[Stealing from Others]
Accessing the Body of an enemy breaking the Spiritual and Astral bodies of target like Razen does, or using skill-theft specific skills like Gluttony, Usurper or Mammon, allows one to acquire the target's skills.

Rimuru: So that's why he (Razen) said that only the outside was japanese but the inside was a wizard

Gazel: It is very impressive that you could take care of him, he was the one responsible for Falmuth's Glory

Rimuru 'Well it was Diablo who did it, But I myself almost kill him accidentally, So I guess for a human level he was strong'

Velzard: Wait a minute now... It was possible to share skill with others ?
