What is the best/ quickest way to level up your monsters?
South of Deucalis, by the shore, there can be around 10-30 biteschools that offer 3000-9000 XP very easily. They’re very easy to KO. Use AoE attacks to best 3 at once by the way.
I find a team with haste, a monster with a short tu chain skill works very well. This way your able to do the entire fights and never take any damage as they will always be to slow to attack you before they die. Also a great place to train your first ones as lots of damage is done in short order.
