First, I want to say this system has awesome potential and I know that 5E is a work in progress. Being a developer myself I understand project priorities and offer to help in any way that I can. I have looked through the Release Candidate build and I get a great many errors when operating through the spell library or when casting a spell then altering it from the pop ups. It would appear that attack roll spells are still not quite supported. I have also noticed that on hit effects such as Mummy Rot or Cockatrice bites to call for a save and/or apply a condition to target are not currently supported or is there a work around for this? Multi-stage Saving throws are a thing in 5E but other than pulling an ad hoc I don't see a way to do these either, is this on the radar? One thing I have noticed, and this may just be the learning curve and scarcity of current documentation on the subject matter, is that there is not a reliable way to get 5E saving throws dynamically as of yet. I can get Fireball to work but it would appear that unless I hard code the DC I have not idea what the system generates. I would like to be able to DM whisper that or log the output of a script if possible to allow me to troubleshoot issues I may have. At least in this way my trial and error can have some direction. I have gone through a lot more videos and articles over the past few days and although they are helpful in navigation they are either out of date or designed for PF/3.X systems which is sufficiently different from 5E to not be that helpful. Additionally, resistance and immunity need to have a bypass mechanic like the 3.X/PF DR. Criticals and vulnerability work differently as well, which so far as I can tell has yet to be implemented.
