Notes

• If you sneak up to Gareth he will comment on your skills and fully attack the Magisters assaulting him, without the Godwoken being part of the combat (if they are still on the ledge, if not Magisters turn hostile against the Godwoken that Gareth spoke with).
• Note that the quest Healing Touch will fail if you defeat the Magister party directly attacking Gareth.
• If you start the combat with the Magisters and leave the area, Gareth will die.
