what about a viking that is a melee that uses its axe and it has a hat but it is lost and once u defeet him he will ask if u could find his hat and he will give u a map that will lead u to clues to find it and when u do find it and give it to him he will give u something and he is made out of bones with moss on the bones

I have heard you suggestion and I will try to add at a later date

Thank you all advice is very kindly accepted

I would Love to but i can only do 1 type of attack ranged or melee

Fallen angel would be cool!
So basically a fallen angel is a miniboss(?) That attacks you with lightning strikes and a flaming sword! They can also fly, and their projectile attacks leave a debuff called Icarus' Judgment, which disables your elytra and makes it so you take 150% damage from their attacks.

They would be found in the Nether, and would drop fallen feathers, which can be used to craft some mid/end-game gear, like the Aegis of Sin, a shield that protects you from about 100% more damage than a regular shield! The downside? It has a chance to inflict a random debuff on you, about 1-25% when you use its charge ability, which deals 25-200 damage.

If you see this, please consider! I just put this together in like 5 minutes!
To be honest, it sounded a lot cooler in my head...
