The Lavis Cannon (Japanese: ラヴィス＝カノン) is a rare saber-type weapon in Phantasy Star Online. It is very similar to the common saber excluding its color (which is a lighter blue than a Brand) and the section near the the hilt which is distinguished by a cone.
This weapon can only be found as a drop in the ultimate difficulty, and each section ID has a specific enemy they can hunt in order to obtain this item. The section ID that has the best chance of obtaining Lavis Cannon is Redria by hunting the rare Pouilly Slime in the Caves. All drops are listed below:
| Section ID | Ultimate |
 |
Sinow Red (Mines) |

Morfos (Seabed) |
 |
Sinow Red (Mines) |
 |
Pofuilly Slime (Caves) |
 |
Tollaw (Forest) |
 |
Pouilly Slime (Caves) |

Monster drops are not the only way to find the Lavis Cannon, however. If a Hunter that is at least level 100 combines a Double Cannon with Syncesta, the Lavis Cannon can be synthesized. All of the attributes from the original Double Cannon will be transferred over to the resulting weapon.
Lavis Cannon can be only be equipped by members of the Hunter class. When its special attack is used on the enemy, the weapon consumes 5% of the equipper's HP in order to launch a wave directly in front of it that appears visually similar to the Handgun or Rifle shot.
If a Hunter with at least 850 ATP combines a Lavis Cannon with Syncesta, the Lavis Blade can be created.
