  A modifier is always stirred in before the herbs, and it shapes the brew as a whole:
<~><~>  Honey makes a sweeter, gentler tea that lingers longer.
<~>  Sugar quickens the brew, though it fades sooner.
<~>  Glowstone Dust empowers it, deepening the effect.
<~>  Redstone makes the effect linger far longer.
<~>  Milk soothes the brew, keeping it calm and safe.
<~>  Blaze Powder overcharges it with raw, restless power.
<~>  Amethyst Dust refines it, coaxing out a hidden second effect.
<~>  Fermented Spider Eye corrupts it into something darker and unpredictable.
