Apply Shadow Shifter to evade for 1-hit KO body touch or skills

Description of Suggestion:Shadow shifter to avoid 1-hit KO body touch or skills, especially from boss (eg. emp dark genesis, shinsoo body touch, vl eye laser) Why Do You Think This Is Needed? Currently, skills like shadow shifter are good which mainly to help the character to stay in position while mobbing or bossing. However, with this addition, it would make the skill more relevant to the jobs with this skill (Night Lord and Shadower). As the % of shadow shifter is not 100% (NL 40% at level 40 and Shadower 50% at level 40), player may not risk to not avoiding the hit. It just for additional chance to survive when they are being hit. Possible Downsides or Obstacles: The current 1-hit KO mechanisms may be hard to be adjusted as they have been programmed to minus 100% hp instead of a fix damage where avoiding is still possible. May need your expertise for advise or implementation of this suggestion. Additional Notes/Comments: Currently, NL and Shad are being favoured in boss run as they do not have any party buff and dpm does not scale as high as other dpm jobs. Hopefully this may be considered to be approved for better gaming experience of these jobs.
