Drakaru 'Betrayal' quest in Zul Drak

Hi,
Just after some advice to complete the 'Betrayal' quest if possible.
I lose control of the troll before it is near death so both Drakaru and the troll attack me and I die.
I've tried with and without me attacking (with spells as an SP).
Any tips?
Thanks.

Yes. You can use 2 Trolls to kill it, along with yourself. Simply get ready to take control of another troll as the first one dies. It is doable, but yes, kinda hard.
