Ultimate Trial

Ultimate Trial combines Build & Research with Training Speedups culminating into the conclusion of the Global Ace Commander event. 

As it matters in Build & Research, you want to construct buildings and do research that will yield you the most Might, since Might is how your points are calculated. For each point of Might you achieve in this fashion, you are given 7 Points in the event. In the Training Portion, training and promoting your units to the highest Tier you can will give you the most points. You will want to get at least 6 million points altogether to get all rewards.

However, like all Global Ace Commander events, just getting to the maximum Phase points to give you your personal rewards will not get you ranked overall, to do this you must exceed them.

Placing in at least the bottom 25% overall—that includes all Global Ace Commander events combined—will get you Obsidian Frags.
