i was originally let down by this but the following has tuned up
Legendary cloaks are confirmed! They seem to be a requirement to use another item, see the strings section.
Spirit of Chi-Ji - Your healing spells also grant the target the Spirit of Chi-Ji, which heals the target for 3% of their missing health, every 1 sec, for 3 sec.
Flurry of Xuen - Your damaging attacks have a chance to trigger a Flurry of Xuen, causing you to deal 60% weapon damage to all targets in front of you, every 0.5 sec for 3 sec.
Essence of Yu'lon - Your damaging attacks have a chance to empower you with the Essence of Yu'lon, causing your next direct damage spell to also burn the target with jade dragonflame, dealing 5,000 damage and an additional 30,000 damage over 6 sec. This damage also affects other enemies near the burning target.
Endurance of Niuzao - The Endurance of Niuzao fully absorbs the damage of one attack that would normally kill you. This effect has a 60 sec cooldown.
