In Clash of Clans clan wars, a well designed war base protects your storages and makes it harder for enemies to three star you. Focus on balancing defense versus offense, so your traps and defenses work together while allowing your clan mates to rally behind a common plan. Tailor layouts to your town hall level and typical enemy armies, not just a pretty map.
Key layout principles include placing the town hall at a defensible core, building multiple compartments to slow troops, and using traps to punish common attack patterns. Mix air and ground defense coverage so both air and ground armies meet stiff resistance. Avoid predictable funneling and ensure traps aren’t triggered too early by scouts.
Adapting to an opponent means reading their army composition and choosing defensive targets accordingly. If enemy air decks are common, strengthen air defenses around the core and deploy air seeking bombs. For ground assaults, reinforce with a smart combination of single and splash damage and time your multi infernos to force suboptimal paths. Use replays to refine the design after each war.
Practical tips include saving base templates, testing layouts in practice with friends, and updating bases after patch notes. Keep symmetry where possible, but bias toward layers that draw single target troops away from the town hall. Record your results, rotate base designs seasonally, and rely on your clan's feedback to improve protection and star potential.
