Chapter 17 of 24 · Finish the story
Prepare the two ending keys
Complete the Zagreus memory sequence below the House, obtain Gigaros, and stop the storm around Typhon.
Do these first
Full steps belowTwo route requirements open the ending
Both routes can be cleared with one reliable aspect and the full Surface is open.
The final story sequence requires one completed chain from each route. More clears alone do not open the ending until both named chains are complete.
Know what each route contributes
- Underworld clears lead through Zagreus's bedchamber and a sequence of memories.
- Zagreus eventually leaves Gigaros for the incantation that can stop Typhon's storm.
- Disintegration of Monstrosity costs one Gigaros, one Zodiac Sand, and four Void Lenses.
Collect both ending requirements
- Repeat the Underworld route for Zagreus
Clear Chronos, enter Zagreus's bedchamber, and complete the available conversation or interaction before leaving. Use zero Fear for the lowest-risk story attempt unless another explicit objective requires Fear. Return on later clears until Zagreus says he will leave Hades's spear for you.
- Take Gigaros from the bedchamber
On the next relevant visit, collect the spear when it appears. Do not spend it elsewhere. It is the unique ingredient for the Typhon incantation.
- Reveal Disintegration of Monstrosity
Meet one of these conditions: discuss how to weaken Typhon with Hecate, or Use Returning to a Real Possibility at the Fountain of the Dead at least once. Gigaros is part of the brewing cost, not the reveal condition. When the recipe appears, reserve one Zodiac Sand from Chronos and four Void Lenses from Typhon attempts.
- Brew the incantation before fighting Typhon again
Spend one Gigaros, one Zodiac Sand, and four Void Lenses on Disintegration of Monstrosity. The recipe turns Typhon's own power against him once he is weakened.
- Clear the Surface and stop the storm
Use the proven setup, defeat Typhon, and finish the incantation-driven storm sequence. This produces Entropy and completes the Surface half of the ending gate.
If one route objective does not advance
If the recipe has not appeared, do not grind Typhon. Continue Zagreus's bedchamber sequence after Chronos and speak with Hecate after every return. If the recipe is ready but materials are missing, farm only the named boss drops and use zero Fear when no separate objective requires it.
