Enhancements are unlocked after fully maxing out an Omni unit's EXP level and BB level. Essentially, they're add-ons that allow the player to further improve their units. These can range from parameter and damage boosts to buffpool expansions. To view enhancements, open your unit's info page and you should see a green button saying "Enhancements" just above the blue "Switch" button.

Do note that enhancements do not come free. Each unit upon unlocking enhancements is given 10 Skill Points (SP), and you can increase their SP by fusing them fodder units you get from quests or by fusing burst frogs/emperors or sphere frogs. SP is capped at 100 and can be boosted to 120 upon Omni +3, meaning you cannot get every SP option available.

I hope this helped! (^^)/
