As discussed in #131 (comment)

Xalcon suggested wither

1. Change how the megatorch works, ignoring the height and only checking x and z coordinates.
2. Add a different block that has a bigger range but only checks for phantoms.

I'd be up for submitting a PR that implements either of these options. If you have a preference, Xalcon, let me know and I can do whichever you like. I can't add the texture for any new blocks though. You'd be on your own for that, but I could make the code and a debug texture file in the mean time.

Phantoms are properly blocked now, so no need for this
