|Effect:||Unattended, nonmagical object of nonliving matter up to 20 cu. ft.|
This seed creates a nonmagical, unattended object of nonliving matter of up to 20 cubic feet in volume. The caster must succeed at an appropriate skill check to make a complex item. The seed can create matter ranging in hardness and rarity from vegetable matter all the way up to mithral and even adamantine. Simple objects have a natural duration of 24 hours. For each additional cubic foot of matter created, increase the Spellcraft DC by +2. Attempting to use any created object as a material component or a resource during epic spell development causes the spell to fail and the object to disappear.
The Conjure seed can be used in conjunction with the life and fortify seeds for an epic spell that creates an entirely new creature, if made permanent. To give a creature spell-like abilities, apply other epic seeds to the epic spell that replicate the desired ability. To give the creature a supernatural or extraordinary ability rather than a spell-like ability, double the cost of the relevant seed. Remember that two doublings equals a tripling, and so forth. To give a creature Hit Dice, use the fortify seed. Each 5 hit points granted to the creature gives it an additional 1 HD. Once successfully created, the new creature will breed true.
