Skill for the Assassin class has issues with attacking targets while you are near your enemy.
The stigma skill Dash and Slash is a 2 time repeatable skill.
Example: When I use the stigma skill called dash and slash, it will sometimes say on screen, "There is a obstacle in the way!".
Also Stella Laboratory 3rd boss (Bronze Guardian) / Assassin cannot Ambush or Dizzying Ambush the boss. Gladiators AoE's cannot damage this boss either.
