As new general rules on damage rolls do not appear in the document, the rules on p.196 of the 2014 PHB would still apply, which is where 5e specifies that you can’t deal negative damage (be it with an attack, spell, or any other damage dealing mechanic).
Thanks! I don’t have my PHB on me (traveling for the holidays), but I was pretty certain that DnD had a “0 damage is not damage” and “negative damage is treated as 0” sort of rule, similar to Magic.
