Kingdom Rush Frontiers Tips: Towers, Heroes & Farming 2025

Updated: 16 Aug 2025

Author: Arcane Forge Team (300+ hours across KR titles). This guide focuses on Frontiers campaign & endless modes.

Early Game: Clean Openings

  • Dual-Archer starts into Rangers Hideout is the most forgiving line on maps with split lanes. The passive Poison Arrows carries low-armor swarms.
  • Reinforcements + Rally kiting: place reinforcements in front of your first choke to buy 3–4s for cash ticks before your first upgrade.
  • Gold efficiency rule: if two adjacent tier-2 towers are an option, prefer one tower to tier-3 first—Frontiers punishes wide, low-level spreads.

Best Towers & Upgrade Paths

Archer → Rangers Hideout

Go T2 ArcherT3Rangers. Prioritize Poison Arrows 2/3 early; Wrath of the Forest is S-tier crowd control for split paths.

Artillery → DWAARP

DWAARP outclasses Tesla on most maps because Furnace Blast shoves enemies back into kill zones. Get Core Drill if armored elites stack.

Mage → Necromancer Tower

Against sustained lanes, Necromancer skeletons act as disposable blockers. Skill order: Horde 2/3Infection 1/3Horde 3/3.

Barracks → Assassins Guild

Assassins (with Smoke Bomb) excel at delaying medium packs. Use at side lanes where artillery splash can connect.

Hero Picks & Skill Orders

  • Alric: Balance Sand Warriors 3/3 with Rage 2/3; he is your bruiser for choke anchors.
  • Ashbite: Path into Infernal Combustion—synergizes with DWAARP to loop knockbacks.
  • Nivus: Max Arcane Nova first for burst clears on split paths.

Map-Specific Tips

  • Buccaneer’s Den: Use Pirate Watchtower for map control; add Rangers to pin sea lanes with poison ticks during ship spawns.
  • Dunes of Despair: Armor stack → rush DWAARP + Necro; funnel with reinforcements before the double bend.
  • Temple of Saqra: Boss phases are add-heavy—save Rain of Fire for statue spawns, not the boss itself.

Farming & Endless

For stars/cash grinding, community-favored loops remain Bonehart unlock paths and mid-campaign maps with short waves (try Snapvine Bridge). Endless: lean on Wrath of the Forest + Furnace Blast to force perma-clumps.

Common Mistakes

  • Over-investing in early barracks instead of poison/CC.
  • Skipping Furnace Blast—it’s your best scaling control.
  • Not repositioning rally flags; move them between waves to pre-soak assassins and conserve lives.
