it is instant like LoH on my lvl 66 air pet that has around 9k hp buffed it will heal about 2.5 bubs of health
added info applies to above i also have the first lvl in advanced mend companion not sure of the exact name cost 2aa
also (= i spent the 6aa 2per lvl for max hastend mending and now my mend companion refresh is under 10 min for sure i think its 9 min to be exact
for the small amount of aa spent i could not recomend this enough for the solo mage or like me the boxed mage i can tell you how many times this has made the differance between a CH landing and or landing on a dead pet now that i have the hastened mend aa maxed the bigest trouble is rembering to hit it when i dont fizz a CH to save the exra mana for the cler at 9min refresh i can use it allmost every mob in mpg or everyother
hope this was helpfull i also would like to find more info in this section (= GL
