Under the healing scarab it reads, "A scarab restores 2 HPs. Three scarabs can get a broken PC back on her feet and five scarabs can heal a critical injury."
This confused me because my understanding is that if you're broken, you're on your feet once you regain one HP. If the healing scarab grants 2 HP, why does it mention that three scarabs can get a broken PC back on her feet?
I assume the five scarabs to heal a critical injury is just how many it takes to do so.
Can you use a healing scarab to regain HP if you aren't broken or is it considered first aid and once you're not broken, further first aid is ineffective?
