After killing some Turkeys last night< I wanted to share with you some observations:
1. Don't use a Pet to kill it. The Pet causes the Giant Turkey to teleport you to it, over and over again. They will use a Bleed Attack and teleport unreachable characters next to them (from 5-6 Screens away). If you die while using a Pet or Summons on it, it keeps teleporting you to it, which virtually makes it impossible to Rez, until your Pet is dead. They will most likely dispel any summons right away as well.
2. The Giant Turkeys have the highest resist to Fire and the lowest resists to Cold.
3. If you can find two turkeys nearby each other, then Provoking and then Discording one, then waiting a few minutes then discording the other is the best way to kill it. I then sic my Cu (I am riding at the time), to kill the remaining Turkey when I lore it to see it is under 600 hps.
4. Invising yourself does confuse the Turkeys and causes them to stop attacking you.
