Merge Elementals: Castle Defense

Instruções

🖐 Drag identical elementals onto each other: two fighters of the same type and tier fuse into the next tier. Gold only buys tier one — everything above comes from merging, and grid space is tight, so think about what you combine. ▶️ Once your line-up is ready, hit Start Wave. Merging locks during combat: your fighters aim and shoot on their own, while your job is to cast spells on time and keep the wall standing. 💰 Every kill drops gold. 🔁 Wave over — back to the prep phase: buy, rearrange, upgrade. The last wave of each world is a boss, and beyond it lies the next biome. 💎 If the wall does go down, you can revive on the spot for gems and carry on.
