'' It has already been stated that you cannot fire through enemy troop.''
As you can hit Jackal Clan or Warped ? I realized I wrong rules of priority target?I usually play first edition and I never use Totems against the Devout.
The main difference is that You cannot mix clans easly in 2nd edition and some stats are changed.
Fire Thrower is a defensive weapon - not used for charging! Use waiting and wait for them to approach.
Impaler can kill anything from enormous range - use two of them and using target proprity you can easly kill Soulflayer (Soulflayer is very large so can be shot even if behind skeletons).
Warped Lord and possesion - I imagine that he hides behind the skeletons (let him hide and ignore him - explained blelow)
Warped lord has 50% to succesfully cast possesion (PW 15 - level 5 = 10, if you throw out totems from your army and have average 13 LD you have 13-5 = 8 to defend so You have only 50% * 60% = 30% chances to be possesed!)
Just keep Impalers not in LOS of themselves in case of one is possesed so they cannot shoot to each other. Use them as first in turn (You cannot posses the model that was already activated)
Kill everything you can with Impalers (and crossbowmen if you take them) and just wait for them to come of finish the rest.
If you have further questions go ahead and ask
