TH15 brings Root Riders — burrowing troops that ignore walls and surface directly at defenses. A TH15 farming base needs Giant Bomb corridors on underground approach paths to DE and Drills, plus multi-mode Inferno coverage for the Super Witch Skeleton swarms that pair with Root Rider armies.
Town Hall 15 introduces Root Riders — the first troop that ignores walls entirely by burrowing underground. This changes farming defense fundamentally. All the wall layers and compartments that kept Goblin Knife and Super Goblin armies out of your DE core don't stop a Root Rider. For the first time, resource protection at high Town Hall levels requires trap-based defense rather than wall-based defense.
Root Riders burrow underground and surface directly beside defenses, bypassing walls completely. In farming attacks, they're paired with support troops — typically Super Witches generating Skeleton swarms, or Super Goblins dropped into the breach the Root Rider creates. The Root Rider takes out a defense from underground, then surfaces to tank while Goblins or Skeletons clear the surrounding resource buildings.
Standard farming attacks using Root Riders don't deploy many of them — one or two Root Riders plus a larger wave of Super Goblins or Super Witches is the common pattern. The Root Rider does the "wall removal" that Earthquake spells did at TH11–TH14.
Giant Bombs and Multi Bombs placed underground — on the approach paths Root Riders most commonly take — deal significant damage when a Root Rider surfaces. Place Giant Bomb clusters around your DE Storage and DE Drills, not on the outer ring where Root Riders arrive. Root Riders surface beside defenses, not beside resource buildings, so the path from a defense to your DE core is where traps matter most.
Your Scattershots also deal ground damage in addition to air damage — position at least one Scattershot where its ground splash covers the area around your DE core.
The most efficient TH15 farming army uses Root Riders to clear key defenses, then Super Witches to flood the resulting gap with Skeleton swarms. Multi-mode Inferno Towers are essential in the core to handle Skeleton groups — without multi coverage, Skeleton swarms reach your DE Storage before defenses can clear them. Position your multi-mode Infernos where they cover the spaces between your DE Storage and any defensive wall gaps a Root Rider might create.
Most active TH15 players operate in Legend League — the fixed daily loot bonus becomes very efficient at this level, and base design in Legend matters more for maintaining trophy counts than for loot protection. Browse TH15 farming bases for layouts that handle Root Rider approaches while also defending well enough for Legend League. For war, use a dedicated TH15 war base.
How do Root Riders attack in farming raids at TH15?
Root Riders burrow underground and surface beside defenses, ignoring walls. In farming attacks, one or two Root Riders clear key defenses, then Super Goblins or Super Witch armies flood through the gap. Unlike Goblin Knife which relies on Earthquake spells, Root Rider attacks bypass walls entirely — trap placement replaces compartment design as the primary counter.
Where should I place Giant Bombs to stop Root Riders in a farming base?
Around your DE Storage and DE Drills, specifically on the paths Root Riders take after surfacing from clearing an outer defense. Root Riders move toward defenses, not resources — so the path between your outer defenses and your resource core is where underground traps deal the most damage.
Do walls still matter in a TH15 farming base given Root Riders?
Yes, but less than before. Walls still stop Super Goblins, regular Goblins, and Witches — they just don't stop Root Riders. A TH15 farming base uses wall layers for non-Root-Rider attacks while relying on traps for Root Rider paths. Both are needed since not all farmers use Root Riders.
Is Legend League better than traditional farming at TH15?
For most TH15 players, yes. The fixed Legend League loot bonus (including significant DE) combined with not needing to find good raid targets makes it very time-efficient. If your defenses hold most attacks to 1–2 stars, stay in Legend. If you're getting 3-starred often, drop to Titan League and run a farming base there.
What's the most resource-efficient farming army at TH15?
Super Goblin + Earthquake remains efficient. For richer hauls, Root Rider + Super Goblin armies can break into better-defended bases. Root Riders cost no additional resources to boost if you already have them researched — making them effectively free wall bypasses for farming armies.
