No, Condensed resin can only be used in domains. Trounce Domains and normal bosses do not take condensed resin. However, Fragile resin can be converted into Original resin and used if the player has run out of Original resin. Although, it is advised to save the Fragile resin for much more needed occasions due to its rarity. (1 Fragile resin= 60 Original resin)
