War bases at TH16 need to prioritize anti-3-star design above everything else. In Clan Wars, defenders only need to prevent the perfect attack — even a high-percentage 2-star is a successful defense. This TH16 War Base Anti Hydra (Merged Defenses) uses compartmentalized defense placement to force attackers into difficult pathing decisions.

Key defensive buildings like Inferno Towers, Eagle Artillery, and Scattershots should never be reachable by a single Hero dive or Siege Machine path. This layout separates high-value defenses across multiple compartments, requiring attackers to commit spells in different areas rather than stacking them for maximum value.

Trap placement is critical in war bases. Spring Traps should cover Hog Rider and Root Rider pathing corridors, while Seeking Air Mines need to protect against LavaLoon entry angles. Giant Bombs paired with small bombs create kill zones that eliminate support troops like Wizards and Bowlers before they reach the core.

When using this war base, consider adjusting trap positions after each war day. Experienced clans scout and plan attacks based on trap predictions, so rotating trap locations between wars keeps your base unpredictable. The compartment structure of this layout gives you multiple viable trap positions without weakening the overall design.
