Multilayer Barrier

Multiple Barriers with one resistance effect each. It's a thin, colorless, invisible coating covering the body. It is a barrier, consisting of several layers but still so thin that Magic Sense can only barely spot it. It doesn't require much magic energy to keep going, either—once it is summoned, it barely consumes any at all.

Acquisition
Rimuru acquired this skill when it turns out, 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 effect each. So Ranged Barrier is now linked with his various resistances to create Multilayer Barrier.
