Hero-collecting RPGs hand you dozens, sometimes hundreds, of characters and then ask you to choose five or six. Most newcomers make the same two mistakes: they chase the characters that look strongest, and they spread upgrade materials across everyone they like. Both habits lead to a roster of half-powered heroes that stalls at the first real difficulty wall. This guide explains how teams actually work in these games, using examples from the titles in our directory, so you can build something sturdier from your first week.
Almost every team-based RPG sorts characters into a few jobs, even when the labels differ:
A team with one of each, or at least a tank, a healer and two damage dealers, is usually more reliable than a team of five attackers. When a stage feels impossible, the cause is more often a missing role than a missing level.
Characters rarely work alone. Many games reward pairs or groups: a hero who applies a status effect next to one who deals extra damage to afflicted enemies, or characters from the same faction who unlock a shared bonus. When you read a hero's skill description, ask two questions. What does this need in order to work, and who in my roster provides it? A mediocre-looking unit that completes a combination can outperform a famous one that has no partner.
Upgrade materials are always limited, so where you spend them matters more than how much you have. A sensible order for most games is:
Resist the urge to level every new character "just in case". Many games let you replace a character later, but materials already spent are gone.
The same principles show up in different forms across our directory, which is a good way to see what to look for:
In games with a front row and back row, fragile attackers behind sturdy defenders is the default arrangement. If your damage dealers keep dying first, they are probably too far forward or your tank is too weak. If fights take too long, you may have too many defensive units and not enough damage. Adjust one thing at a time so that you can see what changed.
When you get stuck on a stage, resist the urge to grind blindly. Look at how you lose. If your team dies in the first few seconds, you need more survivability. If you survive but cannot finish enemies, you need more damage or a way to deal with a specific trait such as shields or high speed. If the fight is long and close, small upgrades or a better formation may be enough. This kind of diagnosis saves far more time than simply levelling everything again.
Most hero-collecting RPGs use random summons to hand out new characters. Because results are random, treat each draw as entertainment, set a limit before you start and remember that a well-built team of ordinary characters beats a collection of strong ones with no plan. Our guide to reading Play Store ratings explains how to check whether a game's monetisation draws heavy complaints before you commit.
Far fewer than the roster suggests. A reliable core of four or five characters, upgraded steadily, usually carries you further than a large collection spread thin. Add more only when a particular stage demands a different role.
It depends on the game. Auto-battle is useful for repeating stages you can already clear. For new or difficult content, manual control of timing and positioning can make a large difference, so use it when you are trying to progress.
Some games allow it and some discourage it in their terms of service. Check the game's rules before creating extra accounts, and remember that a good team comes from planning more than from luck.
