The Aevitas Mantle currently likes to break light sources created by the illumination wand, makes lenses pop off relays, breaks items that are in lightwells, and traps players underneath them...
I suggest we make it not a real block technically or something... Some way where it wont effect the world other than when a player stands on it, as these things only get increasingly annoying...

Cyclic implements this nicely- they have a curio that negates gravity and doesn't affect the world with invisible blocks.

Have a look into the code for inspiration, @HellFirePvP, if you must.
