An amusing read, though the part where you say a Soul Grinder isnt fearless confuses me.
*rummages through his (tiny) pile of Warhammer stuff to find his Daemon codex*

"Special Rules: Daemon (For Soul Grinders, this rule simply means they deploy like other Daemons, and are immune to Shaken and Stunned)"

That's an amusing trick. Wonder if it'll ever get FAQed.
