Thonda'a's Crucible is a spell of cruel entrapment. The caster holds the material component, a ceramic crucible, and casts the spell. Upon completion of the verbal and somatic components the caster may make a melee touch attack against any creature. On a successful attack the creature becomes entrapped in the crucible via a dimensional warp and the crucible is filled with molten metal. If the caster fails a concentration check, before a successful touch attack, the spell ends with no effect. The trapped creature takes 3d8 damage per round, DEX save halves. Two successful saves in three rounds allow the creature to escape the crucible and end the spell. Dispel Magic during the three rounds ends the spell immediately.
Any creature in the crucible for four rounds becomes encased in solid metal. The creature is affected as per suffocation rules. The only means of escape is the destruction of the crucible or a wish spell. The crucible has 500 hit points and is resistant to cold. Fire does double damage, but half of that damage is passed on to the entrapped individual. Destruction of the crucible disrupts the dimensional warp and releases the creature.
Thonda'a was a vile, abusive wizard who attempted to craft this spell to cast upon a fellow mage who did not return his affection. His intended target uncovered the plot and finished the spell in secret. Thonda'a became the first victim of the spell that bears his name.
