Soulforge Depths

Past the eight-sphere gate the Soulforge Depths change the flavour of the puzzles: instead of garden altars you're opening the way with items from your inventory, wall buttons and torches. Walk every room in full before you move on – the keys that let you continue sit in separate mechanisms.

The first set of alcoves carries inscriptions pointing at ordinary items by where they come from or what they do. Born of mountains takes a Rock, Sweetest prize of the orchard an Apple, Never to carry, only to break a Pickaxe, and Made to carry the earth a Shovel. Put each one in its matching alcove.

Check the apparently empty room along its walls. There are four wall buttons in it, not one; press all four and the way to the first iron key opens. The second iron key sits in a chest by another mechanism: pull the lever to open the gate, then throw an item onto the plate inside. That unlocks the chest beside it.

Further in you meet a numeric inscription and torch pillars laid out like a clock face. Light the torches in the positions matching the hands at 2:35. Which pillars exactly, and how the hour hand is drawn, we cannot confirm, so compare the inscription with the pillars in front of you. Solve it and a key to the next stretch appears on the altar.

The Test of Dexterity is optional and not needed to progress. Throw a stone onto the far plate at the end of the corridor. A gate opens on the other side; go through for the key and use it on the chest nearby.

From the Depths the route drops down into The Furnace. Heal up and restock before you take it – what waits below isn't something you can simply back away from.
