Toxi's Enhanced Swords Mod Aims To Improve Swords By Adding The Enhanced Sword,

Currently Swords Are Simple With All 6 Getting Better Until You Reach Netherite, Toxi's Enhanced Swords Changes That.

Casts
Casts Are Obtained By Using Deepslate In A Stonecutter
Casts Are The First Part To Making The Sword, They Are Used To Make Sword Fragments

Fragments
Fragments Only Come In The 3 Required Fragments
Diamond Handle Fragment
Gold Front Blade Fragment
Iron Back Blade Fragment
You Need All Of Them To Get The Sword

Enhanced Sword
Once You Get The Enhanced Sword There Are 6 Upgrades
They Are Obtained By Using The Upgrade Item And The Enhanced Sword In A Smithing Table
Choose Wisely Because You Cannot Remove Them

Upgrades

Nether Star Deals Less Damage But Inflicts Wither
Shulker Shell Deals More Damage And Inflicts Levitation
Heart Of The Sea Gives You Water Breathing And Dolphins Grace When In Main Or Offhand
End Crystal Lets You Teleport With A Ender Pearl But Only To Blocks You Can Reach
Totem Of Undying Gives You Regen And Bad Omen When In Main Or Offhand
Enchanted Golden Apple Gives You Resistance (Added In 1.3.1)

NOTE

The fabric version has new recipes and items, i suggest using a recipe browser mod for the fabric version, but sword abilities are still the same.
