Just to reach lvl 16 Luke, you need to buy some mats from the store (either with real money or crystals). There's absolutely no way in game without the store to reach lvl 16 because you need 50 type 1 base mats per level as from lvl 10 to 14, and even more for lvl 15 and 16. The coliseum only gives 20 of those mats in boxes on 40% and 80% (lvl 1 monsters). So that makes 160 mats total from the coliseum, only to reach lvl 12 Luke. And then it's stuck, no other way to upgrade past lvl 12, unless accessing the store.
