When you first begin, turn around and run up the stairs and continue on to the second corner. Jump in this second corner to get a red orb cache.
There will be elevator doors from where you begin. Attempting to pass initially will only trigger some Blood Goats to spawn. Afterwards, there will be plenty of enemies inside of the elevator that gives you a great chance to boost up your Stylish Rank. Exiting the elevator, smash everything. At the path beyond the elevator, you will go through 2 doors, and in between a strange room with a single red orb, and keep smashing pots!
After this room and a short hallway, you get a short cutscene showing where to go/ will send out hazardous, flying red orbs at you! Be sure to avoid them, if you wish, because they will teleport you into an area with Savage Golems, and infinitely respawning, saw throwing Mortofinis. These dangerous enemy orbs teleport you to the start of the room, and attack you on both floors you jump to. At the end of the room, there should be a Sacrilege.
On the floor, directly beneath the Sacrilege, you can enter a Secret Room. On the upper level, the balcony, should be a blue orb fragment at the same spot at the room start. Return the way you came, and don’t mind the Pyromancers unless you want to raise your orb rank. If you reach the Divinity statue again, you went the wrong direction. You can still use the elevator again to farm stylish rank, and orbs. Through the right way, (use R2 to keep smashing pots while ignoring the -mancers) you’ll face Bolverk (just use the same strategy as before).
Get the Sacrilege again and get out back into the hallway. You can still get to the Divinity Statue from here. On your way back from the Bolverk fight, you should have noticed a red orb trail. this leads to a room with a few Abyss Goats and Demonochorus. Winning the fight gives another Sacrilege. Don't take the elevator door in the room! Yet. Use it on the lion door right by you, and make your way around the now maze like place you're in. The correct spot from here should be in the same room holding the entrance to the Bolverk fight. Eventually, you should come to a Seal Stone in a room with 4 goat statues. After this fight, Frost Heart is available on the side, waiting for your loving arms. Return to the hall.
Return to the room you obtained the last Sacrilege. It's time to enter another elevator, with more, bigger, enemies. Through the door after leaving the elevator, is a cutscene with a new boss.
Boss: Trismagia[]
To defeat Trismagia, wait for it to split in three, then begin shooting all heads. These heads are each one of a color, and each one has its color and elements:
- The Black, happy face attacks with lightning balls from afar, and thunder rings when it's close.
- The White, sad face attacks with ice balls or/and ice pillars from afar, and an icy cloud at close range.
- The Red, angry face attacks with fireballs from afar, and explosions at close range.
To defeat Trismagia, you must discover which head is the true one, by shooting them from where you stand. Keep switching your targets, until one of the heads feels the pain and loses HP. When the heads get too close, get away quickly, to avoid their attacks. Their final attack is to regroup into one again, and shoot a mega blast from all mouths. Don't be tricked so easily, because this attack does not take the whole area (be careful when its life is low, because from here on, the Mega Blast does, sometimes, take the whole area). So look for a safe spot in the arena to escape. Then repeat the whole strategy to defeat it.
An alternate strategy is to "hit and run" when Trismagia splits into three, and keep doing so until he reunites again into a sole head, as even if he attacks with all the three elements at once in this phase, it should be noted that he also takes more damage while united than when Trismagia is separated. DT-firearms combo will damage Trismagia for considerably more damage.
Afterwards, don't run into the portal immediately. Instead, inspect the chair in the room which will be another secret mission.
