"Secret"/Useful knowledge
It only recently became clear to me that Prof X's dexterity 2 colours (blue and basic yellow) have actually a meaning, namely if it's blue, you reduced the timer of the falter cooldown by a second every time it pops up, and when it's yellow, you can heavy charge to set it on cooldown again. This is a nice visual cue to respond quicker when it's ready to use again. I can't keep my eye on the top left side every time in the midst of a battle.
Do you guys have some info that not everyone knows but might be very useful to know?
