Arena team guide: winning 3v3 battles

What actually decides a fight?

Stats first, types second, luck third. A team with clearly higher stats wins even into a bad type matchup, so raising your Cromons matters more than any clever pairing: mint stronger ones through Rifts, add permanent stats with Cromite from The Deeps, or merge duplicates at the Fusion Forge. The type chart earns its keep between evenly matched teams: that is where the 1.5x swing turns a coin flip into a win.

How should I use the type chart?

Cover, do not stack. Three Cromons of the same element all share the same weakness, so one bad matchup loses the whole fight. Spreading two or three elements across the team means at least one of your fighters usually hits favorably. The chart works both ways: if Fire hits Grass at 1.5x, Grass hits Fire at 0.75x. The full chart lives in the types and rarities guide, and the starter trio (Fire, Aqua, Grass) is already a working example of coverage.

How do attacks, defense and rating work?

You attack with a team you pick per fight, and you set a separate defense team that other Keepers challenge while you are away. Losing a defense costs a little rating, nothing else. Every attack costs 1 Aether, matchmaking offers rivals near your leaderboard rank, and wins raise a persistent rating: there is no seasonal reset, so progress sticks. Wins also pay XP toward your Keeper level, capped at 1,500 XP per day.

What does a good session look like?

Short and regular beats marathon. Aether refills over time, so a few fights per visit keeps you climbing without waiting on an empty bar. Between sessions, keep your roster working: miners in The Deeps earn the Cromite that makes next week's team hit harder, and an Expedition pays for the upgrades. Just remember a Cromon on a lane or a mission is busy: keep three fighters free for the Arena.

How do the rolls read your stats?

Every outcome in a fight is a stat divided by a fixed number, so each point has a known price. A Cromon's HP is 80 plus 4 per point of its HP stat, from 92 to 200 before Cromite. A critical hit doubles the damage and its chance is the Critical stat divided by 100, capped at 30%: a 30 Critical fighter crits almost one hit in three. A block is Defense plus Resolve divided by 400, capped at 20%, and lets only 40% of the hit through; a dodge is Speed divided by 200, capped at 20%, and lets nothing through. Every attack also carries a fumble chance that shrinks with Critical, never below 2%, dealing nothing and recoiling a quarter of the damage onto the attacker. Read that way, Critical is the best offensive point you can add, Speed the best defensive one, and HP the stat that lets a slow tank outlast a fight that can run 30 rounds.

What do techniques and the formation grid add?

A team stands on a 3 by 3 grid, and position is part of the strategy because the six techniques read rows and columns. Every Cromon is born knowing Sweep at rank 1; the Dojo teaches the others in 8 hours, then trains a technique to rank 2 (12 hours, 3,000 Shards) and rank 3 (24 hours, 8,000 Shards). Rarity sets how many distinct techniques a Cromon can know, from 2 for a Common to 5 for a Legendary, never how strong they get: every technique reaches rank 3.

• Guard: Guards the ally directly behind it (same column). Blocks one hit.
• Pierce: Hits the target, then the foe directly behind it (same column).
• Sweep: Hits the target and the foes to its left and right (same row).
• Ambush: Slips past the front guard to strike the back rows.
• Mend: Heals the most wounded ally (itself included), scaled by Resolve.
• Gale Shove: Strikes a foe, then shoves it one row deeper if the cell behind is clear.
• Afflict: Strikes a foe and afflicts it with the caster's element: the foe takes damage at the end of each of the next 3 rounds.
• Haze: Wraps the most endangered ally in a haze: much harder to hit until the end of the next 2 rounds.

So put the Cromon with Guard in front of the fragile striker in the same column, keep a Mend user alive at the back, and expect Ambush to skip your front line entirely.
