How does the buff system work?
Lets say I got 4 ninjas of the same elemental, but my main buffs up to 3 of them.
How do I predict or choose who will get that buff?

So far, both relative position to main and placement order seems to affect who the buff lands on, but I haven't figured out how exactly it works yet.
* Once you get the correct ninjas buffed, you can move them as you want without losing the buff.


Sample 1:
Placement order: Main -> Kabuto -> GNW Tenten -> Tsunade

Kabuto, GNW Tenten, Tsunade
X, X, X
Water Main, X, X


Result: Water Main, Kabuto and GNW tenten gets buffed



Sample 2:
Placement order: Main -> Tsunade -> GNW Tenten -> Kabuto

Kabuto, GNW Tenten, Tsunade
X, X, X
Water Main, X, X


Result: Water Main, Tsunade and GNW tenten gets buffed




Sample 3:
Placement order: Main -> Kabuto -> GNW Tenten -> Tsunade

X, X, X
X, Kabuto, X
Water Main, GNW Tenten, Tsunade

Result: Water Main, Kabuto and GNW tenten gets buffed



Sample 4:
Placement order: Main -> Kabuto -> GNW Tenten -> Tsunade


X,X,Kabuto
X,X,GNW Tenten
Water Main, X, Tsunade

Result: Water Main, Tsunade and GNW tenten gets buffed
