The Borsodi auction-house heist has several choices, but the most important are your safecracker, climbing expert and which brother you support inside the vault. This page keeps each decision separate so you do not lose a one-time collectible.
Quinto opens the vault quietly but triggers a monster-trap encounter. Casimir Bassi uses an explosion, which changes the hostage standoff. Eveline is the available climber; Hugo Hoff is already dead when found. Siding with either Borsodi brother still lets you collect the Viper Venomous Steel Sword diagram in the vault.

Heist crew combinations
Choose a safecracker and review the outcome. Both climber routes eventually resolve to Eveline.
| Position | Option | What changes |
|---|---|---|
| Safecracker | Quinto | Picks lock; trap with monsters activates |
| Safecracker | Casimir | Explodes door; changes the standoff |
| Climber | Eveline Gallo | Helps the party enter |
| Climber | Hugo Hoff | Unavailable: he is found dead |
| Final allegiance | Ewald or Horst | One brother survives; casket negotiations differ |
