ReviveDust
The ReviveDust (JP: リザレクトダスト Resurrect Dust) is a consumable found in Chapter 2 of Deltarune. It heals all Downed and Swooned allies to 25% HP during an encounter. Otherwise, it heals 10 HP to all conscious party members or if it is used outside of battle.
It can be found in a chest in Queen's Mansion's acid lake on Floor 3F, at the northwest isle in the house puzzle room. The chest does not appear until the party defeats the Werewire guarding it. It cannot be obtained during the Weird Route, as the area is inaccessible.
In Chapter 4, if any ReviveMint, ReviveDust, or ReviveBrite is in Kris's inventory, Susie describes it as a "peppermint" during Catty's sermon in the church, and consumes one of them in the above order, removing it from the inventory. This causes the AncientSweet to be unobtainable.
- ReviveMints and ReviveDust are uniquely useful in the fight against the Knight, due to the SWOON effect applied when Susie and Ralsei are swooned. The status sets their HP to -999 upon knockout, making all conventional healing items impractical, so it is recommended to stockpile Revive items for this fight, as they bypass this restriction.
- ReviveDust specifically heals downed party members by all of their negative HP plus a quarter of maximum HP, which means that when used with the BlueRibbon the healing is stronger the further negative a party member's HP was.
- Due to this, combined with the SWOON effect, using the ReviveDust with the BlueRibbon can heal two SWOONed party members to near-full HP.
