Whatās up currently my build got 4 extra points and I have been thinking what to use them on

What do you guys think of:
- Stone curse https://www.youtube.com/watch?v=pOS3RwShwZw
- Prominence (not sure how effective the smaller range one is)
- Rain (for slow)
like, would the Stone curse work on players? (probably) would it work on bosses? does Prominence have a lot of damage at the long run, would itās randomness be effective on mobs or in pvp? is it worth it to level the Rain for AOE 10% movement speed? Or should I just increase the Electrocute to decrease itās casting time
Thanks in Advance
