Io nel frattempo ho cominciato a buttar giù l'incantesimo epico che dovrebbe essere necessario per creare questo oggetto... Provate a vedere cosa viene fuori... diciamo che uno spellcraft di 100 non è proprio per tutte le tasche, a prescindere dal fatto del solo costo materiale.

You can summon a primal elemental from the plane of fire or water or earth or air (see Epic Level Handbook for details). It appears where you designate and acts immediately, on your turn. It attacks your opponents to the best of its ability. If you can communicate with the creature, you can direct it not to attack, to attack particular enemies, or to perform other actions.
A summoned monster cannot summon or otherwise conjure another creature, nor can it use any teleportation or planar travel abilities. Creatures cannot be summoned into an environment that cannot support them.
