I think it going on the head is funny but right clicking on the laser blade causes it to swap with my helmet,

PS i know it is WIP but i think a nether star or a beacon requiring recipe will be good

That was an unexpected behavior, but it was funny and harmless, so I'll keep it as is.

also eating with offhand with laser blade causes it to block with sword

also can you keep the unicorn saber but make it togglable because placing down torches and eating makes helmet swap....

Thanks for the report.
I'm going to fix it so that the laser blade in offhand behaves well while player is using an item in the main hand.

It will be fixed in next version.

Unfortunately, I couldn't reproduce the problem in my Forge 1.18 environment, so I'm thinking to fix it so that laser blades can't be worn as helmet.

I have released v1.18-5.1.1.1. Please try it out.
