QuoteWithin the next 2 hours you will be resurrected immediately after dying and your HP restored to full. After triggering the effect there will be a 10 minute inhibition time. During this time it will not be possible to use Phoenix's Redemption again.
This means that you don't die technically, but it's like your HP going from 0 to maximum.
Going this way - most buffs are cleaned on exact death, that's why they stay here. And few are cleaned when HP reach 0 (no matter if you die, but in normal situation it's also die). Then buffs like Forge are intended cleaned. Shield Form must be reinitiated too, as you reach HP 0 and this is requirement of this certain buff to clean in this situation.
