Hi Everyone, I'd like to create a series of conditions to have my Rogue use vanish when 20% hp is reached and "reset" himself. Currently: 1) Engage Target 2) HP (Me) Reaches 20% 3) Cast Vanish 4) Target resets (Evade) 5) Rogue chases evading monster continuing attack -------- Are there any conditions that I can utilize to "End Combat" or reset? Looking to complete this using "Conditions" please. Thanks! -AutoBot3000
