## What it is
DiIiS (Blizzless) is a fully-functional open-source server emulator for Diablo III: Reaper of Souls, written in C# on .NET. It implements accounts, lobby, chat, clans, dungeon generation, itemization, quest and adventure-mode scripting, and monster AI, backed by PostgreSQL.

## Use cases
- host a private Diablo 3 server for LAN play
- run a local Diablo III: Reaper of Souls server emulator
- play Diablo 3 offline with friends on a self-hosted server
- set up a private server with account creation and clans
- test Diablo 3 game mechanics on an open-source server

## When to choose
- you own Diablo III 2.7.4.84161 and want a self-hosted server
- you want LAN or private multiplayer without official Battle.net
- you want to study or contribute to game server emulation in C#

## When to avoid
- you want a turnkey legal online service - emulating Blizzard servers may violate ToS
- you need a newer client version than 2.7.4.84161
- you need production-grade scalability or donate-store features

## Facets
- artifact type: application
- maturity: active
- function: game-engine, networking, auth, database
- domain: gaming-tools, self-hosted
- platform: windows, self-hosted, dotnet
