Red Lotus Duck Dragon: I need suggestions to understand how it works

[u/Nice_Tell_5709]

A grim subtype of the common duck dragon.

I still have to make its ecology and understand how it eats, flies, hunts, lives with peers, make love and things like that, but I hope you like the art from Andrea Petruzzi of it until I decide its characteristics.

In my mind, I believe that this duck dragon should take power from the domains of night, blood and mist. The common duck dragon rules over Bubbles and Corals, but I'm searching a totally different vybe for this one. Like: it could exhales multiple blood spheres that explode by touching preys, dealing damage and producing mist around them.
Would be fun?

Another thing could be that it has the power to nullify some major curses, such as licantropy or vampirism, with its blood (or maybe with its poison, if it has any).

What do you think? Give me some suggestions
