TH12 Trophy Base: Core Lock

A defense-led trophy layout that buys time, protects the Town Hall, and stretches attacking armies.

01 · Defensive idea

What this layout is trying to do

Layer the Town Hall with splash damage and point defenses while preserving enough space to disrupt spell value.

Trophy protection can expose collectors and make routine farming less efficient. That tradeoff is intentional: a useful base has a clear job instead of trying to win every possible exchange.

Best reasons to try it

  • It centralizes the main objective.
  • It forces longer travel.
  • It supports overlapping defensive fire.

02 · Placement guide

Build it as a system, not a picture

Start at the center and work outward. Place the main objective, then the defenses that protect it, then the walls that force an attacker to spend time reaching them. Exterior buildings come last because their spacing determines how easily an army can create a funnel.

  1. 1
    Lock the core

    Layer the Town Hall with splash damage and point defenses while preserving enough space to disrupt spell value.

  2. 2
    Split premium defenses

    Do not let one freeze, jump, or hero route solve every high-value target at once.

  3. 3
    Shape the approach

    Offset outside buildings and wall openings so the easiest funnel does not point directly at the core.

  4. 4
    Set traps after the structure

    Set seeking air mines just beyond the first defensive ring, where healers and heavy air troops tend to commit.

03 · TH12 context

What mattered at this Town Hall in 2020

The weaponized Town Hall turns the main objective into a defensive structure, so safe access to it should carry a real cost.

The pressure this layout must answer

Siege Machines can manufacture a route to the Town Hall, while Electro Dragons punish aligned buildings and short chain gaps.

Placement note

Break long building chains, offset the Town Hall from the Eagle and Infernos, and leave enough internal space that one spell cannot cover the complete core.

Replay checkpoint

Check whether the siege path reaches the Town Hall without meaningful detours. Shift approach buildings before moving the Town Hall itself.

04 · Layout-specific field note

Force the siege to reveal the rest of the plan

The Town Hall should be reachable only through a route that exposes where the remaining army must travel, without aligning every defense behind it.

Adjustment to test

Offset Eagle and Infernos from the objective lane, then use gaps that make post-Town-Hall pathing less direct.

Evidence to collect

Follow surviving troops after the Town Hall falls. A clean continuation into the Eagle signals too much alignment.

05 · Replay lab

Three checks before you keep it

Entry

Which edge do attackers choose, and which outside buildings make that choice easy?

Spell value

Can one spell affect the Town Hall and more than one premium defense?

Pathing

Where does the main army change direction, split, or leave a defense standing?

Review three comparable defenses before making a large change. Move one or two traps first; change the structure only when the same route keeps succeeding.
