I need ideas for my modjam mod

So, I'm participating in the Curseforge x Mcreator Modjam. I'm making a Vanilla+ / Magic mod. Here's the list of feature I have.

Link to all of the Features: https://docs.google.com/presentation/d/1Q-pqm314i5b7F9G9o3Xh0r6SzZF2pcnycseNYdHulZo/

-Ancient Pot (Block)

A loot pot that generates in the deep dark biome. It drops useful resources like echo shards and rarely diamonds.

-Wizard Tower (Structure)

A new structure that generates in the overworld. It has a lapis brick roof, and inside is a library with chiseled bookshelves full of enchanting books and also a written book that describes the first steps of getting started in the magic system.

-Lapis Bricks (Block set)

Bricks that are crafted with lapis lazuli and cobblestone

-Bone Sword (Weapon)

A weapon made of iron and bones that has mid attack and durability, but very fast speed.

-Diamond Dust (Item)

An item that is crafted with Amethyst Shards, Echo Shards, and a Diamond. It is used to craft spell books and other magical items.

-Magical Upgrade (Smithing Template)

A smithing template used to craft spell books and other magical items.

-Diamond Spell Book (Weapon)

Shoots fast projectiles at enemies. It does have a cooldown. so you can't do rapid fire.

-Caveling (Mob)

A new hostile entity that appears as a deepslate block with long limbs and a giant green eye.

-Illusioner (Mob)

Using the MC dungeons texture, it functions the same as the base game, now with a spawn egg and is in survival gameplay.

-END CONTENT-

-Platinum (Tools, Armor)

Platinum ore can be mined in the outer end islands. It can be forged into platinum tools, which are more powerful than Netherite. There is a smithing template required for this.

-Topaz (Ore)

Topaz can also be mined in the outer end islands. It can be crafted into a Topaz Staff, which shoots fast moving fireballs with no cooldown. It also has a building set that is similar to copper.

-Eyeling (Mob)

An end version of the Caveling that has more health and attack. It drops platinum ore when killed, so it is worth it to hunt them if you don't like mining. Only spawns in the outer end Islands.

I need some ideas for Magic Weapons and structures. Currently, the Smithing Templates are unobtainable, as I don't have a good way for them to be obtained yet. Any ideas?
