"Swift and steady!"
The Watcher Arbor is the level 2 Archer Tower in Kingdom Rush: Origins.


"Watchers have excellent range and shoot with deadly precision."

The Watcher Arbor is stronger than its un-upgraded companion, able to take on average amounts of weak enemies, however, it cannot handle later waves of larger foes.

The Watcher Arbor can be upgraded to the Sentinel Arbor


  • This tower is good at flying enemies and high health enemies. just watch out for any armor-wearing enemies. If not strong or useful enough then it can be upgraded to Sentinel Arbor, since it is a better archer tower than this.
  • If there are fast enemies, archers towers can miss their targets, so use your soldiers and your reinforcements to support the archer tower by hitting their target.
