so you can compare slots without knowing any hidden numbers: three copies of one rune across all three slots total 2.0x, not 3x. That is why the recommended layout puts your best rune on the weapon and treats the helmet as the slot for the effect you care about least.

Enchanting in Iron Soul: Dungeon costs gold on a fixed ladder set by the rune’s level: 2,400 gold at level 1, 3,600 at level 2, 4,800 at level 3, 6,000 at level 4 and 7,200 at level 5. The cost is identical whichever slot you enchant — weapon, body or helmet — so the price never decides the slot for you in Iron Soul: Dungeon.

Three documented sources in Iron Soul: Dungeon: the Cave of Runes dungeon, the grocery shop (roughly 3,000 gold for a level 3 rune), and the season battle pass. The enchant menu itself runs through the NPC Milo. Because removing a rune destroys it, every rune you socket in Iron Soul: Dungeon should be treated as a one-way decision.

No — upgrading a rune in Iron Soul: Dungeon is a reroll, not an upgrade. Raising the level redraws all hidden values at once: proc chance, damage, duration and tick damage are all rerolled, and a higher level only widens the possible range. A lucky low-level rune can beat a fresh high-level one, so compare before you swap — and remember the old rune is not recoverable once broken out of a piece of gear.

It depends on your stage of the game, and the community answer is consistent: early on, Burn or Methysis lead because their damage-over-time ticks are a large share of a small total. In the endgame, Corrode takes over — it weakens the target and increases the damage everything else you do deals, so it scales with your gear instead of adding a fixed amount. Frost is the utility pick: it slows before dealing bonus damage at the end of the effect.

Rune Crack is an item rather than a rune — its job is to remove a rune from an enchanted piece of gear. The removal destroys the rune itself, which is the single most important lifecycle rule in Iron Soul: Dungeon enchanting: socket deliberately, because un-enchanting is a loss, not an undo.
