College research only costs resources: no gems, no Azurite. So in theory it's free. Run a few more farms and keep it busy.

Research priorities
- Finish every line in Military, and Guardian Force for angels.
- When you have the RSS, finish the other frontline and backline lines too. Elite War needs a 4-1-4 formation, so every troop type matters. See Formations.
- Once the other lines are done, research for more defensive play.
City Defense: what's worth it
- Golems are useless. When you want no troops at home, golems let others attack you and keep you in battle.
- Do go for Alliance Defense I and II: they increase the HP of all your defense troops.
