Rimuru Tempest gains Shizu's, Ifrit's, and the Orc Lord's powers by swallowing and killing them. Can he gain their abilities without killing them? Could he swallow someone without killing them, analyze their abilities and spit them back out alive? Could he analyze their abilities by touch instead? Thanks for your time!
In order to mimic a monster Rimuru would need to use predator to swallow a monsters body. But Rimuru can also swallow someone just to analyze them like in the case of Veldora he swallowed him so that Great Sage can analyze the barrier around Veldora in order to break it. But Rimuru has never copied a skill just by touching.
