The Temple of the Damned unlocks and enhances your Death Knights. Research 'Death Coil', 'Raise Dead', and 'Haste' here. Also, 'Bloodlust' (significantly boosts unit attack and speed) is a must-have. The Dragon Roost offers 'Dragon Fire' for Dragons, increasing their damage output. These magical and aerial upgrades are essential for late-game dominance and can turn the tide of even the most desperate battles. Master their use.
