Yeah, from what I've tested though the buildings won't fall apart until you break or place something near it, which I kind of like because it means there's a risk to living inside what's essentially a free house.
Thank you so much! Xiroc did I fantastic job bringing my ideas into reality, and I hope people seeking a greater, but fair challenge will enjoy it!
@xiroc1337 Alright, so it seems that the Ender Dragon fireball explosion doesn't seem to deal damage to the upper body of the player. In addition, I've decided to make some other changes for the sake of balancing:
-Ender Dragon's max HP is now 250.
-Wither's max HP is now 350.
-Blazes will now drop 0-2 Blaze Rods instead of 0-1.
