Summon a slime to fight Preta

You search the Demon Summoning Program to find something that can use to fight this demon. You don't really think about what you you try to summon. You'll take anything at this point. What you summon is a green slime demon.

Slime Origin: Unknown. The remains of a demon that failed to form. They need Magnetite to materialize in the human world. This is what becomes of them when they don't get enough to fully manifest.

Stephen mentioned nothing about magnetite. Well you're gonna need to get him to fight.

The Preta gets closer.

"Go, Slime, attack." you say.

The Preta tries to charge in a hit, landing a big swing on the Slime before retreating.

The Slime is barely fazed. You check the DSP for more information on your Slime.

The Slime is nearly immune to blunt force. Eats fluids. Can absorb living and non living materials.

As well as you can tell Preta has no skills other than blunt force. The Preta runs away.
