Aside from above basic skill effect, players can also evolve the core skill at the Home Laboratory, where you’d be needing some Chips and Research Result item for you to upgrade these skills.

Boosting Core Heroes

When you’re at Level 1 to 50, Core Heroes will only have those basic effect we listed above. But when you reach further more level and activated the Laboratory, this is the time you can evolve the Core skill of your Core Heroes.

For this guide, we will use Genos as an example, so everyone can relate since this is the most common Core heroes in the game. Once you’ve unlock Laboratory, you can now upgrade their core skills, which adds additional stats for every level you upgrade. It will also unlock alternative new core skill that has different Advanced effect as well as improve basic core skill at the 4th unlock.

Core skill can be upgraded when all core parts are upgraded to the same level. For example, when all core parts reaches level 1, you can then upgrade the core skill to level 1.

The material use to level up the parts can be obtained from the following quest:

  • Home Request
  • Research Materials
  • Core Trial
  • Mall (Tournament Coins, Contribution)

Once the Core heroes evolves, it will unlock new perks for your core hero and unlocks new core skills. The maximum level perks for Research Evolution is at Lv. 20.

Here is the list of example perks for Genos Core skill upgrades.

It will not only provide additional boost during the battle, but also gives you a bonus Battle Points (BP) when you activated and upgraded all of other Core Heroes character in the Laboratory.

Initially, there is one slot for Core Heroes that will give you a Total Bonus when you’ve upgraded the Core heroes. The Total Bonus is automatically added to the overall lineup.

Additional BP Bonus slot can then be activated when your account reaches Lv. 55, Lv.65, Lv. 75, Lv. 85 and Lv. 95, the more you fill the available slot with core heroes the more you’ll get bonus BP.

Best SSR monsters for Every Lineup

For the best SSR monsters for every lineup in ONE PUNCH MAN The Strongest is the Subterranean King, this monster is not just an effective AOE Row Burner but effective match for every lineup that you think of.

The secret lies to its combination of Passive and active skill, the Lightblade Slash and the Underground King. It’s AOE Lightblade Slash will give a damage and burn effect to main target and a 50% chance to grant burn effect to other targets in the front row. If those enemies with burned effect attack to your lineup, Subterranean King will immediately do a follow up attack against the enemies without losing any turns.

It is very effective to any lineup because this monsters is independent and already have its own burn effect that utilize its passive follow-up attack. But ofcourse, putting a Core Heroes that at-least 2 Energy points for every round will give advantage to your lineup.

Slash LightbladeAttacks a single target with 2 consecutive strikes for 130% ATK (+1000) damage.
Subterranean Rage

Cost: 2 Energy
Attacks each enemy in a row with 5 consecutive strikes that deals 140% ATK (+1022) damage, with a 100% chance to afflic the main target with Burn for 2 rounds (60% ATK as DoT), and a 50% chance to afflict targets in the same row with Burn effect for 2 rounds (60% ATK as DoT).
Underground KingAfter an enemy in the Burned state has taken action, Subterranean King immediately launches a Follow-up attack with 80% basic ATK DMG and effect, up to 3 times each round.

Permanently increases HP by (???)

To make Subterranean King more effective, you also need to raise its ATK stat for more damage. You can do that by putting up gears that contains stats for ATK. For example, a blue gear item that has 1,000+ ATK.

Aside from gears, you can also get more ATK damage from the Exclusive Item the Keepsake Light Blade Subterranean. We have no data for the default ATK value for here, but when it reaches level 47 and unlock 1-star, you’ll get ATK + 1022 and ATK + 12%.

You can also activate the additional perks by collecting specific heroes and monsters. For subterranean King, you need to collect Alpha (Tank-Top Master, Puri-puri Prisoner, Deep Sea King and Sky King), and Subterranean Clan (Subterranean, Subterranean Brute and Subterranean Champion). The total attack damage you can get in the perks is 20% + ATK.

Limit Break, next goal is to level up its Limit Break, each upgrade in limit break will give specific additional ATK, like for example in upgrading to 4-star, you’ll get a total of ATK + 300.

Lastly, the Journey Goal. If you’ve scrolldown to character Journey there is a specific objectives that you need to achieve in order to get additional stat. For Subterranean King, you’ll get an additional +600 ATK by unlocking objective which is unlocking the Limit Break for (Subterranean King, Deep Sea King, Groribas, Carnage Kabuto to 3 stars).

Other than increasing characters stats, there are many more ways on increasing the lineup stats, we will not go through to each but you can get more from the following:

  • Figurine (Home)
  • Training (Home)
  • Memory (Saitama)
  • Talent (Saitama)

Strategic Lineup Formation

Aside from increasing lineup Battle Points (BP), there is a strategic ways on winning the battle even though you have fewer Battle Points than your enemy. This is by picking up the best hero for the line up and making a formation which will give you the best defense system for your heroes and monsters. Formation are very important for auto battle and for arena in which your lineup will automatically battle without your control.

Don’t forget to add a Core Hero to your lineup to give extra Energy Points, then Subterranean King for damage and burn effect. Then lastly, other 4 characters of your choice that will assist your lineup and give more fire power.

In Front Row, always put the characters with highest defense or health. This is important so that you be able to protect your important characters from taking a damage.

In the Back Row, place the most important characters with the highest damage or buff. The purpose is to make less damage to your last line of defense and they will be the remaining characters who will fight at the end of the battle.

That’s pretty everything for this guide. If you haven’t downloaded yet the ONE PUNCH MAN The Strongest, you can get it from Google Play and App Store. You may also visit their official Facebook Fan page and website:
