The Trial of Recollection is a Trial of Eternity introduced in the Trials of Gnomus DLC in Plants vs. Zombies: Garden Warfare 2. The Trial of Recollection can only be accessed by going through the Blue Door, which in turn can only be unlocked with the Blue Key of Recall.
The player will pass through many rounds, a round comprising of a gate which has a sequence on it, and then many panels. The objective is to jump on the panels in the same order as the sequence on the gate. Failure to jump onto the right panel or falling and getting vanquished immediately results in failure of the entire trial.
The player must complete the trial in 1 minute and 8 seconds.
Try to move forward continuously to maximize time usage while allowing yourself to remember the sequence. It might be a good idea to use Rose, Super Brainz, or the Imp, as they have they have high jumps that have room for error. However, Super Brainz is relatively slow, so it might not be a good idea to use him. It might also help to have a friend next to you, because when the number of pictures increase, you could have your friend memorize one half while you memorize the other.
