PREPARATION
You can stock up marching speed up (if possible) as timing is very crucial in Tri-Alliance Clash
BASIC STRATEGY
The only way for an alliance to win the match of Tri-Alliance Clash is by gathering point from holding a building
One person are in control of 3 squads
Remember you use energy for
Moving
Healing
Reviving
Manage your energy accordingly
R5, R4 and the assigned legion commander (maximum of 2 per legion) can appoint their teammates to become captain of the captured building that will help them in regenerating energy.
This is an important task to ensure teammates with low energy become captain of a building
If you are strong and pretty confident of your power you can use gem to speed up queue of battle when it reached more than 5 match waiting on the list
You need to manage role within your teammates into :
Attacker and defender
Floater (preferably the weaker teammates) : someone who specialized in running away, avoid direct battle with the enemy squad and only focus on taking an enemy building which happened to be empty at that time
Only R5, R4, and the appointed commander that can manage building captain during battle
Legion commander will be someone rank lower than R4 (R3 and so on)
Remember being captain of building = more energy recovery
That's why. Managing captain of the building is also an important job, because you will want to distribute energy evenly across your teammate to prevent unnecessary waiting time
