Join

Joining is a feature where a stack of wandering creatures are willing to become a part of hero's army for free or in exchange for gold. Whether or not the stack will join depends on several factors, but basically if hero's charisma value (C) is lower than creature stack's mood value (M) the creatures will fight. If charsima is greater there are three possible outcomes:

1. the stack will join for free
2. the stack will join for gold, or
3. the stack will fight.

Calculation and factors

Power factor values

k	P
k ≥ 7	11
1 ≤ k < 7	2×(k-1), rounded down
0,5 ≤ k < 1	-1
0,333 ≤ k < 0,5	-2
k < 0,333	-3

Mood values

Aggression	Mood value
Compilant	-4
Friendly	1–7
Aggressive	1–10
Hostile	4–10
Savage	10

M > C → Creature stack will fight M ≤ C → Creature may join

C = P + D + S C is Charisma value P is Power value D is Diplomacy value S is symphaty value H = √(1 + 0,05 × A) × (1 + 0,05 × D) H is hero strenght value
A is attack skill value
D is defense skill value AI is sum of all creatures' AI value A_TOT
