Joiner First-Slot Rule
Only the first hero slot contributes to joiner skill effects.
Key mechanics
- Only the first expedition skill of that first-slot hero can be added.
- A rally uses up to four extra joiner skills total.
- Second and third hero slots mostly matter for carrying more troops.
- Joiner gear, research, and buffs do not define rally stats; rally leader stats do.
Stacking tip
Mixing compatible heroes with different effect identifiers can produce stronger multiplicative gains than repeating the same hero four times.
