One of the my complaints about summoning spells is the rigidity of the summon monster and summon nature’s ally lists. I understand the argument that if you open it up to all the monsters the spells become far too versatile. So I’m proposing a solution where we selectively open up the lists via an imprint sphere.
Aura faint divination; CL 5th
Slot none; Price 250 gp; Weight – lbs.
This fragile sphere is colored red and black (for arcane casters) and green and brown (for divine casters). The wielder throws the imprint sphere at its intended target with a ranged touch attack. If the sphere hits, it breaks and knowledge of how to summon that creature is imparted to the wielder if it meets the proper requirements.
Arcane casters can only imprint animals, magical beasts and outsiders.
Divine casters can only imprint animals, magical beasts, outsiders [elemental] and plants.
The wielder can only imprint creatures that have the same challenge rating or lower than creatures that they can already summon with the summon monster or summon nature’s ally suite of spells. Once imprinted, the creature is permanently added to your list.
Requirements Craft Wondrous Item, creature loresight*; Cost 125 gp.
