How to Get Mortar

Reach Level 75 to unlock Mortar for placement, then purchase it from the Store

Alternatively, buy the 395 Robux gamepass to place it before reaching Level 75

Is Mortar Worth It?

Strong splash damage that can hit many enemies clustered together

Relatively cheap for a cliff tower with this much damage output

Cluster bombs at Level 4+ add extra unlisted splash damage around the main impact

Requires a cliff to place on, so it's not usable on every map, and its slow projectile speed means fast single enemies can be missed

Best Loadouts With Mortar

Great alongside Ranger or other cliff-based towers on maps with elevated terrain

Works well with Hidden/Lead detector towers since Mortar itself has no Hidden detection
