If you take 30 Myrmixicuses you got two minion slots left. So let's count Chasme first;<br/><br/>There is 11 CR difference between Chasme and Myrmixicuses. Meaning you get 55 Chasme from using one minion slot (11x5).<br/><br/>Now you got only one minion slot you could split it into half between Yochlols and Dybbuks. There is 13 difference between CR 21 and CR 8 so it is 13x5 and so you can have 65 minions total between Yochlols and Dybbuks. Going by rounded up half 35 Yochlols and 30 Dybbuks example.
