A progression hub for Lelia, Hanya, the three combat actions, ability unlocks and the route toward the cathedral. Check your current abilities, keys and conversations to identify a next step.
Scope: the Steam release of 15 May 2026. This is a documentary guide comparing the official store, official achievement definitions and dated player records. It does not certify the installed current build, every enemy weakness, fixed drops or every branch. Features from another edition or an external patch are not assumed to behave identically in standard Steam play.
Before setting out
Show or hide section
Lelia performs the exorcism work; Hanya supports her with research and treatment. The official spellings are Lelia and Hanya; a player guide's Haanja spelling is treated as a variant.
Before entering a new area, check controls, difficulty, recovery and movement options. The official description includes remapping and difficulty settings; do not assume a fixed binding across configurations.
| Action | Practice focus | Check |
|---|---|---|
| Normal attacks | Learn the basic close-range action and whether you can leave safely after attacking. | Avoid repeated attacks without watching the enemy. |
| Ranged magic | Use arrow magic while checking line of fire, walls, enemy alignment and remaining magic. | Distinguish the piercing and exploding upgrades from the initial arrow. |
| Melee magic | Compare close-range magic with normal attacks and use it in an opening. | Test its range, cost and startup with your controls. |
Magic abilities
