- Firstly, we’re providing updated points for lesser Daemons for free in this errata, as well as making some changes to Horrors.
- Horrors now cost slightly more points, while Pink Horrors cost less. You’ll also need 10 or more Pink Horrors in a unit to make full use of Smite.
- Finally, Plaguebearers, Daemonettes and Bloodletters now cost fewer points, making them a more attractive option when building your army.
- Secondly, if you’re a Thousand Sons player, you may have noticed that the Dark Hereticus discipline in the new codex is larger than the one in the Index. Don’t worry – the discipline isn’t being replaced and you won’t need to get Codex: Chaos Space Marines to keep using it. Similarly, if you have Codex: Chaos Space Marines, you’re welcome to use the expanded Dark Hereticus powers with your Thousand Sons Psykers. If you’re a Daemons player, this change also applies to Be’lakor.
