Start with path control, not wall HP
Moats and steep terrain are valuable because they change how enemies can approach your structures. Treat them as path-control tools rather than a promise of invulnerability. Leave one deliberate route you can observe, repair and defend instead of creating ten accidental entrances.
Raised earth is a perimeter, not the whole defense
A thick raised-earth ring can make ground approaches awkward, but it does not solve enemies that fly, jump, spawn inside an unsecured area, or attack from unexpected elevation. Keep critical crafting and storage one layer deeper than the outer perimeter.
Build one real gatehouse
Make the entrance a useful checkpoint: clear line of sight, room to fight without clipping into doors, repair access, lighting, a nearby chest with food/arrows/repair materials, and a second interior door or fallback line. A gate should be easier for you to use than for an event wave to exploit.
Give ranged defense a job
High walkways and towers are most useful when they cover the gate, shoreline and likely event approaches. Do not place ranged positions only for symmetry. If a position cannot see a threat before that threat reaches important structures, it is decoration rather than defense.
Protect the recovery path
Your strongest base can still fail you if you die outside and every spare set is buried in random chests. Keep a labeled recovery station near the exit with backup food, rested-comfort access, portal materials where relevant, basic armor and a weapon you can afford to lose.
Use this as a plan, not a guarantee
Valheim is actively patched. Test tactics in your current world and adjust for world modifiers, group size and your own gear. The goal here is to reduce avoidable losses and wasted building, not to promise a perfect strategy.
