Hi. Shadowheart just got downed in a dungeon and I have tried using a healing potion on her (with my main( and I have tried to revive her with a scroll but neither work. Furthermore I cannot long rest since it says one of my characters are incapable of moving (makes sense). She have made 3 successful deathsaves and is just lying there

Anyone knows what I am supposed to do to get her up on her feet?
Thanks!
Downed characters get picked up with the Help action (brown icon of hands clasping.
The Revivify Scroll is used when the character is dead.
You can (and should) also use the Help action in combat.
