Soldier's Syrup (Greater)

ITEM 12
Price 400 gp
Usage held in 1 hand
Bulk L

This thick syrup sweetens potions and creates a distinctive, metallic flavor associated with the festival days in Dhuraxilis. Partygoers are fond of mixing soldier's syrup with potions to extend their release.

Activating a dose of soldier's syrup requires you to combine it with another consumable potion that takes 1 action to activate. After swirling the mixture for a few moments, you must either imbibe the augmented potion within 1 minute, or the potion reverts to its unaugmented state. The potion's level cannot exceed that of the soldier's syrup it is mixed with, otherwise the syrup is wasted.

When consumed, a soldier's syrup–augmented potion does not immediately grant its benefits to you. Instead, you can activate the potion within the next hour as a single action, which has the concentrate trait. You can have only one soldier's syrup–augmented potion consumed at a time; consuming a second one renders the first one inert. If you do not activate the potion within 1 hour, the potion spoils inside you, and you become Enfeebled 1 for 24 hours.
