The Trial of Balance is a Trial of Eternity introduced in the Trials of Gnomus DLC of Plants vs. Zombies: Garden Warfare 2. The objective of the trial is to make it across a series of platforms suspended over a lava pool. This trial can only be accessed with the Green Key of Agility.
The player has to cross many different platforms, including small circular platforms and long winding platforms suspended over a lava pit. Along the way, there are projectiles and giant hammers that can vanquish the player. Being vanquished, by either falling into the pit or getting hit by a projectile or hammer, will result in immediate failure of the entire trial.
The Imp can easily beat this trial due to his double jump.
Citron is a good for this trial due to his Citron ball.
