Doedre's skin Mechanics

I was wondering, for example, if I have 4 curse limit, and have already 4 curse on that enemy, will curses on Doedre's effigy override those curses, or rather add more curses on top of the first 4?

Usually curses from different sources can't stack. So I imagine only your curses *or* the Effigy's curses would apply.

Just tested, it does stacks with other curses, Malediciton gave me a higher damage bonus with Doedre's effigy out

Edit: Apparently is seems to be a bug, effigy overwrite curses, phearps when an enemy it's killed, becuse of the curse on hit, all curses are unable to expire before monster death.

So, just a piece of junk.
