Blackspell Rice

Blackspell Rice (魔黒米) is a species of magical plant that resulted from Rimuru's experiments using grass plants grown in Magicule-rich water in the Sealed Cave.

Appearance
Blackspell Rice looks like regular rice that an octopus squirted ink all over.

Effects
Blackspell Rice contains a large amount of nutrients and Magicules, making it toxic to beings with a low tolerance to Magicules, especially to Humans.

However, someone with a Resistance to Magicules can convert Blackspell Rice into energy. It can make for a good medicine, because its energy is usually converted into Magic Power.

Trivia

 * It is one of Tempest's local product and a staple food for its citizens.
 * The beneficial effects of Blackspell Rice on Humans with high tolerance to Magicules were discovered in Territorial Seizure when Fritz first tried it, much to Rimuru's horror.
