Feat: Bless Toxin

You pour void energy into toxins you create to further debilitate your targets. When you Craft an alchemical poison (rather than create it with advanced alchemy, Quick Alchemy, or another means), it becomes a blessed alchemical poison and gains the void trait. When a creature is afflicted with a blessed alchemical poison, for 1 round, any Hit Points it would regain from a vitality effect are reduced by 5, or by 10 if you are legendary in Crafting.
