I still think the cult is underpowered the revamp did make them stronger, however, the black rose is still stronger in every way the only thing cult has over the black rose is that each member can become the cult leader
I had a few ideas to change the cult up and will explain my reasoning
1, * Unlimited Uses, but 1-day cooldown. I suggest you remove the day 1 cooldown. the cult leader has both the job of killing and converting and if the cult starts with 2 members, the leader and another. at night 2 they will have 3 members but will 1 will die making their total 2.
if they could also convert night 2 they will have 4 members and convert is like killing only you get help. they will die later of course and it may be pointless
removing the day 1 cooldown would change the cults play style making it more different than the black rose. it will also help them deal with the losses from killing their own members and other killers like the paladin. without this, they are a glass cannon that shatters easily
2, make it that when the cult leader kills a cult member to kill someone he can choose anyone even himself. this will let the cult kill off members who are suspicious. of course, the cult can’t bypass immune so they may just waste a life for nothing
sometimes killing your newest member when he is your best hope will not always work out
