Destroyer Lord, Rez orb
This is 725 right now and i am not sure what else to add. I was considering another unit of wraiths to run havoc with the lord and some immortals or some destroyers.
Having another squad of wraiths would be a good call in my opinion. Two squads allow them more flexibility, also they get a better phase-out rate that way.
I think 3 destroyers would also be a great addition, grant you some long-ranged heavy firepower, or 8 immortals (drop 4 warriors). I haven't been able to run it yet, but I feel Wraiths and Immortals would work well together. Or you could just add more warriors, really I think any of those ways could work well.
Thank you! I really like wraiths, they are my favorite necron models so i am glad i can run more of them! I wanted to run it by on LO just because i was worried about fire support but 8 immortals should be plenty along with the normal warriors.
