Editing Warhammer 40,000/10th Edition Tactics/Thousand Sons (section)

====Strategy====
*Set Kindred Sorcery to '''Devastating Wounds'''.
*Slap Devastating Sorcery and Ensorcelled Infusion on a max unit of Scarab Occult Terminators that deep struck in next to what you want deleted.  You can use Cabal Points if you're short of CP.
*Take Magnus the Red, make sure he is nearby.

That's really it.  Here's what the inferno combi-bolters look like now, before we even get to the other guns you have:

A40 BS2+(Re-roll Hits) S4(Devastating Wounds, Twin-Linked, +1 to Wound) AP-1 D1

On average, that means 38.89 hits.  Assuming a T8 Sv2+ target in cover, we want to fish for crits, so 11/36 critical wounds and 5/36 chance of needing to overcome that save.  That's 11.89 mortals plus 5.4 damage after failed saves.  And the combo has yet more psychic dakka to bring to bear.

You can bring a termi sorcerer leader if you want - Lethal Hits is usually a nerf to Devastating Wounds, but you have the accuracy to fish around it when you don't want it and fish for it when you do (e.g. when you've used Twist of Fate to turn armor saves off and your target has no invuln, so Lethal Hits is much better than Devastating Wounds).
