Question Is thise AFF flags intended ?

Creating a mob i can set AFF flag curse on but not poison and charm ?

if i hit 12 for poison or 22 for charm, no aff bit is put on the mob

Charm is certainly intended, I believe poison is as well.

Charm is a spell, when a mob is charmed it obeys orders from the person that charmed it.

Poison I imagine is un-settable because if a mob loaded poisoned it'd typically wind up dying from the poison long before a player ever even found it.
