I need HELP! I'm HURT! I can't feel my BEARD!
Jokes aside, I don't understand the execution dungeon's boss mechanics.
What does Struggle do? How does tanking work? Why is anyone with the 1hp poison still instakilled? How do I manipulate my formation? By never reviving anyone that is physically in place before lily? How do I beat the boss that has 3hp?
2 die (guards)
Atk Guard Atk Guard
2 dmg dealt
2 die again
Game over
So here is what you should know
1. You must have full party members, that means all 8 playable characters (not counting Mebius of course) before attempting this bad end dungeon
2. Only Polca and Lily can deal damage, all the struggle commands are meaningless. Other party members are nothing but meatshields
3. Trying this dungeon will only give you some CGs, lores and minor rewards in NG+
4. Your party will die a lot, stock up revive potions as much as you can from the dungeon, if one die, try to revive them immediately
5. The dungeon can be considered a rouge lite puzzle game, you got farther through gaining knowledge, not stat or skill
6. The Guard enemies can't harm you and can be killed in 1 hit, the Circle and Butterfly enemies are the same, but it will always take a party member down with it, so other than Polca and Lily, other member must always guard to take hits for them
7. You do not need to fight everything just what necessary to proceed, level is meaningless here so bypass all that you do not need to fight.
8. Do all humiliating things in front of the red crystal to get useful items, they are must get
9. There are many shortcuts and secrets, you will not be able to figure all of them in 1 try, but the second, the 3rd,...n+1 times, you definitely will, hence I say this dungeon is like a rouge lite game. Pay attention to everything, hit every wall to see if you can walk through them.
10. Some enemies like the grim reaper takes more than 2 hits to kill. You can either sacrifice some party member to get them through normal kicks of Polca and Lily or sacrifice at least 1 party member and kill them with some special items
11. Some floors have challenges that seem not worth trying at first but will help you much later. Also, there is a floor that will trick you that it has no challenge, it is a trap, you must find the challenge of that floor, otherwise, you can't get much deeper more than 2 floor ahead
