Use "/crests" to find out the status of each of your gear slots towards the achievements that allow you to trade up crest levels.
By default, shows the slot only when it is unmet for the current achievement in progress.
"/crests help" ("/crests ?") shows a basic usage message along with a mini-explainer on the weapons slots. Weapons are a little spammy until you've satisfied the requirement, because there are five different slot values that are all relevant, though what you need is only to have either a two-hand weapon or both your main hand and whatever you use in your off-hand slot.
"/crests verbose" ("/crests v") shows the info for all of the related achievements for the current season, and a slot still needing to reach a lower bar isn't repeated for higher achievements.
Original credit to some long ago Wowhead comment by kanegasi which gave a /run command that I've been modifying as item levels changed. Finally made this because it's more useful across my alts.
