Just so that the player isn't draining all their resources just to get at least 90 Gold Ingots (which is 90 Gold Ore for the regular player, or 45 for the lazy Ore-Doubling player, or 23 for the fat-ass Ore-Quadrupler who exploits mods just so they don't have to play Minecraft), the blocks for the frame will be replaced with Keystone Blocks.

These blocks are made with 4 Crystallized Redstone, 4 Crystallized Lapis, and 1 Gold Ingot. This emphasises on the whole "dimension is made of precious earth minerals" and gives a bit more purpose to those items for those who got a Miner's Tree and realised how much Redstone there is underground, and for how mostly useless Lapis Lazuli is.
