OK, I've seen plenty of tutorials to build them, but they all go upward like a pyramid, is there any tricks to make it flat on the ground and integrate it into the floor, can I put any kind of blocks over it to make it flat or the altar needs to see the runes all around, getting ready to start my altar room on top of a tower and I planned 5 blocks down before the ceiling of the lower level so I have plenty of space for it, should I make it 6 for the Tier 6, I'm not 100% sure here. Basically, I don't like the pyramid shape of it and want to avoid using carpenter wedge slopes since they cause a little bit of fps lag.
