Okay, after the healing in my post, Aridha is at 2 1st level slots. She has 18 HP before using HD during the rest.
So I think I discovered one of my delays, and the good news is there's an easy solution. Hee hee. I am a little embarassed, but I have been lazy and keeping track of hit points and spells and so on on a Notepad sheet...and I realized that I've been doing a terrible job at it. So I've been having to go back page after page, reread posts, keeping a tally...and it's such a pain that I've been avoiding it. Which is lame, however, I will from now on keep the tally in each post, which will mean I won't have to do that and that will mean posting is not such a huge mess for me. Wee!
Laziness is a terrible thing. I'd stop, but it's so much work!
(^_^)
So, I'm gonna roll for 2 hit dice here during her rest. [roll0]
Now she healed both Tolan and Dent. Sorry, Damien...Aridha can tell who's more badly hurt.

One was healed for 20, one for 16. I lost track of who was more badly hurt, so whoever was more badly hurt got the 20 (her first spells), the other got the second spell for 16.
A short rest doesn't let her recover spell slots, but it does renew her Wildshape, so that's something.
This is trickier than I expected! Wild shaping is a great option for combat, but it means she can't heal anyone but herself anymore...and healing herself is substandard since she loses her Wis bonus (though it's nice as a bonus action). I apologize for the bumps as I try to find this character's niche. She's built as a kind of hybrid melee/support caster, and I haven't found the right balance yet.
Thanks for your patience, and if anyone has suggestions/ideas, they're more than welcome!
