This mod is currently in 1.12.2 and may get updated in 1.16.5 too!
It adds some legendary weapons and items as an addon mod to Ice and Fire!

Hand of Hydra!
Fight the hydra and use her deadly fangs to craft a mighty sword!

Hippocampus Slasher!
Use the colourful fins and make a sword that gives buffs when it rains!

Pixie Sword
Annoy your enemies and make them glow!

Desert  / Jungle Myrmex Swords!
Use the skin from the myrmex to make a poisonous legendary sword!

Sapphire Rapier
Who said gems are not op?

Wither Bane....
Well, why not!

Stymphalian Heavy Blade..
Well those pesky birds hurt but their feathers seem quite useful!

Troll Hammer
Bash your enemies with those tusks!

Troll Pickaxe
Use the powerful tusks of a troll and mine a 3x3!

Chitin Swords!
Who said fighting worms is fun?

Contained Essence:
Crafting an empty jar with a fire / ice dragon heart will capture the creature's essence!
Use it to gain asbroption 3 and strength 2 for a limited time or have it in your inventory to gain passively resistance and strength!

Fiery Eye
A simple fire resistance giving artifact!

Flesh to chicken like?
Yeah flesh other than straight consuming it doesn't have any other use so +1 for you!
Craft 1x flesh and one bone to get a meat on bone!

This mod turned out okay (I was hoping I could do better but I have a lot to learn)

Currently there's one bug.
The recipes for the chitin swords (and their repair materials)  won't work (or you can add the musing crafttweaker)
If you use a contained essence item and have another in your inventory it will consume both (So please have only one when you want to use it)!

Update:
I plan to add more weapons or items related to this amazing mod Ice and FIre (which you should check out)!
