How to kill god item bosses (Cursed swordmaster, Trickster, Drowned knight) 

They are from a plugin

i know i wan't to know what is the comand to spawn them@@MrNightCat

Oh ok, the command is /boss If i'm not wrong.@@caterinabracia1850

then also the boss name. So the command is /boss (boss name) (Location). Idk if you need location

i know but for example if i write /boss cursed_swordmaster 0 0 0 in the chat it says it's wrong, intried to search the command but i can't find it, can you write here the exactly thing you wrote for spawn the bosses? thanks@@MrNightCat
