Check your roles before retrying
A boss attempt usually fails faster when every card solves the same job. Cover recovery, protection, damage, and setup before you decide the deck is ready.
Start this Great Floccinaucinihilipilification prep by checking survival, SP room, damage plan, and whether your cards fit the fight before spending more attempts.

The Great Floccinaucinihilipilification (commonly shortened to Great Flocci) is the Demo 4 final boss. The encounter is built around a fake-out: a long-named harmless-looking NPC walks in, then the Fucci demon breaks out and the real fight starts. Treat phase one as a misdirect — the moment the name is fully announced, the kit flips and the first attack is already in the air.
Great Flocci opens with a long word-spell cast (the animation is part of the gag) and then unleashes a screen-wide AOE ink wave that applies Blind and a small damage tick. The cast animation is the only safe window to land burst damage — once the ink lands, the Blind stacks make a clean rotation impossible. Stack one dispel or one shield before the second cast and the fight swings heavily in your favor.
On Hard Mode+, the cast animation shortens, the ink wave repeats twice per cycle, and Great Flocci summons a Fucci-style adds wave between casts. The Blind stacks compound across cycles, so bring a card that removes Blind outright rather than just shielding through the damage. A pure HP build gets wiped in two cycles on Hard Mode+.
A reliable Great Flocci run uses one Blind-dispel card (to clean stacks between cycles), one shield card (to absorb the ink wave tick), and one burst finisher (so the long cast animation is actually punished). Use the build maker to lock in BP, SP, and dispel coverage before entering the Demo 4 throne room.
