The Tricorner district in Lego Batman: Legacy of the Dark Knight hides a set of Batcave Trophy collectibles shaped like Sand Timers (often called hourglasses). Tracking them down feeds directly into the "Quite the collection, Master Bruce." trophy for displaying every Batcave Trophy back at the cave.
What the Tricorner Sand Timers are
Each Gotham district holds a themed set of small collectibles that build into a single large Batcave Trophy. Tricorner's theme is the Sand Timer. Collect all 20 in the district, and the assembled trophy becomes available to place on a customization plate inside the Batcave.
Sand Timers are part of the wider Batcave Trophy collection that also includes one trophy per main story mission. Finishing every district set plus every mission trophy unlocks the "Quite the collection, Master Bruce." achievement.
Requirements before hunting them down
Sand Timers are scattered across rooftops, alleys, interiors, and elevated platforms throughout Tricorner. They will not all show on the map until the district is fully revealed.
| Requirement | Why it matters |
|---|---|
| Batgirl unlocked | Her Hackarang is needed to activate district Towers, which reveal map icons including trophy markers. |
| Tricorner Tower activated | Reveals every Sand Timer location as a trophy icon on the Tricorner map. |
| Glide and grapple traversal | Many timers sit on rooftops, ledges, and vertical structures around Tricorner's dense skyline. |
| Open-world access | Free roam of Tricorner opens after the New Beginnings mission in Chapter 1. |
Batgirl becomes playable during the Chapter 4 mission "Batgirl Begins," so the most efficient route is to push through the main story until she joins the roster, then return to Tricorner to sweep up collectibles.
How to track each Sand Timer
Step 1: Travel to Tricorner and locate the district Tower. Switch to Batgirl and use her Hackarang on the Tower's terminal to bring the district's map icons online.
Step 2: Open the map with the Options button and filter for trophy icons. Each Sand Timer in Tricorner appears as a small trophy marker once the Tower is active.
Step 3: Place a custom pin on the nearest unclaimed icon and fast travel to the closest SubWayne Station, then glide or drive to the marker. Trophy icons disappear from the map as you collect each Sand Timer.
Step 4: Check progress in the collectibles menu. Tricorner shows a counter that climbs toward 20 of 20 Sand Timers; the assembled Batcave Trophy unlocks once the counter is full.
How to confirm completion
Verification happens in two places. The Tricorner section of the collectibles tracker should read 20/20 Sand Timers. Back in the Batcave, the corresponding Sand Timer trophy appears in the prop selection wheel and can be placed on any customization plate.
If the count stops short, the most common reasons are an inactive Tricorner Tower (some icons stay hidden) or an unfinished interior segment behind a barrier that requires a specific character ability, such as Catwoman's whip, Robin's tech suits, or Batgirl's Hackarang. Switch characters at a fast travel point and revisit the marker.
Where Tricorner fits in the wider trophy hunt
Tricorner is the largest single-district collection in the game, with double the count of every other district. The remaining city districts each contain a 10-piece themed set.
| District | Trophy theme | Count |
|---|---|---|
| Tricorner City Area | Sand Timers | 20 |
| Old Gotham South | Dice | 10 |
| Old Gotham North | King Tut's Traps | 10 |
| Old Gotham West | Court Statues | 10 |
| The Cauldron South | Top Hats | 10 |
| The Cauldron North | Polka Dots | 10 |
| Newtown | Eyes | 10 |
| Gotham Village Robinson Park | Calendars | 10 |
| East End Amusement Mile | Joker Teeth | 10 |
Story missions also contribute their own Batcave Trophies, including Bonsai Trees in Infiltration, Surf Boards in New Beginnings, Disco Balls in the Carmine Falcone mission, Ace Cards in The Red Hood Gang, Cat Heads in Mimes, Rubber Ducks in The Penguin, Boomboxes in Flugelheim, Cakes in Joker, Coins in Two-Face, Kites in Kite Man, Venus Fly Traps in Poison Ivy, Spaceships in Firefly, Snow Globes in Mr. Freeze, and League Banners in The League of Shadows Returns.
Tips for working through Tricorner efficiently
Use Batman's glide for rooftop clusters around Sionis Industries and the Iceberg Lounge, where Sand Timers tend to sit on elevated air conditioning units, antennae, and ledges. Switch to a Batmobile for ground-level timers tucked into alleys and docks along the district's edge. When a marker appears inside a building, look for an unlocked side door, vent, or hackable terminal, then bring whichever character matches the access point.
Place pins liberally and clear icons in clusters of three or four before returning to a SubWayne Station. Combined with crime stoppages, AR Trials, and WayneTech Caches in the same area, a single sweep of Tricorner can knock out multiple achievements toward the platinum.
