DWAARPIcon "Rrrready to rrrrumble!"
The DWAARP, short for Drilling Weaponized Auto-Attack Rumble Platform, is a Level 4 Dwarven Bombard in Kingdom Rush: Frontiers. It creates localized earthquakes that deal damage to enemies and slow down them by 60% for 0.4 second in its area of effect. Its single-target DPS is low but it compensates for this with its wide area of effect, dealing damage to all grounded enemies in its range.


"The pinnacle of dwarven mining, its quakes damage and slow all enemies around it."

Forgoing the cannons of the basic towers, the DWAARP instead uses a giant mining apparatus as its primary weapon, dealing damage to all enemies in its range. However, it possesses terrible single-target DPS, the lowest among the advanced towers, and even lower than the Level 3 Dwarven Howitzer, making it ill-suited against individual targets with high armor or HP.

Compared to the other Level 4 Artillery Tower, the Battle-Mecha T200, the DWAARP is better against large numbers of spread-out enemies (especially when it covers multiple paths) due to its much wider range. However, it is less effective against more durable enemies.

  • The DWAARP is good against waves with a large or concentrated number of enemies, as it will be able to output huge amounts of damage and clear out weaker foes. Try to place the DWAARP on strategic points where the tower's range fills the entire path; especially curved or circular paths or choke points.
  • It is excellent at attacking and slowing the various hound enemies - Sand Hounds can be killed instantly while War Hounds are damaged significantly. It is also extremely effective against Jungle Matriarchs - any Spiderlings are killed in one hit, and similarly, it can counter Sand Wraiths - with sufficient track coverage, it can destroy unlimited numbers of Fallen while damaging the Wraith itself.
  • It is very effective against invisible Saurian Nightscales, as it can hit them with collateral damage.
  • Furnace Blast is one of the most powerful upgrades in the game, and is absolutely worth upgrading. At Level 3, it deals a whopping 200 True Damage over 4 seconds to every single enemy in range, killing any weaker enemies and damaging even heavily armored ones.
    • Note that the Crossbow Fort's Falconer does not increase the range of this skill. While Falconer is a very strong buff for the DWAARP to have, it may end up wasting Furnace Blasts. This is because the ability is activated as soon as an enemy enters the DWAARP's normal attack range, which when buffed by Falconer, extends past Furnace Blast's area of effect.
  • Core Drill is the only guaranteed Instant kill upgrade among regular towers, and is useful for mitigating the DWAARP's weakness against bigger enemies.


  • The DWAARP is completely harmless to flying enemies.
  • The DWAARP is the most expensive tower in the game, with a total cost of 1065 Gold. Its special abilities are also very expensive, costing 800 gold each to max.
  • The DWAARP's horrendous single-target DPS (the lowest amongst advanced towers) makes it lose much effectiveness against enemies with high armor or HP.
  • Core Drill is not reliable as a counter against strong enemies, as it targets the enemy closest to the exit. This will often be a faster enemy, which normally has a low amount of HP, making it a less desirable target. Furthermore, unlike the Arcane Wizard's Death Ray and the Musketeer Garrison's Sniper Shot, Core Drill cannot be cancelled if its target dies, wasting the ability.
  • Lycans in human form and Immortals are not instantly killed by Core Drill. Lycans transform into their werewolf form and Immortals turn into Fallen.


  • Core Drill has a wider range than the DWAARP's normal attack.
  • Although Bloodshells are immune to artillery damage, Furnace Blast still work on them.
