I was just thinking for an added punch to help those squads but ok, Seer first
Interesting, I will incorporate that in. Sorry for all the newb questions lol
I have enough points for Exarch upgrades within the Banshee, Scorpions and Avenger squads. Any suggestions? Left over points will goto Eldrad, just don't want to use it on silly gear
EDIT: Got another box of Dire Avengers so I have 20 now
Don't get me wrong, Autarchs are good units, but compared to a Farseer I just don't think they stack up very well. Autarchs give you a solid independent character with a lot of nice options. They can be attached to a squad of Aspect Warriors and really make a difference for that squad. On the other hand, a Farseer can alter the course of the entire battle. Fortune, Doom and Guide might not seem very flashy next to powers like Jaws of the World Wolf but those re-rolls win games.
A Seer Council with Fortune is one of the hardest to kill units in the game, sometimes called a 'tarpit' unit due to their ability to soak up wounds. They're even better on jetbikes, but that's not an easy conversion and a bit pricey in 1300 points.
Doom is a very aptly named power too, since you apply it to an enemy unit and then get to re-roll every failed wound against it it's a great way to take down, say, a unit of Plague Marines/Plague Bearers. Combined with Dire Avengers using Bladestorm it can turn your opponent's toughest unit into paste. Used in melee with Witchblades you're coming as close to guaranteeing wounds as the game will allow.
Guide, for me, is the one that gets left out since I don't like to buy more than 2 powers. That said it's still incredibly useful to be able to re-roll misses, particularly if you plan on taking a Falcon. I almost consider it mandatory if you like to field War Walkers, since missing with half your shots really hurts sometimes.
I've thought it over and Eldrad is a bit too much in 1300, don't squeeze him in unless you happen to have 100 points to spare for some reason. The biggest thing he brings to the table is re-positioning your deployed units at the start: that's not very helpful if you have to severely limit your unit choices in order to take him.
Don't worry about the questions either, I'm happy to help. Make sure your Avenger Exarchs have Bladestorm, the Scorpion needs Shadowstrike. I'd skip all the powers for the Banshee Exarch but give her an Executioner, strength 5 will certainly help.
Against Daemons, you definitely want to give your Avenger Exarch dual shuriken catapults and I'd consider giving a Scorpion's Claw to the Scorpion Exarch. Just remember that you don't have to attack with the claw, against anything without a high toughness it's probably better to use the regular Scorpion Chainsword.
