Batomon Showdown How to Level Up — Merges and Level 4

Batomon Showdown levelling is a merge system, not an experience grind. You raise a creature by combining duplicate copies of it, which means your progress in a run is really a question of how efficiently you turn shop rolls into copies of the units you actually want. The official store page frames this as training your Batomon to overpowered levels, but the mechanics are documented by community guides rather than by the developer, so the specifics below are marked to confirm.

Levels Instead of Experience

The official store description says every Batomon holds infinite potential and that a deep system of unique abilities, trinkets, and items lets you push your team beyond their limits. Community sources supply the structure underneath that claim, describing per-creature levels that raise base statistics, improve ability parameters and unlock trinkets.

Concept	Official wording	Community detail, to confirm
Growth resource	Abilities, trinkets and items	Duplicate copies of the same creature
Level cap described	Not stated	Level 4, called Mythic
Power source	Pushing a team beyond its limits	Stat boosts plus faster cooldowns per level
Shop prices	Not stated	Level 1 creatures cost roughly 5 to 20 gold

Merge Requirements by Level

A third-party guide lays out the merge ladder in copy terms, which is the most useful way to plan a run.

Level tier	Merge requirement	What it unlocks
Level 1	Standard shop purchase	Base stats and the creature active ability
Level 2	Three identical Level 1 monsters	A substantial stat boost and reduced cooldowns
Level 3	Two identical Level 2 monsters, six Level 1 copies total	Maximum ability output and a free Trinket Gift selection
Level 4	Requires a special event or a Mythic consumable	Mythic status, multi-trigger potential and heavy scaling

The practical arithmetic is what matters: reaching Level 3 on one creature costs six copies of it, which is why the same guide advises committing to a carry early and refusing to split your purchases across many creatures.

Level 4 and How Mythic Units Appear

Level 4 is the tier you cannot simply buy. Community sources describe it as Mythic and say it arrives through special events or Mythic consumables rather than through standard shop purchasing, with one guide naming a Monster Professor event and an Ultra Candy item as examples. Official patch notes support the existence of the tier without explaining acquisition.

• Official patch notes reference Level 4 for specific creatures, confirming the tier exists.
• One patch note fixes a creature that gained nothing from reaching Level 4, which shows the tier is a real state with its own effects.
• The exact acquisition path is community-reported and to confirm.

The Day 5 Life Rule

Timing matters as much as copies. A community guide reports that after Day 5, losses deduct three lives instead of one, so a board that is still under construction late in the run bleeds out quickly. The same guide recommends hitting Level 3 on your primary carry by Day 5.

• Aim to have your main carry at Level 3 before the stricter loss rule kicks in.
• Do not spread merges across three or four creatures; concentrate copies on one or two.
• Use trinkets and items from levels and events to cover the gap rather than buying extra bodies.

What Is Still Unconfirmed

Several specifics remain undocumented by first-party sources, including exact statistics per level, the full list of Mythic acquisition events, and whether the Day 5 life rule is universal across modes. Official patch data is the most reliable place to watch for changes, since balance patches have already adjusted specific creature numbers more than once.
