These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Battle of Olympus
Demonic Snakes: There's several pits of these in Argolis under the temple of Hermes. But unfortunately some of the pits are also bottomless pits.
Goddamned Bats: Bats in the caves of Argolis. Quite a few of the enemies cross into this territory.
Heartwarming Moment: Receiving a Piece of Love results in the player reading through a heartfelt and inspiring love letter from Helene.
That One Boss: The Lamia. Near perfection is required to beat this thing.
