As for the comparison between Int, Assault and Deceive, the final conclusion reached is that, on average the effect of each stat is: (Matk --> Magic Attack) +1 Int = +1.3 Matk (or +1.25, not sure but doesn't matter too much) +1 attack power = +1 Matk (Assault Lapis) +1 max attack power = +0.5 Matk (Deceive Lapis) For level 3 Lapis, we got: * +7 Int = +9 Matk * +8 Assault = +8 Matk * +8 Deceive = +4 Matk For level 4 Lapis, we got: * +10 Int = +13 Matk * +16 Assault = +16 Matk * +16 Deceive = +8 Matk For level 5 Lapis: Deceive lv3 is worse than lv2 lapis too.
