Treat Wounds DC

[orphias]

When you Treat Wounds do you roll against a DC of your choice, or do you heal hp's based on the skill check you roll?
EG, Base DC 15, expert 20
Do you roll the check and heal hps based on the DC you reach, or do you need to state the DC you are rolling for ? For example you want the extra 10 hps for an expert heal so if you roll 16 on your check do you fail and heal nothing, or do you still heal 2d8 hps because that succeeds against the DC 15 ?

You have to declare beforehand if you do base or expert.

So if you declare expert and roll a 16 then you heal nothing. If you declare expert and roll a nat 1 you might actually critically fail even with a skill >10.

On the other hand - if you declare base and roll 26 you do gain a critical success of 4d8 which might be more as expert 2d8 + 10.
