btw, did some research, endercrystals only blow stuff up horizontal or above it, it doesn't destroy anything under it so it wont create a large crater. You can use it to "guard" your entrance or at least the position of a guard would stand when guarding a house(cuz imo it looks good that way). give it some distance so it wont blow ur house up. Other wise its a very good decoration piece that if used correctly can be quite safe.
e.g.:::::::::::::::rip
:::::::::::::rip rip rip
:::::::rip rip rip rip rip
rip rip rip end-cry rip rip
safe_safe_safe_safe_safe
as you can see, the end crystal doesn't destroy blocks under it.(the rip stands for is destroyed and the safe is not destroyed, destruction radius not to scale or dimentions of blocks) the : is for filling in space cuz the crafty program auto moves it to the left even with space
and honestly idk how big of a deal (half a heart) or dying is to you guys, I have 350 deaths so I don't really care.
