1. When do these effects occur? After the warlock completes her action? Or after all action phases are complete and just before initiative phase?

2. Is it legal to target your own warlock with adramelech's torment if they have sectarus attached to him/her as it is of the curse subtype? Or target one of your own creatures with a curse like Rise Again on them?

3. Can this friendly creature be then used as a burn generator to transfer the burn onto an enemy's creature with fire weaving?
