Cliff

Cliff is a natural, indestructible terrain block that appears as raised, impassable rock on the battlefield. It forms elevated ledges and barriers that units and most building placements cannot traverse or occupy. Cliffs shape chokepoints, line-of-sight, and pathing on maps and therefore play a major role in tactical map design and defensive positioning.

Cliffs cannot be mined, built upon, or replaced by normal construction; they act like permanent walls in the environment. Units that normally ignore terrain (such as flying units) can pass over cliffs, while ground units must path around them or use map-specific features (ramps, stairs, or teleportation) where the map author provides traversable links. Projectiles may interact with cliffs depending on line-of-fire rules: cliffs block direct line of sight for ground turrets and many weapons, making elevated flanks and turret placement sensitive to cliff geometry.

• Use cliffs to funnel enemy ground units into narrow approaches where area defenses and chokepoint turrets are most effective.
• Place long-range artillery or anti-air on open ground with cliff cover to protect flanks and create safe firing corridors; cliffs can block enemy turrets from returning fire if line of sight is interrupted.
• Remember flying units and naval units ignore cliffs for movement; cliffs offer no protection versus aerial assaults unless combined with anti-air defenses.
• Map-specific mechanics (ramps, cliff breaks, or custom tiles) can allow selective traversal; always inspect map features for planned unit routes.
• Cliffs are permanent map geometry and unaffected by status effects or building abilities; they do not apply or carry status effects themselves but influence when units traverse tiles that do (for example, forcing detours through hazardous tiles).
