"I'm good with calculation." Trophy in LEGO Batman: Legacy of the Dark Knight

Maintain Max Stud Combo for 60 Seconds

Bronze trophyBase game

Keep the stud combo, the meter beside your stud count, top right, from dropping back to 1x for 60 seconds. Any multiplier from 2x up counts.

Smash your way through Chapter 1's Iceberg Lounge level once the rooms with security cameras begin, as for "Never do it for free.". Hyper Combo and Stud Combo Duration, in the Exploration tree, make the meter easier to keep up. A cutscene that starts while the combo runs does not break it, which can carry you to the 60 seconds.
