Introduction

Our D&D 5th Edition combat simulator provides Dungeon Masters with tools to balance combat between Player Characters and Monsters.

The goal of of the combat simulator is to use AI/Machine Learning with 5e rules to

• a) Help with encounter design demonstrating how battles look over multiple encounters video.
• b) Help creating competitive games even on short notice that dont accidentally kill everyone in the first fight.
• c) Managing complex larger scale battles.
• d) Testing and optimizing characters or home brew monsters you could only theory craft about

The Encounter builder lets a DM create modules with many chapters and encounters.
Any encounter can be loaded into the Combat Tracker for the DM to manage complex battles, especially with remote players.

We have more exciting tools and games planned for the future... ! Jump to D&D maps

What does the D&D combat simulator do

• 0. Import your D&DBeyond characters (3 min how to video) or create manually with templates.
• 1. Build a D&D 5th ed. encounter between player characters and monsters.
• 2. Click fight.
• 3. See who won, who wins on average, who might not survive, and just how hard the fight is.

Multiple fights/day. use Encounters to build multiple groups of monsters to simulate for example the party fighting one, short rest before fighting the next etc.

Ultimately as a DM you will be able to build out all your encounters for a module or session and with a click see how they will fair on average!

Disclaimer Most real players will be smarter than the computer but you can use this to challenge them with close fights.
Some groups are designed more for role playing than battle and so you can make sure that you are not going to accidentally kill them all!

What you do

• Search for PCs. On the New Fight page search by name or class and click on the green icon to add to the PARTY side.
• Search for Monsters. Repeat the search and click the red icon to add to the MONSTERS side.
  Note you can add players to the monsters side for PvP or monsters to the players side using the smaller or button
• Start the fight. Click the Execute 25 fights button to generate a sample fight (with a grid) as well as statistics for who is winning or dying on average.
• View the results. Click the Simulator tab to view the results.  On the first page you have the %won by players and more information.
  Use the scroll bar to go from round to round on the sample fight. The last page has additional statistics

What it did

• Rolled dice. the simulator is rolling random dice to hit and do damage.
• Cast spells. spells or class features are used and the resulting damage or inflicted condition is recorded round to round.
• This is NOT Theatre of the mind. Each creature has coordinates, move speed and the
  AI
  decides on its movement (e.g. dash) each round.
  Distance is measured against the range of spells and physical attacks.
  A grid is used for area of effect spells
• Prioritized actions. While still a work in progress, the software decides whether to attack, or heal someone or cast a particular spell.
  It executes bonus actions and lair actions and legendary actions - whatever is need for the fight.

What you can store

• Compendium. If you register/log in you can save your PCs or create your own home brew monsters.
• Spellbook. Similarly you can create your own spells, feats, features, and magic items to represent your party.
• Modules. You can create individual encounters (a fight) and group those into modules so you can test how back to back fights hurt the party

What it is not

• Character Build Assistant. You will need the Players Handbook in order to determine the correct values.
  However you CAN create characters, even with UTF support e.g. 龙与地下城
• VTT. Despite playing around with some minor VTT features, if you are looking for some serious virtual table top software check out https://foundryvtt.com/

What is not finished

• Content. You can see the %complete in the menu, still a large number of spells, class features, magic items and monsters to add !
• Functionality. From user interface enhancements to finishing full module back to back fights with levelling up, treasure in between encounters, still lots to do.

What is in store for the future

• Machine learning. The code which picks the best action is very simple but in the future it will be highly competitive.
• Interactive battles. First step is to be able to walk through the simulation step by step so that you can make changes along the way.
  Second step is to be able to run the battle online with a friend.
• Upload maps. Being able to upload a map and decide on the starting positions would be great.
• Wargames. Imagine being able to conduct a massive battles with hordes of demons fighting the legions of hell while your players characters are beset on all sides!

Why Dungeons & Dragons

The year was 1982. I was 11 years old at a boarding school in England. I had borrowed a copy of Basic Dungeons and Dragons after seeing some of the older kids playing. I drew my first dungeon, a series of tunnels with caves that contained monsters and little more than a one line description. The following night I took a class mate through the adventure. We were hooked by the excitement of battling for glory and plundering the caverns for treasure.

While I didn't play D&D again in the 80s I do remember playing Tunnels and Trolls and avidly reading (playing) the Fighting Fantasy books. 1989 - 1992. Glory years of our FR campaign The greatest campaign in the history of Faerun with legends such as Athelstan (Holiest of Paladins) Leyden (Elven Fighter RIP 1991) Koric (Figher/Mage/Psionisct) Careb (Elven Fighter - Dual Longswords) An arch mage turned Lich (shall not whisper his name)

2020 - present. With the outbreak of the Coronavirus it felt like a good time to relive the nostalgia of playing Dungeons & Dragons so I picked up the 5th Edition Players Handbook, Monster Manual and Dungeon Masters guide. Compared to 2nd Edition I realized how far game design has come and with mounting excitement wanted to write glorious adventures again that the world can enjoy.

Back in the day I would always carefully plan the final battle between my powerful player party of 6-8 and my villains. This grew more and more complex as the group levels became higher and higher. In general I calculated the damage output and hit points pool of either side, accounting for spells and magic items. I aimed to make it 50-50 because they were very strategic. This was done with a pencil and paper.

Now, 20 years later, with a computer science degree it is time to do the real deal and have the software simulate the battle, and not just one battle, all the battles. This is possible because the 5th Edition rules are very well designed. SO LETS GO !
