Hello!
I hope this is not arrogant of me, but I decided to draw for you the idea of a new boss, and also came up with features for him.
I hope my experience will seem successful for you and you will like my idea) I hope I will be useful for you!)
So:
Leviathan
According to legends, Leviathan in most stories is a huge monster, amazing in size ...
But I don’t know who you would like to represent as the main and most powerful opponent, so I suggest you choose the size (if you like the idea).
Habitats and behavior: Usually lives at great depths, but goes hunting to the surface. He loves rocky areas and sunny weather (snakes like to bask in the sun). He has a sharp ear, so he goes where there is a lot of noise. He is rather persistent in pursuing prey.
Varieties of attacks, weaknesses and behavior in battle:
On the sketch I indicated the weaknesses of his body color: this is the mouth, nose, neck, back of the body and the tip of the tail (where the stripes)
Hit them will cause critical damage.
Places such as plates on the neck, top of the head, at the paws (and the paws themselves) are pretty well protected and the damage will be reduced.
During his appearance in front of the player, he defiantly emerges and grinds his teeth, pushing out his jaw (I pulled out the whole jaw, and not just teeth like snakes) In battle, usually stands near the side of the ship, (like the tentacle of a kraken), and tries to knock the player off decks. When it receives critical damage, hisses very loudly. Before attacking the ship (with a jerk with its mouth open, it bared 2 large fangs), gets up in a characteristic pose (like a snake) and looks exactly where it is going to strike. When it hits the ship, it always leaves 2 large penetrations and periodically 2 more small ones.
When standing at the side of the ship it usually attacks with a stream of boiling water (since this is a water snake, I decided that there would be boiling water, not poison)
Boiling water causes periodic damage and passes over time.
Able to capture ships as kraken:
He does this with his paws, trying to crush the ship under water, and at the moment of such a capture, he always keeps his head at the bow of the ship.
To loosen his grip, you will need to beat him in the nose, eyes or mouth so that Leviathan will let go.
You can force him to let go with swords or firearms
about the color of the skin, it's your choice)
I would also suggest adding 3 varieties of leviathan
ordinary (spits with boiling water) lava (lives with volcanoes and spits with lava) and deep (spits with mucus, which does not damage, but slows down for a while)
Of these three, the deepest would be the rarest and most timid; for the most part, he would avoid fights.
and that’s all)
I hope you were interested to read and see my idea)
I also hope that it will be useful to you)
Thanks for your attention)
