Leveling Hero / Enemy Morph suits and Megabots can normally be achieved by imbuing required consumables to the suit/bot. These consumables are divided into 3 types: Farm Produce, Fish Produce, and Ores. Each type consists of 7 different items giving a total of 21 unique consumables in the game (check Leveling Items and Where to Get Them).
These consumable items are usually found in the treasure chests in the dungeon, sometimes dropped by enemies, or sometimes are plainly rewarded after completing the mission. These items are usually spent on farms, fish pens, and mines in order to obtain the actual produce/items required to level up the suits. There are also higher ranking consumables that are usually required to level up higher ranked morph suits. Higher ranked consumable items are obtained as you progress in the latter chapters of the game or their counterpart patrol missions.
Morph suits and Megabots are level capped for every 5 levels of upgrade. This cap limit can only be unlocked after "Herovolving" the morph suit / megabot with the required consumable items along with the possession of a specific enemy suit (different in every level cap). You may possess enemy suits on the other hand after familiarizing / being friends with specific types of enemies (encountering a specific type a number of times), or simply by drawing them through Lottery Spins.
In addition to strengthening suits through leveling, you may also try modding them (when earning similar suits or upon earning mod points to consume). Lastly, the maximum level of suits and Megabots are 100.
Upgrading Hero Morph Suits
You can upgrade your morph suits using materials such as farm produce (different vegetables) and fish. When your Hero Morph Suits reach their maximum level, you can herovolve them to enable you to upgrade them further.
Herovolving Hero Morph Suits
When a heromorph suit reaches max level, it’s time to herovolve it – using enemies’ suits as materials. Herovolving increases a suit’s maximum level, enabling you to upgrade it further.
Modding Heromorph Suits
When you have enough mod points, you can modify a heromorph suit and unlock new special attacks. Also, you can collect these mod points through battling.
If you win a duplicate suit on the lottery, it will not only increase the parameters of the original suit, but also its mod level. The higher a suit’s mod level and the more mod points you have, the stronger you can make a suit through modding.
