Feat
Twofold Elixir
Binds two spells into one permanent potion
The character can bind two spell effects into a single gold-stabilized potion. A Twofold Elixir can be created only through permanent crafting: it requires gold and a long ritual under the ordinary enchantment rules. It cannot be prepared as a temporary alchemical mixture or sustained as a mana-bound enchantment.
Both effects must be valid potion formulas and use the same method of delivery. Drinking or applying the elixir releases them simultaneously on the same creature or area. Each retains its own spell level, caster level, Spell DC, damage, duration, and defenses.
The ritual requires the full ingredients and crafting cost of both potions. The GM sets the gold cost from their combined power and considers the complexity of the pairing when prescribing the crafting time and chance of success. An incoherent combination may be refused before resources are spent. For example, a Nausea solution designed to shatter when thrown cannot be combined with a Heal potion designed to be swallowed.
Gold stabilization makes the potion last indefinitely until used; it does not make it reusable. Consuming the Twofold Elixir remains one general action and destroys the potion.
