How to say "challenge" or something similar?

In my homebrew D&D setting, I use the Dragon Language as draconic as much as possible. A dragonborn (dragon-people in D&D. Not nearly as cool as someone who eats dragon souls) nation's religion names stuff in draconic, and I'm trying to figure out how to name one of their holidays.

The translation should loosely mean "Day of the Trial", "Day of the Challenge", something like that. Sul do faal Grah, "Day of the Battle", is the closest I've managed with the translator that doesn't sound too weird. I was wondering if perhaps there was a better angle that I was missing, though, perhaps some roundabout way of saying challenge?
