>>314757447Well I'm not sure if you'll be able to max a trap with 20 stars with 40 million stats, but it shouldn't be that hard hard if you have three sages, my current setup is (Killia / Usalia & Three Sages).
I honestly haven't read a lot into maxing your trap since it changed a lot from previous Disgae games where you could just farm the item god, but the kill bonus is higher with max stars resulting in a 2.1 million trap instead of the baseline 500k~ for a maxed trap.
I started farming my first LoC trap with 20 million stats and it started becoming pretty hard at some point so I had to stop and completed my shard farming instead, but even three shitty traps and R41 weapon should give you more than 10 million stats if you have aptitude maxed out and the ATK & INT innocent..
