How to learn TFT Set 18 comps without memorising a single list

A new set means a whole library to relearn: new units, new traits, a brand-new set mechanic, and that very specific feeling of not knowing what to buy on the first shop. Set 18, opened by patch 18.1 (the same patch that moves Teamfight Tactics onto Unreal Engine and removes macOS support), is no exception. The good news is that you do not learn a set by memorising unit lists. You learn it by knowing how to read what the client already puts on screen, and that skill works on day one as well as three months in.

What a new set changes, and what stays put

• Almost every unit changes: names, costs, abilities, range, role on the board.
• Traits change too: their breakpoints, and above all what they hand you once active.
• The set mechanic changes: it is the rule specific to the set, and it shapes how games play out.
• What does not change: gold interest, level thresholds, carousels, item components, the logic of positioning.
• What does not change either: your account, your rank and your collection, all carried from one set to the next.

In other words, the foundation is untouched. If interest, level thresholds or item recipes are still fuzzy, start with our beginner guide to Teamfight Tactics: those rules outlive every set, and they matter far more to your rank than knowing this week’s trendy comp.

Read the trait panel before you look for a list

The game already gives you everything you need. Before your first game of the set, open the trait panel in the client and read it like a map rather than a catalogue. Five passes are enough.

1. 1Spot the traits with low breakpoints (two or three units): those activate early and carry the opening rounds.
2. 2Spot the traits with high breakpoints (six units and up): those are endgame targets, not opening plans.
3. 3For each trait, note whether it protects (resistances, healing, shields) or kills (damage, attack speed). A comp needs both.
4. 4Look for units carrying two useful traits at once: they are the backbone of most comps.
5. 5Check the cost of each trait’s key unit. A trait built on four or five cost units is not played at the same level as one built on one and two cost units.

That read takes ten minutes and replaces hours of video. More importantly, it gives you what a ready-made list never will: something to improvise with on the day the shop refuses to cooperate.

The three comp families every set has

The names change every set, the families do not. Every Set 18 comp falls into one of three buckets, and knowing which one you are playing beats knowing thirty lists by heart.

The low-cost reroll

You deliberately stay at a low level, keep your gold just above the interest threshold, then spend it all at once to turn one, two or three cost units into three-star versions. The board is strong very early and steals rounds while everyone else is still building. The known weakness: it caps out. If the three stars arrive late, the endgame hurts.

The standard level 8 comp

This is the default plan and the most forgiving one: level steadily, stabilise around level 8, and assemble four cost units around a single item holder. It asks for few gambles, bends to whatever the shop offers, and remains the best choice while you are still learning a set. Early in Set 18, treat it as your baseline.

Fast 9 and legendary units

You sacrifice the mid-game rounds to hit level 9 as early as possible and field five cost units. It is the most gold-hungry and the riskiest plan: it assumes a real economic lead or a comfortable health bar. Attempted without either, it ends in seventh. During the first days of a set, it is rarely the right instinct.

Pick your comp from what the game hands you

The most common early-set mistake is deciding on a comp before the first shop, then clinging to it no matter what. Yet the components you grab on the opening carousel, the units the shop actually offers, and the ones the other seven players leave alone all arrive after that decision, and they matter far more than the plan you walked in with.

The method that holds up starts from items. Three defensive components point to a tanky holder that soaks damage; three offensive components point to a damage carry. Only then do you check which Set 18 trait fits that holder, and which units the shop is actually giving you. You commit for real around the mid-game, not on round one.

A flexible player who finishes fourth every game climbs faster than one who forces a favourite comp and alternates firsts with eighths.

A five-step routine for the first days of a set

1. 1Play two or three games with no rank on the line, purely to watch the new units fight.
2. 2Pick two comp families (a reroll and a level 8 plan, say) and stick with them for a handful of games.
3. 3After every loss, ask one question only: did I lose on economy, on items or on positioning?
4. 4Change one thing in the next game. Two changes at once teach you nothing.
5. 5Wait a week before calling a trait weak. The first days reward players who already know the game well.

Balance patches in the opening weeks move the goalposts often: what dominates on Monday can be nerfed by Wednesday. Better to own the method than a list. For what this set launch contains and what it changed platform-side, our patch 18.1 breakdown covers the ground.

Classic early-set mistakes

• Copying a comp without checking whether three other players are already contesting its key units.
• Forcing a high-breakpoint trait when the game is giving you neither the gold nor the units to reach it.
• Dropping below the interest threshold for a reroll that was not urgent.
• Sitting on a bench full of units you will never play instead of selling them to level up.
• Fielding the same formation eight rounds in a row. The opponents change, so should your positioning.

On a Mac, Set 18 runs through the Android build

One thing to know before diving into the new set: patch 18.1, the very patch that opens it, removes macOS support. Since the move to Unreal Engine, Teamfight Tactics is neither supported nor patched on that system. Riot frames the removal as temporary and says it is working to support macOS in a future update, with no date announced. Nothing happens to your account: progress, rank, collection and purchases stay tied to your Riot account.

The Android build, meanwhile, keeps being developed and updated normally, with the same Set 18, the same traits and the same ranked ladder used on EUW and NA. That is the build running inside OSFT Launcher on Apple Silicon Macs, full screen and on a keyboard. It matters while learning a set: rebinding reroll and buy XP changes how many attempts you fit into a planning phase, and our Mac keyboard controls guide walks through it.

Frequently asked questions

In short

Learning Set 18 is not about memorising lists. Read the trait panel, recognise which of the three comp families you are playing, and start from your items rather than a plan chosen in advance, and top four placements follow. The rest comes with games played. And on a Mac, where the set now runs through the Android build since macOS support was removed, a well-tuned keyboard simply buys you more attempts per planning phase.
