Atlus recently revealed more on how demons can level up and grow in Shin Megami Tensei IV. Your befriended demons in Shin Megami Tensei IV will become stronger by winning fights and leveling up.
By leveling up, the demons will increase in attack, health and various other stats. They will also learn new skills, which will be crucial in fights as demons with more skills will have more chances of hitting enemy weaknesses.
Additionally, there are some demons that will evolve into completely different demons when they level. This feature is known as the ‘High Level Up’.
Demons can also teach you new skills through a feature known as the “Whisper Event”. These events will occur over time after leveling up your demon buddies. Learning several different demon abilities will play a big part in helping you become more powerful.
Shin Megami Tensei IV is slated to be released on May 23rd for Nintendo 3DS.
