There’s a thread over on Paizo.com’s boards titled Stuff You Wish Paizo Had Done During Pathfinder 1e. This thread is awesome for ideas for material to create for Pathfinder 1e.
I just want to take a moment to thank every person that contributed to that thread; your thoughts are invaluable. Today we’re presenting an idea coming straight from that thread. The item is based in the elemental gems, except it summons an ooze. More ooze vials will be coming as soon as I have a chance to make more.
Black Pudding Vial
Aura moderate conjuration; CL 11th
Slot none; Price 3,300 gp; Weight —
A clear glass vial contains a viscous black fluid and held inside by a black cork and sealed up with wax. Should the cork be removed or the vial be broken (such as by throwing it), a black pudding appears. It is mindless but attacks the closest creature, even if the creature was the one that removed the cork. The black pudding has the extraplanar subtype. If the black pudding has not been destroyed after 11 rounds, it disappears, returning to it’s home plane.
Requirements Craft Wondrous Item, conjure black pudding; Cost 1,650 gp
