Squad technology,
without the wrong turns
Follow the named squad lane. Check OR gates before paying for a second branch.
Read the lane label before upgrading
Squads 1 & 4
Terminator I
Monster Slayer I
Squad 2

Monster Slayer I
Squad 3
Terminator I
Monster Slayer I
These are squad lanes, not hero factions
The first lane names Squads 1 & 4. The other lanes name Squad 2 and Squad 3. A hero’s Tribe, Legion or Ranger faction is a separate system.
The shared Grand Harvest gate
Unlock Grand Harvest I
Monster Slayer I (Squads 1 & 4) 3 OR Monster Slayer I (Squad 2) 3 OR Monster Slayer I (Squad 3) 3; Scholar Tower I or II 19
One of the three Monster Slayer I branches at level 3 satisfies the OR group. An eligible Scholar Tower at level 19 is also required.
Then return to the squad lane you need
Survival Drill I requires Grand Harvest I at level 3 and an eligible Scholar Tower at level 20. Assault Drill I then requires that lane’s Survival Drill I at level 1. Shared research is counted once.

Start with the squad you actually use
Compare the benefit of improving your active main formation with splitting research across several formations. The right choice depends on which squads can do useful work now.
Check the fourth-squad unlock
A fourth formation depends on its availability in your client/account. If you use it, the recorded Squad 1 & 4 nodes cover the shared first lane.
