Multilayer Barrier

Multilayer Barrier (多重結界) is an Extra Skill upgraded from Ranged Barrier. Rimuru acquired this skill when he couldn't create a single barrier with lots of different effects applied to it, but he was free to create multiple barriers with one Resistance each. It became an Intrinsic Skill of Demon Slime after Rimuru's evolution.
