Mortal Shell II — Ballistazooka Location (Sentry's Grave Dungeon)

The Ballistazooka does not do subtle. This heavy sidearm launches giant explosive bolts that detonate for area damage — devastating against packed groups and staggered elites, and expensive enough with Resolve that every trigger pull is a commitment.

Where to find it

1. Fast travel to the Gate of Mammon Beacon and head north-west.
2. Climb the first staircase into the building's ground floor, then circle the structure clockwise into its interior.
3. Take the stairs down into the Sentry's Grave dungeon.
4. Fight through to the end and defeat the mini-boss — the Subjugated Guardian. The Ballistazooka is yours automatically when it falls.

What it plays like

• Real area damage. The explosion hits everything near the impact — groups, pairs, and any enemy hiding behind the one you aimed at.
• Resolve-expensive. This is the price of the power: the cost per shot is the highest among sidearms, so spamming is not a strategy. Land swings with your primary to refill, then spend big.
• Executioner's tool. Its best role is ending wounded elites and scattering reinforcements the moment they cluster — one bolt converts a messy brawl into a series of duels.

Bring it to fights with adds and thank yourself later.
