The game#
| Term | Meaning |
|---|
| 3.3.5a | The last patch of Wrath of the Lich King's original release (2010). The client and server engine the project runs on. |
| WotLK Classic | Blizzard's 2022–2024 re-release of Wrath of the Lich King. Its final state, Season 8, is the ruleset the project aims at. |
| Season 8 | WotLK's last arena season. Its gear is Wrathful Gladiator's. |
| Arena | Small team deathmatch: 2v2, 3v3 or 5v5 (only 2v2 and 3v3 here), on a small map with pillars to break line of sight. |
| Comp | A team's composition of classes and specs, such as Rogue / Priest. The unit the project trains. |
| RMP | Rogue, Mage, Priest: the classic 3v3 comp, and the project's first. |
| Loadout | One character's spec, talents, glyphs and gear, stored as data. |
| 264 meta | The gear baseline: Wrathful items plus PvE items up to item level 264. See the 264 meta. |
| ilvl | Item level: a rough measure of an item's power. |
| Resilience | A PvP stat that reduces critical-strike chance and damage taken. |
| CC | Crowd control: stuns, fears, polymorphs and the like, which stop a player acting. |
| DR | Diminishing returns: each repeated CC of the same category lasts half as long, then a quarter, then the target is immune until the category resets. |
| LoS | Line of sight. Most spells need it; pillars block it. |
| Dampening | An arena aura that cuts healing and absorbs by 10%. |
| Trinket | The PvP trinket that breaks crowd control, on a long cooldown. |
| Interrupt, kick | Stopping an enemy's spell mid-cast, which also locks that school of magic for a few seconds. Players call it a kick after the rogue's Kick. |
| Global cooldown, GCD | A lockout of about 1.5 seconds after most spells. Interrupts, the PvP trinket and many defensive spells skip it. |
| Instant | A spell with no cast time, castable while moving. |
| Macro | A short script on one key, such as casting several spells that skip the GCD. |
| Addon | A player-installed interface extension: it shows, never acts. |
| Unit frames | Panels with the health, buffs and casts of you, your target, party and enemies. |
| Nameplate | A health bar over a unit within 41 yards, shown through pillars. |
| Combat log | The client's running record of hits, heals, casts and effects. |
| Totem | A small object a shaman places, with its own effect and health. |
| Hub | The small area where human players arrive and queue. See the server. |
Emulation#
| Term | Meaning |
|---|
| AzerothCore | The open-source WotLK server emulator the project runs, pinned to one version. |
| Module | The project's own server code, kept apart from AzerothCore's. Fixes and features live there. |
| DBC | The client's data tables: spells, items, talents. Compared against the server to find differences. |
| Headless client | A program that speaks the 3.3.5a protocol like a real game client, with no graphics. Tests use them as players. |
| The gate | The full live-server test suite, run weekly on the live server. |
| Lead | A place where the server may differ from the real game, raised by any source. A question, not evidence; getting the game right. |
Agents#
| Term | Meaning |
|---|
| Game agent | The trained player. Not to be confused with the AI agents that build and run the project. |
| Parity | The rule that agents perceive and act only as a human could. See human parity. |
| Perception layer | The one place where the game state is reduced to what a player could know. |
| Agent interface | The single observation and action format every agent uses. |
| Scripted baseline | A hand-written agent per comp: the first opponent, and the fixed yardstick for progress. |
| Anchor | A fixed agent whose rating is held constant, so ratings stay comparable. |
| Measurement era | A period with one fixed set of parity and measurement settings. Ratings compare only within one era. |
| Virtual clock | Running the real server faster than real time, for matches with no humans in them. |
| Tick | One pass of the game server's main loop, moving every player, spell and timer forward. See server speed. |
| Self-play | Agents training by playing other versions of themselves. |
| Policy | The part of a trained agent that picks each action from what it observes. |
| Rung | One small experiment on the research ladder, assuming only what earlier rungs settled; learning to move. |
The project#
| Term | Meaning |
|---|
| The owner | The one person behind the project. Sets the premises and may steer; runs nothing day to day. |
| The box | The isolated container agents work in. See the walls. |
