Due to its damage boost offered to raid teams, Z'en's Redress has become a staple set whether it's on a support or DPS role.
Your Light Attacks apply the Touch of Z'en on enemies for 20 seconds. Enemies with the Touch of Z'en take an additional 1% more damage for each damage over time effect you've placed on them, up to 5%. You can only receive the benefit from one Touch of Z'en per enemy.
As a note, Z'en's Redress offers the 5% damage taken on a target to EVERYONE in your group. This is usually put on a non-Warden healer or a Magicka Dragonknight DPS as of the Stonethorn patch.
It's important to also note that while you can frontbar or backbar Z'en's Redress along with the various DoTs as well depending on your setup, your Light Attack that applies the Touch of Zen must have been from that specific bar. If you barswap as your Light Attack (if ranged) is still moving mid-air then the Touch of Zen won't apply.
So what constitutes as a Damage Over Time effect to fulfill the Z'en's Redress condition?
|Soul Trap & both morphs|
|Entropy & both morphs|
|Swarm & both morphs|
|Cripple & both morphs|
|Trap Beast & both morphs|
|Sun Fire & both morphs|
|Searing Strikes & both morphs|
|Fiery Breath & both morphs|
|Lacerate & both morphs|
|Twin Slashes & both morphs|
|Scattershot & both morphs (with BRP Bow)|
|Poison Arrow & both morphs|
Note that skills or things like Haunting Curse from a Sorcerer or Solar Barrage from a Templar may apply as a debuff or a delayed damage effect every specific interval but NOT as a damage over time effect.
AOE skills that do count as a Damage over Time effect (as evidenced by Thaumaturge working on many skills) but that do not apply an actual SINGLE TARGET DoT effect to targets do not count towards a Z'en's Redress DoT.
