Roguelikes have a language of their own. Whether you are diving into Hades, building game-breaking decks in Balatro, or trying to survive Dead Cells, the genre is packed with jargon, mechanics, and design concepts that every player encounters.
Here is the definitive dictionary - every term you need to know to speak the language of roguelikes.
Section 1: The Core Fundamentals
1. Roguelike
A genre named after its founding father: the 1980 classic Rogue. Traditionally, a true roguelike features grid-based movement, turn-based combat, procedural generation, and strict permadeath with zero persistent upgrades. Examples include classics like Caves of Qud and Tales of Maj'Eyal.
2. Roguelite
A subgenre - or derivative - of roguelikes. While the two terms are often used interchangeably today, roguelites tone down the strict punishment of the original genre by introducing persistent progression. When you die here, you don't lose everything.
3. Run
A single, complete attempt at the game - from the moment you press "Play" until you die or reach the end credits. Thanks to randomized elements, no two runs are ever identical. Between runs, you’ll usually hang out in a customizable hub or menu to prepare for your next try.
4. Permadeath
Short for permanent death. When your health hits zero, the run ends on the spot - there are no checkpoints or quick loads. Everything you collected during that specific attempt - weapons, gold, items, and temporary buffs - is wiped out, and you’re sent straight back to square one.
5. Meta-progression
Simply put, it’s everything you don't lose upon death. Whether it’s permanent stat upgrades, new starting weapons, or expanding the overall item pool, meta-progression ensures that every failed attempt still moves you forward.
Section 2: The World & Randomness
6. Procedural Generation (Proc-Gen)
Instead of hand-crafting every level, the game uses algorithms to randomly construct map layouts, enemy spawns, and chest placements every time you start a run. It’s the secret sauce behind infinite replayability.
7. Seed
The unique string of numbers and letters that governs the game's procedural generator. Sharing a seed with another player lets them play on the exact same map layout with the exact same item drops, removing the element of random chance for competitive or casual comparisons.
8. Biome
The distinct zones or stages of a run, each with its own visual theme, unique enemy types, environmental hazards, and boss at the end (such as moving from the Prisoners' Quarters to the Promenade in Dead Cells).
9. Node / Pathing
The branching path system on a run map. Choosing your nodes carefully lets you balance risk and reward - deciding whether to hunt for loot in elite fights, heal at a camp, or visit the shop.
10. Rest Site / Campfire
A safe node or room on the map where combat is paused, giving you a crucial tactical choice - usually between recovering missing health or upgrading an existing card, skill, or weapon.
Section 3: Builds & Mechanics
11. Build
The specific combination of items, weapons, abilities, and stat boosts you assemble during a single run. A good build synergizes well; a bad build gets you killed early.
12. Synergy
When two or more items, relics, or abilities interact with each other to create an effect far more powerful than the sum of their parts. Finding crazy synergies is usually where the real magic of roguelikes happens.
13. Relic / Artifact
Passive items that grant permanent bonuses or unique mechanical effects for the remainder of your current run. Unlike weapons or active skills, relics usually work in the background without needing to be manually activated.
14. Consumables / Items
Single-use items or active tools with limited charges that provide an immediate benefit - like restoring health, dealing instant damage, or granting a temporary buff during a tough fight.
15. Drafting
A mechanic borrowed from card games where you are presented with a random selection of choices - usually three - and must pick one to add to your build while discarding the rest.
16. RNG (Random Number Generation)
The metaphorical "god of chance" in gaming. RNG dictates what loot spawns, what enemies appear, and whether luck is on your side during a run.
Section 4: Encounters & Progression
17. Shopkeeper
An NPC store owner encountered during a run who sells items, healing, relics, or upgrades in exchange for gold or other temporary run currency (e.g., Charon in Hades or the Merchant in Slay the Spire).
18. Random Event
A randomized narrative encounter or shrine where players must make a high-risk, high-reward choice - such as sacrificing health for a powerful relic, or gambling gold for a mystery reward.
19. Buff & Debuff
A buff is a temporary positive effect on your character (like increased movement speed or attack damage). A debuff is a negative status effect applied to you or an enemy (like bleed, poison, slow, or defense reduction).
20. Drop Rate
The percentage chance that a specific item, enemy, or piece of loot will appear when a chest is opened or a monster is defeated.
21. Elite Enemies
Tougher, empowered variants of regular monsters with larger health pools and unique dangerous traits. They pose a high risk of ending your run, but beating them guarantees high-tier rewards like relics or rare weapons.
22. Boss & Mini-Boss
Major skill checks encountered at key points in a run. Mini-bosses guard elite rewards during a level, while main bosses act as gatekeepers at the end of every biome.
Section 5: End-Game & Meta
23. Looping
A mechanic that allows you to skip the ending after defeating the final boss and restart the run from Stage 1 - keeping your entire endgame build, but facing drastically scaled-up enemy difficulty.
24. Ascension / Difficulty Modifiers
Post-game difficulty systems that unlock after your first successful victory (such as the Heat gauge in Hades or Ascension levels in Slay the Spire). They allow players to stack negative modifiers - like stronger enemies, higher shop prices, or lower healing - to test their skills on increasingly brutal runs.
25. Unlockables
Content locked behind specific achievements or progress milestones. Completing challenges unlocks new characters, weapons, or relics, permanently adding them to the item pool for all future runs.
26. Daily Run / Challenge Mode
A special game mode that resets every 24 hours. Every player around the world gets the exact same seed and forced mechanical twists, competing for the highest score on a global leaderboard.
27. True Final Boss / Secret Floor
Hidden endgame content accessible only by completing specific, obscure tasks during a run (like collecting hidden keys or beating a boss within a strict time limit). These areas contain the game's hardest challenges and true narrative endings.
