The Assassin's Guild is a Level 4 Melee Tower in Kingdom Rush: Frontiers. It is unlocked in Stage 4, Dunes of Despair. Assassins rely on speed and stealth rather than strength to fight their enemies.

They regenerate 40 HP per second when not in combat.


"Trains agile and deadly Assassins to ambush and rob enemies."

Assassins are relatively fragile compared to their counterparts, the Templars, possessing only 200 base HP and no armor. They rely on their base 40% dodge chance (which can be improved through their Counterattack ability) to survive.

When fully upgraded, they become very capable at stalling enemies with their evasive abilities, and can fight even the toughest foes, dealing True Damage and having a small chance to Instant kill with their Sneak Attack. The Pickpocket skill also allows them to generate some extra income.

Assassins become invisible when idle, meaning that ranged enemies can't target them unless they're engaged in combat.

  • Same range as Level 1 through 3 Barracks and Knights Templar. 


  • Assassins are agile, versatile units good at dealing with all kinds of enemies. They can kill weaker, lower-HP enemies efficiently with their solid DPS output. Against stronger enemies who deal high damage (but don't have an area attack), such as Bloodshells, Bluegales (in melee combat), Werewolves, Lycans, and Executioners, Assassins' dodge chance allows them to survive for extended periods of time. Their true damage and small instant kill chance is also useful in defeating enemies with high armor or HP.
  • Assassins cannot be targeted by ranged attacks while idle. However, they become vulnerable to these whilst engaged in combat, as they have relatively low HP and no armor, and can't dodge ranged attacks. Good micromanagement is required to make them effective against ranged enemies.
  • Upgrading Counterattack to Level 3 should be a priority, as it doubles the EHP of Assassins and more than doubles their DPS, and is relatively inexpensive.
  • Pickpocket only provides value if upgraded in the earlier stages of a level, as it takes some time to repay itself, depending on how actively engaged in combat your Assassins are. In almost all cases, it is not worth upgrading it to Level 2 as this significantly increases the repayment period.
  • Assassins are stronger than Templars in most scenarios, dealing far more damage, killing low-HP enemies more efficiently, offering similar survivability against high-damage enemies, and having more cost efficient upgrades. They are only worse when being attacked by range enemies or enemies with area attacks; when they can't utilize their dodge chance.
