is that true we must raise level to 999 to defeat secret boss ? i see a post in far previous page which tell we need level 999 to defeat secret boss. is it true ? please tell me. cause i want to complete this game not only unlock the scene but also defeat secret boss
(1) i recommend you to at least complete 4 out of 6 main heroine route, and by doing that you will get illumina's called "(girl name)'s love". ex : Akari's Love, Remy's Love, Konoha's Love, etc
that illumina is pretty dope, because it's nullify any status ailments and any debuff.
(2) so at least you must play the game 4 times (1 initial and 3 NG+)
(3) for party formation i recommend : MC, Captain, someone random (i recommend Akari because she can heal), Nana (because she got serious cheat spam skill)
(4) for party's equipment, make sure everyone in front line have 1 love illumina's (recommendation above) and 1 illumina "my power return" that can be crafted from Ikujin
(5) for party's skills :
MC : make sure to get his ADAM "Unity" and upgrade his Attack Power and Critical Rate
Captain : make sure to get her ADAM (skill that can buff party damage power) and upgrade her attack power and crit rate
Akari (personal recommendation) : get her recovery ADAM and upgrade her HP and SP, it would be better if you also unlock her DEF buff skill
Nana : be sure to fully upgrade Nana's SP and get her ADAM the Shield skill (i forgot the skill name, but it can fully recover party's TP), also upgrade her HP if you have time to spare
(6) about party's level i'm not sure how high it need, but al least you need to reach 500 at deff, m deff, and agility for smooth run
(7) also dont forget to farm a lot of angel's drink (item that can do full revive) and a lot of HP recovery (if Nana targeted) and SP recovery because unlike Nana, everyone's SP is below 500 (especially if you reach lv. 130+, Nana's SP is almost 3000)
(8) boss battle first turn : use MC's "Unity", Captain's "party's attack buff", Akari's "party's M Deff buff" (if you already get that, if not then just do some random attack), and Nana's "Spam Skill" (LOL).
for the next turn, just do what you want (i recommend to use everyone attribute/weapon skill, because it use TP and dealt decent damage) but make sure to keep using Nana's ADAM spam skill every turn
Oh yeah, so you know about the secret boss right ? then in those 4 game cycle (1 initial, 3 NG+) make sure to get Offense illumina "Samurai Soul" or in other words keep farming illumina from secret megiddo in every game cycle but you can try subjugate the boss in 4th cycle
