A couple of things:
-YES it is a WIS save
-Frightened does NOT mean you have to run away, unless the specific fear effect states it.
-Frightened does two things , firstly, you cannot APPROACH that which you fear, secondly, you have disadvantage on your attacks so long as you are frightened. (Basically the opposite of faerie fire in that respect)
-SO, Mina and Daedarai can still attack, but only from range and at disadvantage unless they can use a spell such as viscious mockery or somehow gain advantage.
-Daedarai, you are hidden, so you have advantage, which willnegate the disadvantage.
-Keep in mind guys, the hags fear effect and the save youneed to make only happen at the START of your turn, thus if the hag dies BEFORE it's Daedarais turn, then he never needed to make the save.
-Finally, Trogdor mate, minor thing, your wording of the phrase 'inspiration'. Did you spend your inspiration? I posted earlier that you, as a halfling have advantage vs fear effects anyway. You may have missed it, which is cool. So, you don't need to spend your inspiration! You're just naturally hardcore like that. This is why halflings make amazing fighters.[/sblock]
