Aspect of Mazzatun is a heavy armor set. When you take damage while under 30% Health, you heal for 7052 Health and restore 6020 Magicka and Stamina. This effect can occur once every 45 seconds.
This set can come in handy in case you drop low on health, and it is basically a failsafe set. The moment you drop below 30% health you will get a 7052 healing tick; this value can be increased with percentage modifiers and Champion Point perks like Blessed. On top of that you will also receive a huge sustain boost in case you drop low on Magicka or Stamina.
The Aspect of Mazzatun is part of the Shadows of the Hist DLC. The set drops in Ruins of Mazzatun in Shadowfen. Each set item is bound on pickup. You can acquire heavy armor, weapons and jewelry of this set in the Mazzatun motif style.
