From the tooltip it says (taken from ESOHEAD)
"

Can someone explain it clearly to a dumbo like me ?
Does this mean NB will be healed for 25% of the damage (that he does after casting strife) for every 2 seconds
Or
Strife cause X damage. And NB will be healed 25% of X for every 2 seconds
Also it does not tell me how long does the heal lasts ?
