How to defeat beelzebub

[ib]

Most of my characters are around lvl 50-70 but I'm still struggling to defeat beelzebub in the Legendary Ending. Are there any tips to beating him?

I beat him pretty easily - it honestly all depends on how much of the good gear you have. Some of the gear is slightly hidden.
It also speeds up process a bit to get 2x abyssal swords from the IF ending(which takes only ~30 mins to complete and gives 100k exp as well) but it's not necessary, 1 is more than enough.

But even if you lack all that - it's possible assuming you use my buff/debuff strategy, as it was honestly overkill by far.

My character levels were 70-75 and that was honestly unnecessary. that is for all aside of gay louise, who was ~120-130 or something, she levels much faster than others it seems and is most often in the party..

Characters:
Geo Louise - beelzebub takes extra dmg from emblem. With sacred sword she can keep spamming 2x boss judgement into supplication sword for infinite atk/def on belzeebub while dealing heavy damage.

Guinai - like louise, she has the emblem, which deals double.. another good thing about her is salvation light, which gives you immunity to conditions. This won't remove condtions but as long as you upkeep it - beelzebub will essentially waste turns if he does his control skills. So basically spam clean break and salvation on every 5th turn.

Samidare - she is honestly the absolute beast of the game. Her flame octopus is probably one of the strongest skills in the game and scales extremely good. She gets her final weapon if you have the chaos secret character and beat her event in the lava dungeon. With final weapon she deals 6x hits with basic attacks which can potentially deal MUCH more than octopus


Valu - valu has his overpowered kong kim which makes you have infinite dmg/def buff while also being main healer of your party.. he is slightly worse at healing than spiara.. but honestly her skill is overkill and even valu's is more than you need. Once double kong kim is up, just upkeep it while healing up when needed - your damage dealers will deal ~50% damage thanks to that.

Gear:
Louise - sacred sword(got in lava cave dungeon, must have to spam 2x boss judgement > supplication sword rotation which maintains atk/def debuffs on boss permanently), cross shield(strongest matk shield in the game gotten from enchantment barrier clear in chapter 8, which opens way to boss final), alors helmet(got in chapter 7 chest near last checkpoint before the final boss there), dark coat or light coat(both are got in chapter 8 from left prisoner location where you started the game with louise, makes you literally invulnerable)

Guinai - 2x abyssal blade is what I had(the IF battle with guinai in NG+, but you can replace those with any other good matk/atk swords for a bit lesser efficiency), alors helmet(you should have 2nd one, but if you don't - dragon princess hair(got in prologue with samidare in hidden place)), dark coat or light coat(she NEEDS it because her HP is pretty low and 50% reduction is must have), spider silk ball(can't miss it, it gives good stats and a bit TP regen which helps)

Samidare - tenka(best weapon, got from extra fight in lava cave if you have chaos secret character), hair of dragon princess(on samidare it's important since she is not as invulnerable so it helps for her to regen a bit extra), queen's strait jacket or demon armor(both are good), pants(initial equip of the liberator secret character, the best accessory in the game for atk)

Valu - honestly doesn't matter much, just stack def/mdef/matk and have accessory with mana regen... what I had was dalunazia, cross shield, dragon princess hair, edo's armor and cursed amulet. He has a lot of HP and quite good defence so he shouldn't die even if you miss a few things from the list if you have decent def/mdef alternative.

Strategy:
Louise - 2x boss judgement > supplication sword rotation ASAP. Once samidare gets radiance - you can also give her crit spirit buff.
Guinai - cast salvation light ASAP and upkeep it every 5 turns, on other turns just spam clean break.
Samidare - spam flame octopus. If you have tenka weapon - after valu gives you radiance you change into basic attacks.
Valu - get 2x blessing of kim up ASAP, then heal with max mana as needed. Once kim buffs are up and you are safe - put radiance on samidare if she has tenka weapon.

Basically the hardest part is the first few turns until you get 2x atk debuffs, salvation light immunity and 2x def buffs on your party... after that you are literally invulnerable...

To speed up battle further - radiance on samidara with tenka weapon made her deal 5.5-7k non crit and ~17k crits 6 times per attack... average seems to be ~1 crit without crit buff(this means ~50k dmg) and ~3 crits with buff from louise(~70k dmg per turn!!! that's more than bosses occasional heal)

I spread stat giving items like this:
You have 2 inventories - 1 is the 'war/past' inventory and 1 is main inventory.
War/past inventory gets 5x attack from chapter 5 of the game, use them all on guinai, she is the only good character there, since louise stat boosts are not shared with future louise.

Main inventory:
Atk - to samidare
HP - to guinai
MP - doesn't matter, since only support uses it and he probably has regen which is overkill.
Defence - to guinai
MATK - to geo louise
Speed - doesn't matter, I just give it to valu
Luck - guinai or samidare(guinai gets more profit from it early on since it affects her triple/brick attacks - samidare only profits from it after she gets tenka, which you will only use for like... 1 boss in the game)
