A Chaos Sorcerer(/Lord) of Slaanesh have one spell wrong. The number 2 spell Hellshriek is the previous edition. The Daemons of Chaos has the Slaaneshi spell correct "Pavane of Slaanesh". So it's just a quick fix making it so for the WoC aswell.
Thanks. (My pdfs are getting messy when I have to change spells "all the time"
