In this level, you might attract new creatures like Warlocks (require a Library) or Horned Reapers (require a Temple and sacrifice). Warlocks are excellent ranged attackers, while Horned Reapers are devastating melee units. Prioritize building a Library (3x3 minimum) to research new spells and attract Warlocks. Researching the 'Heal' spell is highly recommended for keeping your creatures alive in prolonged engagements. Also, consider building a Temple (3x3 minimum) if you want to try attracting Horned Reapers, but be aware of the sacrifice mechanic. Experiment with different creature combinations to find what works best for your playstyle.
