About
The forge never sleeps
Oathforge Idle is a dark Nordic idle and incremental RPG. Run gathering and production professions, equip tools, forge gear across a deep tier ladder, push open-world combat and sealed dungeons, and invest into a branching passive tree of Oaths. Play the full solo game offline on Windows. Online realms use the same loops under a server-authoritative world — when they open, your craft and combat still mean the same things.
Systems
Gather. Craft. Fight. Swear an Oath.
Dark Nordic idle systems built for long campaigns — honest progression, deep crafts, and builds that reward planning.
Mining
Woodcutting
Fishing

Alchemy
Fletching
Tailoring
Idle professions
Mining, woodcutting, fishing, hunting, cooking, smithing, alchemy, and more — workers keep the hall productive while you plan the next forge.
The Forge
Craft weapons, armor, and profession tools across a deep tier ladder. Boss uniques and set pieces define endgame identity.
Combat & dungeons
Open-world zones, sealed dungeon runs, party packs, and guild-scale threats — loot and progression that scale with your build.
Tree of Trails
A branching passive board of clusters and Oaths — not a flat skill list, a map of who you become.
Classes & companions
Warrior, Archer, and Shaman cores with rich portrait fantasy and companion support for the road.
Offline first, online true
Solo play is complete and local. Online is the same game with account progress — not a different product bolted on.
Character select
Full roster — 12 classes
Three families. Twelve paths. Male and female heroes with unique quirks — the same cards you see at character select in-game.
Strength
Physical damage · holds the line
Dexterity
Piercing damage · strikes at range
Intelligence
Magic damage · mends and unmakes
Torstein
Hersir
Character select
Torstein
Hersir · Warrior
“Stand at the front and refuse to move.”
A hersir holds land by holding the line, and answers to no jarl who will not stand in it beside him. He is the sworn point of the shield-wall, first to close and last to give ground. Where the hersir plants his standard, the war-band forms.
Strengths
- · Holds enemy attention off softer allies
- · Heavy armour and a deep health pool
- · Trades blows as readily as it absorbs them
Weaknesses
- · Little answer to a foe that will not close
- · Slow to reposition once committed
Gender quirk
Standard-Bearer+4% threat generation
Tree of Trails
Clusters, Oaths, and routes — not checkboxes.
Progression
Walk the map of who you become
Invest into a branching passive board of clusters and Oaths. Builds are routes through the tree — Path of Exile–inspired depth without a flat skill list.
- ·Oaths that define identity at key nodes
- ·Cluster paths for combat, craft, and support
- ·Long-term build planning that rewards patience
The Forge
Tools, materials, and spoils
Turn raw materials into weapons, armor, and profession tools. Climb the tier ladder, chase rarity, and hunt uniques that rewrite how you play.
Profession tools
Gathering & production
Combat loot
World
Zones, seals, and sealed runs
Clear open land, spend seals on dungeons, and face packs that demand real builds — not just bigger numbers on a spreadsheet.
Threats of the North
Creatures and champions that test your gear, Oaths, and party line.
