The monsters that look like a crystal give a ton of Sp but you can only deal 1-2 dmg max to them and they often run away they also have 10 or so hp at most. No moster that give a lot of exp only dragons.
Tricskter, Psychic, Idol eh? Well, learn Rush Shot if you use Gun Type one while your Psychic use any low cost MP that hits All the Enemy, I don't really knows what Idol do so good luck using it for buff or something lol
On this team comp you would have to use guns normal attack its 2 hits instead of 1 then follow up with idols assault groove and hope it wont run in 1st turn. Psychic is unfortunately uselles for those.
In the first game, the Flower Roshid (the crystal like monster) give 300exp and 100sp. His others form after give a lot more (Flower Roshid DX: 1000exp 300sp) . But in this game, I killed one but it didn't gave me the same... So does it still give the same amount of Exp and SP in 2020-II or now it just give sp and not much exp?
