TFT Terminology: 40+ Slang Terms and Acronyms Explained
A grouped TFT glossary explaining rolldown, tempo, cap, BIS, pivot and 40+ more slang terms so you can look any of them up mid-game.
You are two rounds from a rolldown, someone in chat says the enemy is hard capped, and a guide keeps telling you to slam BIS and hold tempo. If half of that sounds like a foreign language, you are not alone. This TFT terminology reference collects the tft terms, tft slang, and acronyms you actually hear in ranked lobbies and on stream, grouped by theme so you can find the one you need without breaking your concentration. Treat it less like an article to read front to back and more like a tft glossary to keep open in a second tab.
Economy Terms Every TFT Player Should Know
Economy is the engine of the game, and it has the densest slang. Almost all of it circles one idea: gold you hold generates interest, so spending too early can cost you far more than the units you buy. Get comfortable with the words below and the difference between a good game and a bricked one becomes obvious in real time.
| Term | What it means |
|---|---|
| Econ / Economy | How you manage gold overall. "Playing econ" usually means saving to hit interest and level rather than spending on units now. |
| Interest | Passive gold you earn each round, +1 gold per 10 saved, capped at +5. Crossing 10/20/30/40/50 gold is the whole point of saving. |
| Roll / Rolling | Spending 2 gold to refresh your shop. You roll to find and upgrade specific units. |
| Rolldown | Dumping a big chunk of gold at once to find your units, usually right after hitting a target level. The most decision-heavy moment of most games. |
| Slow roll | Staying at one level and spending only the gold above 50 each round, so you keep max interest while fishing for 3-star units. |
| Hyper roll / Fast level | The opposite plan: level aggressively and roll early to overpower the lobby before others stabilize. |
| Fast 8 / Fast 9 | Rushing to level 8 or 9 as quickly as possible to access the strongest units, often at the cost of health. |
| Win streak / Loss streak | Consecutive wins or losses. Both grant bonus streak gold, so committing hard to one or the other beats flip-flopping. |
| Open fort | Intentionally selling your board to lose on purpose, preserving gold and streak while taking minimal damage from a weak fight. |
| Greed / Greedy | Pushing econ or a stronger comp at the risk of your health. Sometimes correct, often how players die at 20 HP with a full bench. |
| Stabilize | Reaching a board strong enough to stop the bleeding after a rough stretch. |
Combat and Board Terms
This group describes what happens once the round starts and you can no longer touch anything. A lot of newer players obsess over which units they own and ignore how those units are arranged, which is backwards. Your frontline soaking damage while a defended carry deletes the enemy is the entire game plan in three words.
| Term | What it means |
|---|---|
| Carry | The unit meant to deal most of your damage. It gets your best items and your most protected position. |
| Tank / Frontline | Durable units placed on the front rows to absorb damage and stall while the carry ramps. |
| Backline | The rear rows where squishy carries and casters live, out of reach of most melee. |
| DPS | Damage per second. A carry's job description. |
| CC | Crowd control: stuns, knockups, silences, anything that stops enemies from acting. Wins fights more than raw damage. |
| AoE | Area of effect. Damage or CC that hits multiple units at once, punishing clumped boards. |
| Mana-lock / Mana gate | A unit stuck unable to cast because it can't gain mana, usually from being CC'd repeatedly. |
| Shred / Sunder | Reducing enemy magic resist (shred) or armor (sunder) so your damage lands harder. |
| Tempo | Being ahead of the lobby's curve right now. High tempo means you can level or econ while others struggle to keep up. |
| Board strength / Board state | How strong your current eight-or-fewer units are compared to the rest of the lobby. |
| Positioning | Where you place units on the hex grid. Adjusting it between rounds to dodge assassins or bait CC is free win percentage. |
| Scaling | How a unit or comp grows over a fight or over the game. "Scaling carries" are weak early and terrifying late. |
Items and Itemization Slang
Items decide more games than unit tiers do, and the vocabulary around them trips people up because it mixes acronyms with community shorthand. The single most important habit is item slam: taking a strong completed item like a Deathblade or a Warmog's Armor and putting it on a reasonable holder now, instead of hoarding components for a perfect build that may never arrive. A slammed Bramble Vest keeping you alive this turn beats a theoretical Guinsoo's Rageblade you build on turn 30 after you've already lost.
| Term | What it means |
|---|---|
| Component | The basic item pieces (like a sword, bow, or belt) that combine into completed items. |
| Completed item | Two components merged into a finished item with its full effect. |
| Item slam | Building and equipping a strong completed item early rather than saving components for a perfect fit. |
| BIS | "Best in slot." The ideal item set for a specific carry. A goal, not a requirement to hit before you can win. |
| Itemize | The act of deciding which items go on which units. |
| AD / AP / AS | Attack damage, ability power, attack speed. Shorthand for what a carry scales with, which tells you what to build. |
| Sustain | Healing or shielding that keeps a unit alive, like omnivamp or a Warmog's-style health item. |
| Emblem / Spat | An item that grants a unit an extra trait. "Spat" refers to the rare component used to make many of them. |
| Support item | Team-buffing items that don't need a carry, often given out through special mechanics rather than built from components. |
| Radiant / upgraded item | A supercharged version of a normal completed item, usually offered by a special mechanic. |
| Overcapping items | Stacking so much of one stat (often attack speed) that extra copies are wasted. A reason not to force every good item onto one unit. |
Strategy and Meta Terms Explained
This is the highest-level tft terminology, the words coaches use to describe plans rather than mechanics. The theme here is flexibility. The best players read what the game hands them and adapt, so most of these terms are really about choosing, contesting, or abandoning a direction at the right moment.
| Term | What it means |
|---|---|
| Comp | Composition. The specific set of units and traits you're building toward. |
| Vertical | Stacking many units of one trait to hit its highest breakpoint, like going deep into a single origin. |
| Splash | Adding one or two off-comp units purely to activate a small trait bonus. |
| Flex | Playing your board loosely so it can become several different comps depending on what you find. |
| Force / Forcing | Committing to one comp from the start regardless of what you're offered. Reliable to learn, risky when contested. |
| Pivot | Switching comps mid-game because your first plan isn't coming together or is heavily contested. |
| Contest / Contested | When multiple players want the same units, thinning the pool so nobody 3-stars easily. Reading contest is a top-tier skill. |
| Cap / Capped board | The strongest possible version of your board. A "hard cap" is your ceiling if everything goes right. |
| 1/2/3-star | A unit's upgrade level. Combining three copies makes a 2-star; three 2-stars make a 3-star, a huge power jump. |
| High roll / Low roll | Getting lucky (high roll) or unlucky (low roll) with shop offerings and drops. |
| Reroll comp | A comp built around 3-starring cheap units, funded by slow rolling at a lower level. |
| Meta / Off-meta | The comps most players consider strong right now (meta), versus everything else (off-meta). |
| Tier list | A ranking of comps or units by strength. Useful as a starting point, dangerous as a script. |
| Standard | The default, level-and-play-strongest-board approach, as opposed to a dedicated reroll or hyper-roll plan. |
- Early gameStreak and slam
Play your strongest board, commit to a win or loss streak for the bonus gold, and item slam anything that keeps you healthy. Don't force a final comp yet. Stay flex and read what units are open in the lobby.
- Mid gameLevel and stabilize
Push levels on tempo or slow roll for a reroll comp. This is where you decide to commit or pivot based on contest. A clean rolldown here to stabilize is worth more than clinging to interest while your health drains.
- Late gameCap the board
Fast 8 or fast 9, roll down for your strongest units, and chase your capped board. Positioning, shred, and CC decide fights here far more than one extra item does.

Guide FAQ
What is a rolldown in TFT?
A rolldown is when you spend a large amount of gold refreshing your shop in a short window to find and upgrade specific units. Players usually rolldown right after hitting a key level, when the odds of seeing the units they need spike. It's the single most decision-heavy moment in most games, so plan which units you're hunting before you start clicking.
What does BIS mean and do I need it to win?
BIS means "best in slot," the ideal item set for a given carry. You do not need it to win. Treat BIS as a target you drift toward, not a gate you must clear before committing. Slamming roughly the right stat early and staying alive wins more games than waiting for the perfect three-item build.
Slow roll vs fast 8, which is better?
Neither is universally better; they suit different comps. Slow rolling stays at one level and spends only excess gold to 3-star cheap units, so it shines with reroll comps. Fast 8 rushes to high levels for premium units and works when your carries live at 4 or 5 cost. Pick based on where your comp's power lives, not habit.
What does it mean when a board is "capped"?
A capped board is the strongest possible version of your comp if everything goes right, the correct units at the right star level with ideal items and traits. A "hard cap" is your ceiling. Knowing your cap tells you whether it's worth pushing greedy for more or safer to stabilize and take a solid placement now.
How do I learn TFT terminology faster?
Keep this tft glossary open while you watch a stream or read a guide, and look up terms the moment they appear instead of guessing. The tft slang sticks far quicker when you attach each word to a real board you're looking at. Within a few games, econ, tempo, pivot, and slam will feel like second nature.
What is tempo and why does everyone talk about it?
Tempo is being ahead of the lobby's curve right now, usually through a win streak or an early power spike. When you have tempo you can level or save gold while opponents are forced to roll and spend, which compounds your lead. Losing tempo is why players fall from first to eighth, so protecting it is a core strategic goal.
