Runes are upgrade items in The Forge that attach Traits to your armor, weapons, and pickaxes. Each rune carries one primary Trait and can roll extra secondary Traits, so the same rune can play very differently depending on the rolls you get. Enemies drop them across every world, and you slot them at the Runemaker once your gear has open rune slots.
Every rune in The Forge and how to get it
Runes are split by what they can be applied to. Armor runes only fit armor, weapon runes only fit weapons, and pickaxe runes only fit pickaxes. The quality of each roll is random, and higher-tier runes can grant stronger primary Traits plus more secondary Traits.
| Rune | Slot type | Primary Trait | Where it drops |
|---|---|---|---|
| Ward Patch | Armor | Shield | Monk Panda (Crimson Sakura Isles) |
| Briar Notch | Armor | Thorn | Deathaxe Skeleton, Elite Deathaxe Skeleton, Samurai Ape |
| Rage Mark I | Armor | Berserker I | Elite Rogue Skeleton, Common Orc, Elite Orc, Yeti, Savage Ape, Brute Oni |
| Rage Mark II | Armor | Berserker II | Warlord Oni, Asura's Incarnate (boss) |
| Flame Spark I | Weapon | Burn I | Deathaxe Skeleton, Elite Deathaxe Skeleton, Reaper, Blazing Slime |
| Flame Spark II | Weapon | Burn II | Hellflame Oni (Crimson Sakura Isles) |
| Blast Chip I | Weapon | Explosion I | Bomber Skeleton |
| Venom Crumb I | Weapon | Poison I | Blight Pyromancer |
| Drain Edge I | Weapon | Life Steal I | Reaper |
| Frost Speck I | Weapon | Ice I | Crystal Spider, Diamond Spider, Prismarine Spider |
| Frost Speck II | Weapon | Ice II | Ice Golem (boss) |
| Chill Dust II | Weapon | Snow II | Ice Golem (boss) |
| Developer Sigil | Weapon | Special | Special events or quests |
| Miner Shard I | Pickaxe | Mining Traits | Delver Zombie, Bomber Skeleton |
| Miner Shard II | Pickaxe | Mining Traits | Ice Golem (boss) |
Tougher enemies and higher difficulties tend to drop better runes. Some enemies, including basic Zombies, Slimes, the Crystal Golem, Cthulhu, and the Mountain Ape, do not drop runes at all.
How to unlock rune slots in The Forge
Gear does not come with open rune slots. You unlock them through the Enhancement system, handled by the Enhancer NPC found in every world. Enhancing costs essence and gold, raises your stats, and opens a new rune slot every third enhancement level.
Step 1: Visit the Enhancer in any world and select the weapon or armor piece you want to upgrade. Confirm you have enough essence and gold for the attempt.
Step 2: Enhance the item. Early levels have high success rates, but higher levels fail more often, and a failed attempt drops the item by one enhancement level.
Step 3: Keep enhancing until you reach a slot threshold. A fresh rune slot appears at every third enhancement level, so plan your runs around those milestones.
Pickaxes work differently. You cannot enhance extra slots onto them. The only way to get more pickaxe rune slots is to buy a better pickaxe, such as the Arcane Pickaxe.
Applying runes at the Runemaker
Once you have an open slot, take your rune to the Runemaker station, which appears in every world. Slot the rune into the gear of the matching type, and the Traits apply immediately. Armor runes only go on helmets, chestplates, and leggings. Weapon runes go on any weapon type. Pickaxe runes go on pickaxes.
You know it worked when the rune's Traits show up on the item's stat panel and any visual effect kicks in. For example, a weapon carrying Burn gains a fiery particle effect, Ice adds an icy effect, Poison adds a toxic effect, and Snow adds a snowflake effect.
The Forge rune Traits and what they do
Every rune provides a primary Trait, and most can roll secondary Traits on top. The exact value lands somewhere inside a range, and higher-quality runes roll closer to the top of that range. Many Traits stack with copies of themselves, though several have caps.
Core and defensive Traits
| Trait | Effect | Notes |
|---|---|---|
| Vitality | Increases max health by 5–10% | No cap; stacks |
| Endurance | Increases max stamina by 4–10% | Caps at 200% |
| Shield | Reduces physical damage by 6–14%, 5–15% chance per hit | Caps at 80%; no effect on ranged attacks |
| Thorn | Reflects 2–10% of physical damage taken | Reflect capped at 5% of max HP per proc |
| Berserker I | +12–26% physical damage and move speed for 4–7s below 35% HP | 50–60s cooldown |
| Berserker II | +25–40% physical damage and move speed for 6–11s below 35% HP | 30–50s cooldown |
Mobility Traits (armor)
| Trait | Effect | Cap |
|---|---|---|
| Phase | Increases dash invincibility duration by 4–11% | 90% |
| Stride | Increases dash distance by 8–15% | 75% |
| Surge | Reduces dash cooldown by 3–11% | 75% |
| Swiftness | Increases movement speed by 4–10% | No cap |
Attack Traits (weapon)
| Trait | Effect | Cap |

| Lethality | Increases physical damage by 5–15% | 150% |
| Critical Chance | Increases crit chance by 6–15% | 100% |
| Critical Damage | Increases crit damage by 5–15% | 100% |

Damage-over-time and control Traits
| Trait | Effect |
|---|---|
| Burn I | 5–10% weapon damage as fire per second, 15–25% chance on hit |
| Burn II | 10–22% weapon damage as fire per second, 20–50% chance on hit |
| Poison I | 4–7% weapon damage as poison per second for 1–4s, 25–35% chance on hit |
| Explosion I | 20–40% weapon damage as AoE, 8–20% chance on hit |
| Life Steal I | Heals 4–11% of weapon damage, capped at 8% of max HP |
| Ice I | Freezes for 1–2s, 10–20% chance on hit, 15–20s cooldown |
| Ice II | Freezes for 2–3s, 30–40% chance on hit, 15–20s cooldown |
| Snow II | 12–32% attack and move speed slow for 3–7s, 25–60% chance on hit |
Mining Traits (pickaxe)
| Trait | Effect |
|---|---|
| Luck | Increases overall luck by 5–16%, boosting ore and mob drop chances |
| Yield | 5–15% chance to drop one extra ore from a node |
| Swift Mining | Increases mining speed by 4–12% |
| Mine Power | Increases mining damage by 8–15% |
A couple of timing quirks are worth knowing. Burn ticks once when applied and again each following second, so its real duration runs about one second shorter than the listed number, which is why it can read as low as zero seconds. Poison works the same way but runs about two seconds shorter than listed, bottoming out at one second.
With the right runes slotted, you can steer a build toward raw damage, survivability, mobility, or faster mining, all from the same enhancement and Runemaker loop. Farm the enemy that drops the Trait you need, push your gear's enhancement level to open more slots, and roll for higher-quality runes to squeeze out the best numbers.
