Feat: Bless Tonic

You channel vitality energy into restoratives that ward against harm. When you Craft an alchemical item that restores Hit Points (rather than create it with advanced alchemy, Quick Alchemy, or another means), it becomes a blessed alchemical item and gains the vitality trait. For example, an Elixir Of Life would become a blessed elixir of life. When a creature regains Hit Points using a blessed alchemical item, the overflowing energy grants them void resistance 5 for 1 round, or void resistance 10 if you are legendary in Crafting.
