# Info This bright orange fluid is stored in a syringe and charged with arcane magic. You can use an action to administer the shot directly to the heart of yourself or another willing creature. You are protected against [[contamination]] for six hours after receiving a dose of [[aqua expurgo]]. During this time, whenever you fail a saving throw against an effect that would cause you to gain one or more [[contamination]] levels, you can choose to succeed instead. You can use this ability three times, after which the effects of [[aqua expurgo]] expire. If the effects of [[aqua expurgo]] expire in this manner, you immediately take 10 (3d6) necrotic damage and become [[incapacitated]] for 1 minute while you violently retch corrupt bile. Your hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until you finish a long rest. You die if this effect reduces your hit point maximum to 0. The necrotic damage can’t be reduced or prevented by any means.
