I saw earlier you were looking for confirmation that the revenants can heal themselves. They can, but only a limited number of times, not only have I seen this happen but this is information available in the Runescape Knowledge base along with confirmation that they can cure themselves of poison. I have not yet been poisoned by one myself. I've only killed about 10 lvl 105 Orcs and 3 lvl 126 Knights so I may have just gotten lucky, Unlikely but it's possible. I have soloed all that I've killed so far with whip wearing d-hide armour. They don't always drop something. Mostly they drop random amounts of GP. Occasionally they drop NOTHING at all. I haven't yet gotten anything better so far but I've never been a lucky person so it may take me a good while to get anything better out of them.
