PTS set questions.

Rex-Umbra

Looking to switch up my tank next update. Really like the idea of shadowy life stealing like a dark knight or death knight type class.

Wondering about these sets.

Grace of Gloom
(2 items) Adds 1206 Max Health
(3 items) Adds 4% Healing Taken
(4 items) Adds 1206 Max Health
(5 items) When you take damage from a single target direct attack or ability, you become a living shadow, causing your to heal for 1097 every second and gaining Major Evasion, reducing damage from area attacks by 25%. This effect can occur every 25 seconds

Any one know how long this lasts and does it sound effective?

Bahraha's Curse
(2 Items) Adds 1206 Max Health
(3 Items) Adds 1096 Max Magicka
(4 Items) Adds 1096 Max Stamina
(4 Items) Reduces your damage taken from environmental traps by 40%.
(5 Items) When you deal damage, you have a 25% chance to create desecrated ground for 5 seconds, which reduces the Movement Speed of enemies within 3.5m by 60%, damages them for 960 Magic Damage every 1 second and heals you for 100% of the damage done. This effect can occur once every 5 seconds

Do we know if the proc chance is still 25% patch notes said it was previously 10% and updated to 25% but I know its always been 25% hoping it just always procs since its damage and healing suck
