Good idea,but there are something call wall and they should be best material for walling...
I nerf the recipe to make it 4 brick instead of 3 (wall cost 5)
and buff the health to 275 (wall has 350)
so wall has 70HP/brick
while brick chest has 68.75 HP/brick
and it is updated,so you can check it out,if you got anying tweaking request I will be happy to discuss here :>
