Does the Assassin get some type of stealth skill?
– Yes. The Scout class gets the skill Hide I (lvl. 5), which is the Aion equivalent of “stealth”, allowing both Assassins and Rangers to use the initial rank. Assassins however are the only ones which obtain Hide II (lvl. 34), which is much more difficult to detect, and lasts slightly longer. Are there any abilities that can only be used while Hiding?: – NO. As of now there are no abilities that are performed exclusively while in Hide mode, or any special damage/crit or other bonus for attacking while in Hide mode. Furthermore any ability used while in hiding will take you out of hiding.
