Landmines and TNT traps and such things of explosive might

[guthriearmstrong]

It's not exactly explosive, but it fits the topic... if I made a trap which had a pressure plate push the victim into the ceiling via a piston, and have a piston open and release lava, would the lava flood be a grief? Not sure on the rules about that.

I could make it explosive too, though

Wait a minute... You can't place water in the nether.
