I think I can help you Snowline
What you are asking for is a sort of IF statement that would use Ancestral Balm III if it was available and regular Cure if not.
However, although you can think of click to cure as a sort of "whack-a-mole" game (click detriment, they will go away). If you were to click the trauma icon when there is clearly an arcane, the result is the same. You would cast "Cure" and the detriment would be removed.
In the Profit_Cures.txt
<Data Name="Mystic" TraumaCure="2945678992" ArcaneCure="2945678992" NoxiousCure="2945678992" ElementalCure="2945678992" CurseCure="969542071"/>
What you could do is switch one of these with the code for Ancestral Balm III
which is
340840254
So for example, regardless of which detrimentals are applied, you could always go for TRAUMA icon when possible and if Ancestral Balm is not up, you can click any of the other 3.
I hope this is a valid work-around for you, I am going to try it myself and get back to you.
I can confirm this works.. its just a matter of remembering to hit trauma (or whichever you choose) instead of the others!
If you want to cure trauma normally.. just remember to click noxious, arcane, or elemental.
Is this any help?
