In my opinion, Taint of Corruption should be predicated on their blood. Something like:
Darkspawn Corruption (Ex): A darkspawn's blood is deadly poison to any who comes in contact with it or ingests it. It counts as a poison with the Injury and Ingested vector types and with a DC equal to 10 + Con Modifier of the darkspawn. Initial damage for the Injury vector is 1d6 Wis, secondary damage is 1d6 Wis 1 hour later. Initial damage for the Ingested vector is 1d6 Wis and Con, and 1d6 Wis and Con 1 round later.
Darkspawn often coat their weapons in their own blood, so their first successful attack is often poisoned. Darkspawn are immune to their own poison, as is anyone who has ingested Darkspawn Blood without dying (but not those who have merely suffered the Injury vector). Darkspawn Blood denatures and becomes harmless one week after it has left a Darkspawn's veins.
Any creature slain by Darkspawn Corruption rises as a Darkspawn 1d4 rounds later.
You might also want to change the wording of that trait to be "+4 against Mind Affecting spells and effects."
