DC for a First Aid Heal check is 15. Gnoll 4 continues to die.
[sblock=OOCDC for a First Aid Heal check is 15.
A successful Aid Another Check (DC 10) would give you a +2 bonus on this check.
A healer’s kit gives you a +2 circumstance bonus on Heal checks.
You may continue to try again until successful, or the gnoll dies.
To speed things up:
Gnoll 4 is the one at the edge of the clearing. Will not stabilize naturally. You have 3 attempts to stabilize ( 3 rounds/18 seconds) before it dies.
Gnoll 3 is the one outside the front door. Stabilizes naturally in Round 12.[/sblock]
