Lightning Rod

Any lightning rod in a module slot.

What it does

It shields against three quarters of the interference.

Interference comes from:

lit portals (nether portal, end portal, end gateway, not their frames) within about 6 blocks,
the nearest enderman within 8 blocks (an angry one disturbs twice as much).

The closer the source, the more snow and buzzing in the picture.

The Netherite CRT needs no lightning rod; nothing gets through to it.
