Coromon is TRAGsoft’s monster-taming RPG. You will travel throughout its world and collect Coromon on your journey. This is primarily done through encountering wild Coromon, but you may be wondering if you can battle other trainers in Coromon.
The answer is yes—there are trainer battles in Coromon. Completing trainer battles is a good way to make money in Coromon, as well as test out your skills on the battlefield. Unlike wild Coromon encounters, trainers can use multiple Coromon in battle. This means you will need to use strategy and the right Coromon for the situation.
There is also an arena on the Lux Solis Campus, the first town you come to in the game. This lets you battle against other trainers and tests out your skills. When facing another trainer in battle, make sure you have your Coromon in the order you want and be ready for a fight.
Use the skills and strategy you learn facing wild Coromon against trainers. Your Coromon will be tested against powerful trainers as you progress, so make sure you train them up right!
