This recently came up in a game I was in where a party was stripped of all their posessions and jailed. Could an artificer still use a curative admixture healing power? The flavor seems to suggest it is an object the artificer creates, but the desrciption is very vague. I know it's ultimately up to the group to decide, and in my game the DM allowed me to use it, but I'm just curious to hear others' interpretations of this class power.
Actually, the Eberron Player's Guide answers it for you in the flavor text. I'm paraphrasing, but in the class description, just before listing the infusions, it says something like,
"Artificers use magical ingredients in their infusions, and if they don't have the correct materials on hand, they transmute common materials into what's needed."
So, That artificer who's shackled in a dungeon cell, I envision it more like:
--He takes some of his own blood and spittle, uses his Arcana to make an invocation that transmutes this into one component;
--takes some dead insect carcasses from the old lice-ridden bedding and the corner of his cell, transmutes that with a few magical passes into a second component;
--finally, mixes these together, which makes a vaguely insectoid magical construct which breaks his shackles and rips the door off its hinges, and fights the guard in the hall before dissipating.
Later, he can take some transmuted metal shavings and powdered flint, and start infusing the rocks he throws with deadly force.
