Cheat death bugged?

It seems to me that the talent is only partially functioning, absorbing the would be killing blow, but not mitigating damage by 90% for 3 seconds.

Or am I simply not noticing the 3 second mitigation?

As it stands the talent seems almost worthless; enveloping shadows may be the preference?

EDIT: just realized the verbiage is “up to 90%” which is… clear as mud.

yeah you need like 444 res for it to do the 90%. its a worthless talent at 60, I specced out of it during prepatch bgs

From wowpedia:

It is now reduced by a maximum of 90%, depending on how much resilience the Rogue has. The damage reduction will be four times the damage reduction resilience causes against critical strikes.
The resilience required to reach the 90% damage reduction cap is 22.5% critical strike damage reduction, or 444 resilience.

Interesting, so it does nothing without resilience other than the initial absorb

Yep, other than the initial absorb. Can be useful against big hitters to stop death then quickly vanish, but it basically does nothing considering 10% HP at 60 is like 400-450HP.

Points are better spent elsewhere
