Runic Equipment

I've played Minecraft for a long time and my favorite things are those that are difficult to obtain and rewarding.

Runic equipment would be much more difficult to obtain than any other item in the game, which would make it legendary. Runic shards could be located in  loot chests. These shards could be combined 3x3 in a crafting table to make a Runic Shard. Runic Shards could then be combined 3x3 to make a Runic Relic, which could be applied to diamond armor and tools like netherite ingots. Runic equipment would have the same durability as diamond and not be fire proof, a slightly higher enchantability, and the armor would have the same protection. It would also be noticeably more efficient for tools, do about 2 hearts more base damage for weapons, and it would have unique bonuses. 

Runic Boots would give the player jump boost while equipped.

Runic Leggings would increase player speed.

Runic Chestplate Would increase fire rate of weapons / efficiency of tools.

Runic Helmet would give visibility improvements (increase in brightness, decrease in fog, maybe a slight brightness increase on ore blocks and hostile mobs).

All Runic Tools would would have slightly more range than other tools, allowing the player to have 1.5 blocks increased reach, and I picture the equipment looking very bright and angelic (White and gold).

I have lots more ideas about this, and I'm open to suggestions. Feel free to ask any related questions below!
