Fabsol's Vodka

Fabsol's Vodka is a craftable Pre-Hardmode potion that is also sold by the Drunk Princess NPC. It grants the Fab debuff when consumed, which gives a +8% boost to all damage but lowers defense by 20 in exchange. While affected by the buff, the player receives 10 extra immunity frames when struck for more than one damage and 5 when struck for one damage. This effect is not boosted by the Cross Necklace or its upgrades but will stack with the extra immunity frames of the Deific Amulet or Rampart of Deities.

If the player is riding the Alicorn mount, the Fab debuff will give a +18% damage boost instead of a +8%.

While the effects of the Fab debuff are mostly beneficial, it is still considered a debuff, and therefore cannot be removed by right-clicking the icon.
