A few thoughts on Carrion Feaster...
Let it use the 'feast' player tool that kobolds get that grant health/regen/xp below level 6-7. It's very flavorful and fits the kit perfectly.
At level 8, upgrade the ghoul corpses into something more worthwhile to have around. More damage, AC, and stun.
I don't think giving them 'onhit' ghoul touch at level 8 accomplishes much beyond flavor. I would like to see their ghoul touch spell actually increased in power significantly. DC increased, stun duration lasting longer, etcetera...
Just a few thoughts after playing one.
agreed to all of this, except I love the idea of an onhit, but agree that it is merely flavour, since your AB won't be high enough for it to matter, tbh...
You should just become a ghoul at 8.
