So, one of my players is interested in this power, because from what we understand, it basically allows you to vanish from the enemy's sight for one round, provided you're in their line of sight and in short range or closer.
This means he can disappear, and then surprise the enemy, correct?
Also I'm having trouble finding rules in the book describing surprise, as in when you attack someone and they are completely unaware of it.
But, the description says it can't be activated multiple times. Does this mean you can only do it once per encounter? And if not, how often?
