That is probably the issue. The skill doesn't list any vim drain on my screen or in the wiki; but it does have a BLANK location where one could be listed if it appeared at a higher level. So if it is starting out draining my vim then the problem is likely an interface issue rather than a problem with the skill itself.
I'll check for a change listing a negative vim "heal" in the upper left hand corner of my screen next time I try the skill out and see if an otherwise unlisted drain is being added on. It wouldn't have shown up AFTER the skill shuts down which is when I've been hunting for anomalies in the log, rereading the wiki, and checking the skill description for an explanation and I wouldn't have found such an issue when I was assuming it was a problem with "running" or with heals counting as a "Rest" or anything else in the skills listed description.
If it shows up then the solution is to simply not use this as a sustain that I expect to remain active between battles and to turn it off manually at the end of each encounter. Thanks!
