Certain skills share effects between classes in order to prevent them from stacking, or they trigger shared cooldown effects which prevent the skills from being used back-to-back against the same enemy.
The following table summarizes these effects. If only primary effects are listed, then these skills cannot be stacked (applied at the same time to the same enemy). If a secondary effect is listed, then these effects also cannot be used back-to-back as the secondary effect blocks re-application of the primary effect.
Note that the durations listed in the following table are defaults. These durations could be modified by traits or Legendary Item Traceries (see each skill for details).
