For reference: Does casting Aid stack? (No), What happens to the current hit points when Aid ends? (You lose the current hit points that you gained, effectively taking 5 damage).
My question is:
If I have a 2nd-level Aid spell that increases my current and maximum hit points by 5, then drop to 4 HP, and then have a 3rd-level Aid spell cast on me, what happens?
I see a few possibilities:
- I return the 5 HP I gained from my 2nd-level Aid, drop to 0 HP (and start dying), and then the 3rd-level Aid spell brings me back to 10 HP with no delay.
- My current Aid spell is simply superseded by the 3rd-level Aid spell, so the circumstances simply change to being granted 5 current HP to 10 current HP. Since I'm still due 5 HP, my current HP goes up by that value (now at 9) and I and never touched the Dying condition.
- Another possibility that you can explain.
Which of the above is true?
