Note: Spoilers up to the end of Act 3
The Aspersorium is a key item which allows the player to remove a fire barrier in Mt. Zugzwang, the final dungeon of the game. This key item is similarly located in Mt Zugzwang and becomes accessible halfway through it. Since this is the final dungeon of the game, it is recommended that the player be fully prepared for this last expedition.
Here are some tips to prepare for the final dungeon:
- Hero at least level 35. The rest of the party should be at least around level 30 or higher. If you aren’t there yet, grinding metal slims is your best option.
- Have the Hero’s Children in the main party. They are some of the strongest characters in the game with great move pools and stats, giving you coverage for nearly any situation.
- Equip the Hero’s daughter with the Sage Stone. This item will allow the Hero’s daughter to become a powerful spellcaster/healer.
- Buy the best equipment you can afford and load up on healing items. This is the final dungeon. Unspent gold is wasted gold.
How to Get the Aspersorium?
Head to Mt. Zugzwang. At this point in the game, the player should already be in the underworld, Nadiria. Once there, Zoom to Precaria. Exit the town and make your way south towards the mountains. Travel west from there and you will find a narrow path around the stone mountains. Once you cross the bridge, simply make your way upward towards Mt. Zugzwang, the final dungeon.
Once you enter Mt. Zugzwang, head straight into the next room. In this room, you will find the floors filled with poisonous areas that damage the party when stepped on. Cast Safe Passage to nullify the damage and Holy Protection to decrease the encounter rate. Once your spells are cast, head straight and climb the stairs towards the next area.
From here, head right at the intersection and take the left path to proceed towards the next flight of stairs.
Head through the singular path until you reach an intersection. Proceed south to climb a flight of stairs. On this floor, head straight up to reach a chest that contains the Dark Robe. Quickly equip this armor on a character as it reduces damage from certain magical spells.
Go back to the previous flight of stairs but instead go up at the intersection. Climb up the flight of stairs at the end of the path. From here, it is another straight path towards the exit. Follow the singular path to the next flight of stairs to head to the next area. Go down and exit outside.
Once outside, travel along the singular path until you reach a small hill that you can climb. Climb the hill and travel left to reach a chest that contains the Ogre Shield. This is another great piece of equipment as it provides a hefty defence boost and cuts breath damage by 10 points.
Head back down the hill and travel left across the bridge. Ahead of you will be a cave. Instead of entering the cave, head upward where you can travel down a flight of stairs. Here you will find a chest containing a Mini Medal. Traverse back to the intersection and enter the cave.
Upon entering the cave, head to the left side and go up at the first exit. At the end of this path will be another set of stairs. Climb the stairs and you will find 2 enemy Dark Shamans at the base of a shrine. Quickly defeat the Shamans and proceed up the shrine to continue the story.
Note: This will start a mini-boss battle with Ladja. Ensure that your party is prepared beforehand.
This fight is pretty easy. There are really no special things to watch out for. Ladja can be easily defeated by debuffing him and continually dealing damage. Remember to heal each turn to be safe from danger.
After the battle, read through the dialogue then proceed down the platform from the left side. You will spot a cave beneath the hill towards the right. Head inside.
This room is a walkway tile puzzle room. This room contains the Aspersorium among other items. Follow the visual guide below to obtain this key item.
Here you will find the Aspersorium. Pick up both items and equip the Sun Crown on the hero. This is a strong piece of equipment for the hero that nullifies enemy kamikaze spells.
What are the Uses of the Aspersorium?
The main use of the Aspersorium is to eliminate a fire barrier in Mt. Zugzwang to proceed with the main quest. However, it does have one secondary use. It can be used to water the Yggdrasil Sapling Knick-Knack to obtain a Yggdrasil Leaf.
To use the Aspersorium to advance the main quest, leave the puzzle room and head down from the cave entrance. You will soon find a path splitting left and right. Heading left will bring you to a chest containing the Double-edged Sword. Heading right will bring you to a cave containing the fire barrier that the Aspersorium can eliminate.
Once inside the cave, you spot a pit of fire in the main area. Walk up to the edge of the pit and use the Aspersorium from your inventory. The pit of fire will disappear, revealing a set of stairs to continue your journey. You are now in the final few moments of the main quest.
