Ok.... Then maybe all the airpockets in the ground will show up as the void blocks that you can see through anything instead of changing all the earth into barrier blocks.
Ummm. It (Tremorsense) is not a hack if it's meant to be in the plugin - This is what tremorsense is, seeing the earth around you like no one else. There are lots of ideas and ways Tremorsense can be done though, but we are obviously limited.
Its a bending plugin, yes but we yet don't have a combustion dealing 10 full hearts, because BALANCE (it makes sense cuz P'li died without getting an injury, so should that be implanted?). This should be nerfed to some extent, because ppl will be able to find secret dungeon easily and as ArchBear_Vega said - finding other people bases who work hard in hiding. Look at Spiritual Projection opness debate and you'll see most dislike the idea of "am guna pres a buton n now I fond everything, lol k bye".
