A random table could be nice? Even the stat bonuses could be rolled :P Then there could be some other benefits depending on the consumer's condition. Exhausted might get their vigor back, wounded get some temporary hp boost, unconscious get healed back up, could regain spell slots etc. Maybe you would then have to use will or con to resist some side effects that could have to do with being deliberately aroused, suddenly desiring the Gabriel (even more than usual) and sexual themed debuffs like that?
