[MULTIPLE ENTRIES] List of Obsidian and other "Hard Materials" in SkyBlock

[GreenMiner33]

I took a while trying to consider what to include for this vague, general category. Usually, I have what each one means planned out beforehand. For this poll... that was not that case. I eventually settled on Obsidian, Iron Bars, Cobblestone Walls, Stone, Heavy Weighted Pressure Plate, and Stone Slabs.
(Reminder: purple represents items with the enchantment glint by default.)

Obsidian​

• Obsidian: Formed when water touches a Lava source block. Can be purchased from Builder for 99 coins, or found in The End/Deep Caverns. This item cannot have an enchantment glint.
• Enchanted Obsidian: A compressed form of Obsidian. Crafted with 160 Obsidian. Can also be obtained from End Nodes.

Iron Bars​

• Iron Fence: 16 are crafted with 6 Iron Ingots. This item cannot have an enchantment glint.

Cobblestone Wall​

• Cobblestone Wall: 6 are crafted with 6 Cobblestone. Can also be purchased from the Builder for 2 coins each. This item cannot have an enchantment glint.

Mossy Cobblestone Wall​

• Mossy Cobblestone Wall: 6 are crafted with 6 Mossy Cobblestone. Can also be purchased from the Builder for 2 coins each. FUN FACT: This item doesn't exist in the API! An item easily obtainable in 1.8 survival worlds, AND on Hypixel... is not in the official items API. It also is completely unsellable to NPCs. This item cannot have an enchantment glint.
  (...fun prank: give someone asking for "free stuff at map" 16 stacks of Mossy Cobblestone Walls)

Stone​

• Stone: The smelted form of Cobblestone, or Silk Touch form of itself. Can be purchased for 2 coins each at Builder. This item cannot have an enchantment glint.
• Polished Granite: 4 are crafted with 4 Granite. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.
• Polished Andesite: 4 are crafted with 4 Andesite. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.
• Polished Diorite: 4 are crafted with 4 Granite. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.
• Hard Stone: A block mined up from Crystal Hollows (and, in the future, Glacite Caves). Requires Breaking Power 4 or higher to break. This item cannot have an enchantment glint.
• Andesite: An igneous decoration block. 2 are crafted with Diorite and Cobblestone. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.
• Grante: Crafted with Diorite and Nether Quartz. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.
• Enchanted Hard Stone: A compressed form of Hard Stone. Crafted with 576 Hard Stone. Can still be compressed further.
• Diorite: 2 are crafted with 2 Cobblestone and 2 Nether Quartz. Can be purchased for 3 coins each at Builder. This item cannot have an enchantment glint.

Heavy Weighted Pressure Plate​

• Parkour Checkpoint: An iron chestplate used for making Parkours. Costs 1,000 coins from Amelia. Requires Social 1 to use or purchase. This item cannot have an enchantment glint.
• Heavy Weighted Pressure Plate: A simple pressure plate which costs 12 coins from Mad Redstone Engineer, or can be crafted with 2 Iron Ingots. In terms of Redstone, every 10 entities on it past the 1st adds +1 to the output. This item cannot have an enchantment glint.
• Trap: A trap for enemies in Dungeons. It does decent damage to all enemies close to it when stepped on, which scales slightly with floors. Can be obtained from Dungeon secrets. This item cannot have an enchantment glint.

Unused/unobtainable Heavy Weighted Pressure Plates:

• Festive Frisbee: The API specifies it "doesn't do anything... yet!"

Stone Slabs​

• Quartz Slab: 6 are crafted with 3 blocks, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Stone Brick Slab: 6 are crafted with 3 Stone Bricks, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Brick Slab: 6 are crafted with 3 Brick blocks, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Nether Brick Slab: 6 are crafted with 3 Nether Brick blocks, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Stone Slab: 6 are crafted with 3 Stone, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Cobblestone Slab: 6 are crafted with 3 Cobblestone, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.
• Sandstone Slab: 6 are crafted with 3 Sandstone, or can be purchased from Builder for 2 coins each. This item cannot have an enchantment glint.

Stone Slab 2​

• Red Sandstone Slab: 6 are crafted with 3 Red Sandstone, or can be purchased from Builder for 2 coins each. Apparently, this item ALSO does not exist in the API. Why do unobtainable items like Large Fern and (for SkyBlock) Dragon Egg exist in the API but cheap, obtainable vanilla items AREN'T? This item cannot have an enchantment glint.

---

In terms of inventory space:

• All 25 items obtainable can manage to fit in one's inventory, even without anything in the hotbar.
  • There are more of these items normally-obtainable total than there are these items in the API.
• The total cost is ~7.8k coins (roughly 7,816.9 coins), roughly 3.9k of which is from Enchanted Obsidian.
  • Both obsidian items cost a total of roughly 3,953.6 coins.
  • The cost of only one Iron Bars item is roughly 1 coin.
  • Cobblestone Wall and Mossy Cobblestone Wall in total cost 4 coins.
  • All 9 Stone items cost a total of roughly 2830.3 coins.
  • All 3 Heavy Weighted Pressure Plates cost a total of roughly 1,012 coins.
  • All 7 Stone Slab variants (plus "Stone Slab 2") add up to 16 coins.

Almost forgot the poll, now it just says "POLL WIP" as the question.
Which start/end letter types do you want to see an item list for?
