Random Monsters Map Patcher – diverse neutral armies.

2) Add 25% of the strength of the full squad in increments: Melee Fighters (Novice Level), Melee Fighters (Level), Archers, Sorcerers (depending on the difficulty of the game, you can change this).
3) The chance of each subsequent squad appearing is only 50%, with a maximum of 2 full iterations, after which the chance of each subsequent squad appearing is 100%.

I didn't quite understand points 2 and 3.
Please clarify.

Since we have arrays (Melee Fighters (Novice Level), Melee Fighters (Level), Archers, Sorcerers), it is desirable to use them all.
The strength of the initial squad = 100%

We start adding a creature from "Melee Fighters (Novice Level)":

We play a random 50/50:
1) If true, then
We find any random creature that is close in combat spirit (Good/Evil/Neutral), but not more than 25% of the initial squad's strength. If the creature is significantly weaker than these 25%, then we add so many of these creatures to reach these 25%.
We play the next position 50/50, in this case, it is "Melee Fighters (Level)"...

2) If false, then
We play the next position 50/50, in this case, it is "Melee Fighters (Level)"...

The 50/50 is played only in the first and second iterations, that is, after going through "Sorcerers" for the second time, the probability of each subsequent one is always 100%.
