The first actual dungeon with two separate paths really, as Misty Lake doesn't differentiate between Normal and Hard paths at all really. The Hard path is a lot more difficult than the Normal path by far, as it has the Parasite enemies, and the player can run into upwards to six of them in one fight. The bosses are also different until the last fight on both paths, where the final fight will always be the same, sans different boss music.


Monsters encountered:

Kedama: Standard all-around resistant enemies, and your typical Self-Destruct user.
Forest Specter: Weak enemy in terms of defenses and HP, but hits pretty hard with Shadow-elemental and Lightning-elemental attacks.
Ameboid: Mushrooms that can inflict various statuses, including Poison and Sleep, to the entire party. Highly dangerous and should be disposed of first.
Toxic Plant: Fought mostly on the Hard Path. Specializes in Poison-elemental attacks, making them quite dangerous as Poison is one of the three Advanced Elements.
Heal Rabbit: More of a nuisance than anything else, as they tend to heal HP/MP/Statuses and revives others. They tend to come in groups.
Parasite: The Notorious Monster of the area. Loves to use Gravity spells as well as inflict the Lock status effect. Tends to come in groups of threes or sixes with itself.

Bosses encountered:

Rumia: Fought three times on the Normal Path, and only once on the Hard Path in the final fight. Is fought alone once on the Normal Path, then with enemies the second time, and finally with Mystia on the Normal Path. Specializes in Shadow-elemental attacks and can single-target heal. Not too big of a threat and is more of a nuisance compared to Mystia. Rumia absorbs Shadow, but since nobody in the party uses this, it matters not. Weak to Holy, meaning Reimu is extremely effective against her.
Mystia Lorelei: Fought only once in the final fight on the Normal Path. Fought once in the final fight in the Hard Path, and with enemies once on the Hard Path. Is much more dangerous than Rumia, and is the first actual boss to introduce a variety of status effect attacks on the entire party. Mystia is meant to have the player come prepared with status-healing items (particularly, Antidotes for Poison, Eye Drops for Blind, Echo Notes for Silence, and Alarm Clocks for Sleep), or else she can easily cripple the party. Aya is largely useless unless she has Graceful Dash, as Mystia absorbs Wind.
