Dragon Gauge is Dragoon's Job Gauge.
Dragon Gauge
Upon learning the trait 
Life of the Dragon at Lv. 70, you will be able to view the Dragon Gauge, which displays the strength of the first brood's Gaze. Their gaze is strengthened by performing the action 
Mirage Dive.
When 
Geirskogul is used at maximum gaze level (two units), Life of the Dragon will activate automatically. This will allow you to execute several powerful actions such as 
Nastrond and 
Stardiver (acquired at level 80). The Dragon Gauge will display the remaining time in seconds for Life of the Dragon. This starts at 20 seconds, but increases to 30 seconds upon learning 
Life of the Dragon Mastery at Lv. 78.
When you learn the trait 
Lance Mastery IV at Lv. 90, 
Raiden Thrust and 
Draconian Fury will sharpen the Firstminds' Focus, which is indicated by the purple "scale" icons. When sharpened to maximum (2 Firstminds' Focus obtained), you can execute the action 
Wyrmwind Thrust, which will consume the Firstminds' Foci.
