I am in the process of figuring out what all I can do with the fancy new effects. Quite a few things are still unclear to me and maybe a wiki page with examples dedicated to this might be a good idea when it's released :)
Here is one thing I was wondering about:
The dragon soul feature that a dragon magic sorcerer has lets a power ignore a certain amount of resistance.
"Your arcane powers ignore any target's resistance to that damage type up to the value of your resistance."
Is there any way to do this using the new effects? I tried giving the target both a RESIST: 5 cold and a RESIST: -5 cold but they don't seem to cancel each other out.
Also I saw the RCHG effect in a screenshot on your blog, but it's not noted in the release notes. It could be that it was already in though :)
