How about something like this? It's very much version one but at least you'll be able to get going...
Thoughts:
- The only weapon is a singing spear which has both a combat and ranged profile.
- I went with a save of 4+ as Wraithbone armour...
- Guide/doom: I wanted to include the defensive/offensive duality of Eldar powers
- Farseer runes gives a real buff to the party but only as long as as the Farseer is out of combat. the moment they engage or are engaged they lose the ability. If you keep them out of combat they could have that power active for quite a few turns but then they are down a dice at the start of each turn, as if they had been wounded.
- I'm not too sure about the renown goal but playing up the psyker aspect seemed right
Let me know how you get on!
