Where it fails

  • Air Sweeper gapServiceable
    sweepers face inward; the 10 o'clock line is only partly coveredAttacker will: send a Blimp or air group along that line
  • Central Spell TowersServiceable
    clustered in the core; one Freeze covers bothAttacker will: Freeze both when the push arrives
  • Core trap laneServiceable
    traps sit on one path; a second path avoids themAttacker will: enter from 2 o'clock
  • Long RC pathServiceable
    6 o'clock path is long but openAttacker will: clear outer buildings first

Patches since publication

How the base works

  1. 1The attacker sees spread compartments and a deep Town Hall.
  2. 2Expected path: a funnel from 2 or 4 o'clock toward the core.
  3. 3Defensive value is spent on wall rings and the long back end.
  4. 4It can fail against Root Rider smash from 4 o'clock: the path stays open and short to the core.
Deny 3 stars: spends value on wide compartments and the long back end; gives up some Town Hall safety.
