The Unquenchable Thirst is a bronze trophy in The Blood of Dawnwalker, and it is one of the game’s 17 hidden trophies. Its unlock condition is short and blunt — find out the truth about Vicho — but the wording hides the fact that the investigation runs across two different times of day. Miss the daytime half and the trophy never fires, even if you already know who the culprit is.
Quick answer: Run the night investigation, question the other Valkyrie until you identify the vampire who cannot control their thirst, finish the night questline, then return during the day and complete the merchant’s quest that formally names the culprit. The trophy pops on that final reveal.
The Unquenchable Thirst trophy details
The trophy sits in the bronze tier alongside most of the game’s quest-specific unlocks. It is worth 10 Gamerscore on Xbox and counts toward Every Last Drop, the platinum. Because it is hidden, the description stays masked in your trophy list until you trigger it.

Why the trophy does not pop
Two things account for almost every failed attempt. The first is stopping after the night questline, assuming that naming the vampire is enough — the daytime merchant quest is the actual trigger. The second is time-of-day mismatch, where players look for the merchant after dark and conclude the quest is bugged.
A third, rarer problem is self-inflicted. Killing non-hostile NPCs, vendors, or quest givers can remove the person you need, and there is no substitute path. Enemies are fair game; townsfolk and merchants are not.
Tip: Keep a manual save before you begin the night investigation. Manual saves are the safety net for the whole trophy list in this game, and they let you rewind if a conversation or objective closes off in a way you did not intend.
Time cost and the 30-day limit
Time in The Blood of Dawnwalker does not tick along on its own. It is spent like a currency on dialogue choices, skill unlocks, and quest completion, which means this investigation costs you part of the 30 days you have to rescue your family from Brencis.
That budget is more forgiving than it sounds. The main story can be wrapped in roughly 7 to 10 days, leaving around 20 days for side content. Side quests also do not expire from time simply passing — they only become timed once you start them, and the journal marks those with an hourglass icon. The game continues past day 30 and side content remains available, so a late run at this trophy is fine.
The Unquenchable Thirst is one of 47 trophies and achievements in the game, split across 1 platinum, 3 gold, 5 silver, and the remaining bronze. It asks for no combat skill, no build, and no difficulty setting — only that you follow the investigation through both halves of the day-night cycle before you tick it off the list.
