As Dungeon Master you can run as many campaigns as your fragile sanity allows, and your players can waltz right in. Making a character takes a few clicks — slap on a token image, a name, and the handful of numbers you need for beating things to death.
Clean interface, fully web based — all you need is a browser and questionable judgment. Right-click any token for a menu of ways to mess with it.
A no-nonsense combat system using Dungeons & Dragons 5th edition rules so you can focus on the violence. Throw enemies into the fight, roll for initiative, see who swings first. Add goblins, boot players from the combat, deal damage or grudgingly heal — all from a click or a command. Right-click a token for the whole murder menu.
A sidebar spews messages and a command bar at the bottom lets you boss objects, the battle, and the game around. Shout at everyone, or whisper dirty secrets to one player. There's a shared journal too, for the notes nobody will read.
Beyond tokens, Scumbags lets you splatter visual effects on the map on the fly — fire, poison gas, smoke, magic portals, the works.
While building a map, the Dungeon Master can stash loot inside tokens for the players to grub up. The Inventory window keeps tabs on everything they've pocketed.
Build your own token library and carpet your maps with monsters and junk by dragging them straight onto the battlefield. Lazy and glorious.
Maps can have walls, doors and windows — handy for penning your players in and deciding exactly how little they get to see.

An easy fog of war system with three flavors. Day mode: players see until a wall or shut door says otherwise. Night mode: sight is capped by how far the character sees in the dark — light up areas with lights. And manually reveal mode, where the DM scrubs away the fog paint-style, like a petty god.

Drop zones on a map to mark an area — a spell effect, say. The DM can bolt a script onto a zone to do the boring work, like shoving a character to another floor when they take the stairs.
Hunting down the perfect map eats hours nobody has. So scribble your own — grab the empty grid map and go to town like a maniac with felt pens. A few minutes later you've got a battlefield. Add your own textures and effects if you've got taste.
The Adventure Market is stuffed with ready-to-run adventures — the legendary Lost Mine of Phandelver, the Curse of Strahd, and a pile of shorter ones scraped off the internet. The maps come pre-loaded with walls, windows and doors for the fog of war.
Learning a VTT can melt your brain, so Scumbags has Cauldey. He's a measly CR 0 tiny beast, but the little gremlin knows this place inside out. He'll point at the right buttons and drag you through making your first adventure — plus all the other tricks a Dungeon Master needs.
