The Mortal Kombat Weapons mod (MK Weapons for short) adds weapons from the Mortal Kombat universe and series of games. Each weapon has a special effect, though some do not. Each sword will require a special material, called sanctified iron, which is crafted with an iron ingot and any enchanted book.
Sento (replace iron with sanctified iron in all recipes):
Kenshi's enchanted katana, it contains the souls of his ancestors, which blinded him while first retrieving the sword. Was used to kill Song, who revealed himself earlier to be the villainous sorceror Shang Tsung. Comes with Knockback 3 on craft.
Kori Blade (replace ice with packed ice):
Sub-Zero's bone-chilling ice blade. Packs an iron punch and puts slowness 3 on the target for 30 seconds.
Scorpion's hellish sword, it was said to have "Made in Hell" stamped on the blade. Comes with Fire Aspect 2 upon crafting.
