Gifts of Khorne

Khorne units only.

Blessing of the Blood God: Arguably the best 5 point upgrade in the entire book. Gives you a 2+ save against any damaging psychic power or force weapons, and since there are a lot of those running around now...it's probably a good idea to take it. Especially with the rebirth of psykers in 40k, being able to protect yourself against much of what they do is a good thing.

Death Strike: A single S7 shot. Meh. Gives Khorne a quasi shooting attack, but S7 isn't very good even against Rhinos. 5+ to pen? Better than nothing I guess...

Fury of Khorne: Makes your attacks rending. With the rending nerf and the low number of attacks available to most units that can bring this...odds are, it won't ever fire. But again, it is better than nothing. Bring it if you fear Dreads and are running a pure Khorne army.

Hellblade: It's a power weapon, but isn't really an upgrade you can buy. Bloodletters and Bloodcrushers get it for free.
