This is like a Dungeon Master's Assistant for running a slick and efficient DnD session! A lot of the things you need to open another window/tab for, look up in books, or scribble down on scraps of paper, can be done right on your mobile phone -- and done better and faster. The entire open source Dungeons and Dragons 5th Edition (2024) rules are at your fingertips! Running a combat and tracking initiative is fast and easy with all the key stats right there. You have instant access to basic monster stat blocks, armor classes, hit points. Sound effects, images, quick NPC creation -- all right there in your hand. This is great for the hybrid Dungeon Master who may be running a remote or in-person session and also has players using tools like DnD Beyond, or the dungeon master previously running a pure in-person with paper and no screens at all. Here's what it can do: --[FREE] D&D 5th Edition (2024) System Reference Document (SRD) 5.2, with easy to navigate table of contents. All the rules, spells, monsters, magic items, etc. right here. Note: Does not include copyrighted material found only paid reference books. --[FREE] Dice roller - You have to always have one of these handy, right? Track multiple rolls with convenient sum. --[FREE] Quick reference for PC's and NPC's in your campaign. The key stats you need quick access to on the fly, like HP and Passive Perception. This is also great when trying to keep all the names and classes and races straight with your new players. It's a PC Cheat Sheet, especially useful for new campaigns. Your players will appreciate this too when getting to know each other. --[PAID] Combat is where DM Copilot really shines. Quickly add new monsters, track initiative, and get a nice sorted list of combatants. Keep track of turns, and process damage and healing with super quick data entry shortcuts. Minimal taps required. This is the fastest and easiest combat / initiative tool there is! --[FREE] When combat is done, reset and record the battle in your campaign journal so you can have a nice history of what went down at the end of the night. Add manual journal entries any time you like. --[FREE] Name Generator - Quick way to produce a name for a NPC on the fly. You can quickly add it to the journal, too, so you can remember that bartender's name later. --[FREE] Reference - All the things you need to look up in the middle of your session. Much easier than paging through the books for these frequently used items. Ability checks, equipment stats, feats and backgrounds, combat actions, conditions, creature types, damage types, schools of magic, spellcasters guide, etc. --[FREE] Monster Lookup - Quickly look up monsters and stats in the Basic Rules (network connection required). Paid subscribers can also add them to your combat encounter. --[PAID] NPC Creator - Maybe the coolest thing you've seen in a while, tap on the attributes for a quick encounter (Dwarven Rogue Level 5, or Forest Monster CR 5 - CR 10) and you'll get a name and background made for you in seconds. --[FREE] Sound Effects - Play built-in background loops and sound effects to enhance the ambiance, and easily link to your own music library playlist for quick access. --[FREE] Images - Several dozen characters of various classes and species, and monsters to show your players. You can also do an image search to quickly find any of thousands of monsters on the internet. [PAID] You can even upload the images to your Discord channel. [PAID] Nothing could be easier and faster! --[PAID] Multiple campaigns are supported, so you can have all your PC's, NPC's, and journals organized by campaign. --SUBSCRIPTION REQUIRED FOR SOME FEATURES. New subscribers get a free trial period before any charges are made, so you can see if it's worthwhile for you. Even more features are coming!
