Zora Jilkina:
Guess I didn't need that spell after all. Going to update resources, do I lose the spell slot for that command?
Nope, you should have used just 1 level 1 slot so far.
Zora Jilkina:
First, I forgot to put two domain spells I get at level 3 on my sheet. Shatter and gust of wind. Could you add them? Can they be available this fight?
Yup, good catch, I can add them. They're available during this fight.
Zora Jilkina:
Second, assuming shatteris available, how many birds can I catch with it assuming a sphere that misses my companions, especially morg! Those bird were no joke to him?
They're small birds and pretty well engaged with Morg. It would be pretty much impossible to use Shatter and avoid hitting Morg and/or others engaged in melee with the birds.
