See the DPS your character really deals, find upgrades, and plan what's next. Load a save, paste a build code, or start a plan from scratch.
Your save and game log are read in this browser tab only; nothing is uploaded.
The sim can read skills, items and the passive tree straight from your own copy of Broken Oath. Nothing is uploaded: every file is read in this browser tab.
C:\Program Files (x86)\Steam\steamapps\common\Broken Oath Playtest (in Steam: right-click the game › Manage › Browse local files).BrokenOath, select the Data folder and confirm. Your browser may ask whether to "upload" the files: that only means this page may read them.The page remembers your files in this browser while they are newer than the site's data; Use the site's data at the top switches back.
Paste a code copied from the passive skill tree (BO1.), a saved build plan (BOP1.) or a link from the ItemDatabase planner (broked-db.pages.dev/planner#b=…, or an older broked-db.vercel.app/b/… link, with its rolled items). The code is decoded in this browser.
Click a node to take it (the shortest path is added) or to refund it (nodes that lose their connection go too). Hover for its stats and what it does to the selected skill's DPS against the enemy set on the left. Right-click a node (on a touch screen: tap it, then Never take) to mark it never take: it gets a red cross, and Optimize, Plan and the node values skip it and never path through it. Right-click again to allow it. Heat map: brighter green = more DPS per point spent. Diamonds are Oath Masteries: one opens when you take any of its notables, then click it to swear one of its Oaths. Changes here apply to the Damage tab until you reset or switch character.
