Moonlighter 2 Sergeant Roberto Miniboss (Treasury guard)

Sergeant Roberto, the Treasury guard, is one of the two minibosses on Moonlighter 2's The Gallery – Treasury Halls floor. It appears at the halfway point of the run and drops Gallery rare material.

Where you fight it

  • Title: Treasury guard.
  • Floor: The Gallery – Treasury Halls.
  • Appears at the halfway point of the run, before the floor boss.
  • Drop: Gallery rare material (used for that dimension's early weapon upgrades).

How to beat it

Sergeant Roberto spawns with two or three helpers. Kill the helpers first: taser and stun effects wear off much faster on the miniboss itself, so clearing the adds makes the crowd control stick.

Elites and minibosses do not enter the Rupture state, so the backpack throw only works on their adds, not on the miniboss.

Drop

Sergeant Roberto drops Gallery rare material.
