What a combo actually is
A combo — or lineup — is simply the set of heroes you deploy together in a battle. Because their skills fire in the same fight, the useful question is never "which single hero is strongest" but "which heroes make each other stronger." A lineup where three heroes' skills chain together — one opens with crowd control, another amplifies the damage that lands, a third keeps the group alive long enough to finish the job — will reliably beat three unconnected heavy hitters who each do their own thing.
That is the whole idea behind a combo: the heroes are chosen for how they combine, not for their individual rankings. This is also why copying a top player's exact lineup rarely works if you swap one hero for a "similar" one — you can break the chain that made it good in the first place.
Why synergy beats raw stats
It is tempting to build around your single highest-Might hero and fill the rest of the slots with your next-biggest numbers. Might, though, is mostly a measure of how much you have invested in a hero — level, gear and skill upgrades — not a measure of how well that hero fits a lineup. A heavily invested hero with no synergy partners will often contribute less than a modestly developed hero slotted into a combo built around them.
This is exactly why some individually powerful heroes appear in surprisingly few top-ranked combos, while a few unassuming heroes turn up again and again: their skills are the glue that holds strong lineups together.
The four combo categories
Every combo on ROCMeta sits in one of four categories, and each holds an explicit rank within that category, from #1 downwards:
- Cavalry combos — lineups built around mounted troops, usually fast and aggressive.
- Archer combos — lineups that lean on ranged damage from the back line.
- Footmen combos — durable, front-line lineups that hold ground and absorb pressure.
- Mixed combos — lineups that deliberately blend troop types to cover more situations at once.
Grouping combos this way matters because your account usually leans toward one troop type. If most of your investment is in cavalry heroes, the Cavalry rankings are the list to read first.
"The best combo" vs "the best combo you can build"
Most combo guides show you the strongest lineups in the game. That sounds helpful until you notice the #1 combo needs three heroes you do not own — at which point the ranking is useless to you. The combo that wins your next battle is the best one you can actually field today, and that depends entirely on your roster.
That is the problem this whole site is built to solve. Instead of memorising a tier list, you tell the Combo Generator which heroes you own and it shows you the ranked combos you can field right now, the ones you are one or two heroes away from, and the single hero that would unlock the most new combos if you invested in them next.
Where the rankings come from
Nothing here is placed by hand. Every combo's score is computed from the heroes' own skill text as written in the game — expected damage, trigger chains between the three kits, the row each skill's range allows, troop eligibility and season strength — and the order of the list is that score. Community usage and the game's own in-game recommendations are used only to test the model, never as inputs. The eleven checks and their point values are set out in full on the methodology page. When a ranking moves, it moves for a stated reason.
