It really depends. Lvl 60 is now exponentially harder after the winter kings. With 1 knight I can reach lvl 18 or 19. By the time I reach lvl 43 I am using all 5 (unless double weakness can be exploited). To reach lvl 60 now using only epics owned ny friends typically takes 20 gems (10 at the start to accelerate and 10 at the end to kill lvl 60). The best way to know when you need to add a new knight is when the boss reduces the health of the second knight in your line up below 50%. I have friends in centurions so my friend list is very strong and I have a good selection of armors.

For void sentinel I had 2 max horseman+ and Krampus+, along with several friends who have blazestone. Given this I reached lvl 60 a day early. I will likely fail with the current boss though, since I only have 1 strong spirit armor not weak to this boss, but I will try.
