There are plenty of collectibles in Tiny Tina’s Wonderlands, spread out through the various areas you will explore. Scrolls are similar to the ECHO Recordings found in the older Borderlands games, as they offer some kind of insight to the game’s world. This page will detail the Scrolls found in the Drowned Abyss area.
Scroll - Unheeded
Start at the Untrodden Depths Fast Travel and follow the path along to the northeast until you see a gap in the wall which is covered by vines. Melee it to gain access to the cave, then look behind the waterfall to find the Unheeded Scroll.
Scroll - Climbing The Ladder
Progress through the Of Curse and Claw Side Quest until you enter the Temple of the Slithersong, then look behind the brazier to the left of the entrance to find the Climbing The Ladder Scroll sitting on the floor.
Scroll - Consequences
Head to The Seapulchre from the Untrodden Depths Fast Travel, then hug the right wall until you reach Dud’s Thud. Here you’ll want to continue to follow the path along to the west until you reach Oncewet Court, then head up the stairs on the right and look behind the waterfall to find the Consequences Scroll.
