Overall difficulty

Both interface and overall gameplay difficulty of Dual Randomness is similar to the previous events Polarized Light. The event offers normal and hard difficulty, with the way the event is laid out, players can obtain the hard mode reward by simply defeating the first level of the hard mode story node. Normal difficulty can be completed with lv80+ 4x expansion T-Doll echelons with decent graded equipment and fairy/HOC back ups, while hard difficulty test the players' echelon level, role diversity, HOC levels and specifically for chapter 2, Coalition echelon levels.

New elements and mechanics

Repeatable story nodes to progress story

All event chapters are on display on a single side scrolling menu, a counter can be seen on the main combat node of each chapter, informing the player the progression of the chapter. Unfortunately both the normal and hard version of the combat node shares the same counter, the counter will register the highest progression only, meaning that switching difficulty nodes will not move the overall chat progress. Chapter 1 combat node has five stages, chapter 2 has nine, chapter 3 also has nine.

Chapter 1 will be notated as E1, normal combat nodes of chapter 1 will be named as E1-1 to E1-5, hard combat nodes of chapter 1 as E1-1EX to E1-5EX farming node of chapter 1 will be simply named E1.1, and so on.

Repeatable farming nodes of each chapter

When the counter for the main combat node reaches max value, the player can then progress to the next chapter, however a 'farming' node is also unlocked. The farming nodes will be marked as E?.1, the farming node will contain a selection of limited edition dolls available for looting, as well as the chapter specific newly introduced dolls of this event.

Branched out story only nodes

As players progress through the main combat node, side story nodes will start appear underneath, those are story only, but completion will yield some item rewards.
