DM encounter manager
Write up every creature in an encounter as free-form notes, keep them in your running order, and run the fight from one page. Free, in the browser, saved on your own device.
What the encounter manager does
Each encounter is a stack of creature cards you write yourself, in plain text with a light markdown hand: headings, bold, lists, tables, stat lines and dice. Click a card to edit, click away and it renders. Drag the grip to keep the cards in the order you run them.
Give a creature an HP: line and it gets a hit point bar derived from it. Click the bar to damage or heal in play, and duplicate a card when a second goblin joins the fight. Roll initiative from the encounter bar: every creature rolls with a modifier read from its DEX, and the cards sort into turn order.
Keep recurring creatures under Your creatures on the encounters screen: build one in the editor or save one from a card's menu, and add it to any encounter from the Add creature menu.
Encounters and saved creatures are kept in your browser automatically. Nothing leaves your device. Export an encounter or a creature as a JSON file to back it up or hand it to another DM, and import it on any device.
